Guide to Black Diamond Rings – Costs, Styles, & Sizes

Posted on Oct 25,2014

Natural black diamonds are extremely rare and are only found in two places in the world, Brazil and the Central African Republic. As such, most black diamonds used for jewelry are heat-treated low-grade colorless diamonds.

The color of natural black diamonds is either black or dark grey and is caused by graphite inclusions in the stone. Black diamonds are the toughest natural diamonds and they are usually denser than colorless diamonds. Natural black diamonds are porous and are made up of millions of small crystals stuck together. Due to its composition, it is a lot more difficult to cut into different shapes compared to other diamonds.

Unlike colorless diamonds and other fancy color diamonds, black diamonds absorb light instead of reflecting it. Due to the unique appearance of the stone, more and more people are choosing to buy black diamond rings over traditional colorless diamond rings.

Costs of Black Diamond Rings

There is a lot of mystery surrounding the formation of black diamonds; some theories state that black diamonds or carbonados come from outer space as a result of a supernova whereas others believe that black diamonds were formed by meteoritic impact on the surface of the earth. The most common theory, however, is that black diamonds are formed in the earth’s interior under extreme high-pressure and heat.

Regardless of the actual formation of natural black diamonds, these theories have a hand in increasing the price of black diamonds in the market.  Due to large interest in the mysteries surrounding the black diamond, there has also been an increase in the demand for natural black diamonds in the market.

Lab-treated black diamonds (those that are heat-treated through irradiation to change the color to black) are generally cheaper than colorless diamonds because they are usually made from low-grade colorless diamonds. The prices of lab-treated black diamond rings typically start at $1400 if the quality of the stone is relatively decent.

Natural black diamonds, known as fancy black diamonds, are generally very expensive because they are extremely rare. Price is determined by the intensity of the color, the absence of white inclusions in the stone, and the stone shape. The price for the average fancy black diamond typically starts at $2000 to $2500 per carat. Due to the difficulty of the cutting process, larger black diamond rings are a lot more expensive than smaller stones. For instance, a 3-carat fancy black diamond can cost over $8000 whereas a 9-carat stone can cost over $27000 without the ring setting.

Natural black diamonds typically have dark brown edges when viewed under a fiber optic light whereas black diamonds treated through irradiation appear dark green under the same light. It’s a quick way to determine whether a black diamond is natural or treated.

Styles of Black Diamond Rings

Black diamond rings come in a wide-range of styles. The unique, dark color of the stone makes it suitable for experimenting with different settings.

For instance, a growing trend in the jewelry market is setting a black diamond (whether natural or irradiated) in a tungsten ring band. Since both are black, they complement each other quite nicely. For a bit of contrast, small white diamonds are added as accent stones or a white gold or platinum stone setting is used to create contrast against the tungsten band.

It’s also fairly common to set a round black diamond in a halo and pave setting with small white diamonds as accent stones. Since black goes better with white, the most common material used for black diamond rings are silver, white gold, and platinum.

Rose gold and yellow gold are also used but they are relatively rare because the color of the stone clashes with the color of the metal.

Style is, of course, subjective so it’s up to you to decide which metal is suitable for a black diamond ring. While there is certainly a lot of interesting black diamond rings in the market, custom rings are always an option if you can’t find one that suits your taste.

Sizes

Black diamond rings come in standard ring sizes. In the US and Canada, the standard ring sizes come in sizes 5 to 13. In the UK and in other countries, different sizing values are used so it’s best to measure your ring size in inches or centimeters so you can easily convert to its equivalent size in the country where you are purchasing the ring.

You can obtain the size of your ring finger either by using a standard ring size chart or by wrapping your ring finger in a piece of paper or string and manually measuring the length with a ruler.

If you are buying for someone else, it’s best to just discreetly borrow a ring from that person so you can use it for sizing when you buy the black diamond ring. Don’t worry if you don’t get the size right, as most jewelers offer resizing services for free if you purchase the ring from them.

Guide to Blue Diamond Rings – Costs, Styles, & Sizes

Posted on Oct 03,2014

While not as popular as colorless diamond rings, blue diamond rings also has its share of the jewelry market. They are suited especially for people who are looking for a unique alternative to colorless diamonds.

Unlike colorless diamonds that are valued for the absence of color on the stone, blue diamonds are valued based on the intensity of color. There is also a different grading system for fancy color diamonds like blue diamonds.

Instead of being graded for their fire and brilliance, they are graded for the amount of color they show. As such, they are graded from light (showing the least color) to vivid (showing the most color).

For fancy color diamonds like blue diamonds, color is top-priority for jewelers.

Cost of Blue Diamond Rings

Compared to other fancy color diamonds, blue diamonds are very rare. Blue diamonds in the fancy intense and fancy vivid range are the rarest and most expensive.

Since natural blue diamonds are rare, a lot of the blue diamonds sold in jewelry stores are color-treated white diamonds. This is why it is important to check the origin report of the diamond before making a purchase to find out whether it is natural or color-treated.

Color-treated blue diamonds are relatively inexpensive since they are usually low-grade colorless diamonds that are treated to change color. Color treated blue diamond rings can cost anywhere from a few hundred dollars to thousands of dollars, depending on the treatment method, carat weight, clarity, and ring setting.

Natural blue diamonds, however, can cost as much as $250,000 per carat depending on the color intensity. Blue diamonds from the fancy light color range can also cost as much as $100,000 per carat, depending on the clarity and overall carat weight of the stone.

While clarity is also a consideration in pricing, color is still top-priority. As such, intense blue diamonds with visible inclusions are still priced very high as long as the face-up color value is desirable.

Styles of Blue Diamond Rings

Like colorless diamonds, blue diamond rings come in a wide-range of styles. For blue diamond engagement rings, halo and pave settings are very popular. These rings feature one large blue diamond in the center surrounded by a halo of small colorless diamonds on a pave diamond band.

Solitaire diamond rings are also very popular and are typically set in a prong setting of white gold. White gold and platinum are the most popular metals used for blue diamond rings but some styles also feature a combination of both yellow and white gold. A popular style for mixed metals is setting the diamond on a yellow gold prong stone setting and a white gold ring band.

While most blue diamond rings are paired with colorless diamond side stones, some also choose to pair blue diamonds with other fancy color diamonds like pink, yellow, red, or black.

There are some very unique blue diamond rings available online, such as art deco-inspired rings and blue diamonds set on a black band made of tungsten carbide.

When it comes to blue diamond ring styles, the options are virtually unlimited. If you can’t find a style you want, you can always have a blue diamond ring custom-made by a jeweler to suit your exact preferences.

Sizes

Blue diamond rings can come in just about any ring size. If you’re shopping for yourself, then you can easily find a ring that fits you or have a ready-made ring resized for your finger.

However, if you are shopping for someone else, a good option would be to borrow a ring from the recipient and measure its size using a standard ring size chart.

In the US and Canada, ring sizes range from 5 to 13 and in the UK, ring sizes range from A to Z. Other countries may use different values for sizes so if you’re shopping abroad, it’s best to just convert the US ring size to its equivalent in the country you are buying the ring from.

You can always have the ring resized if you get the wrong size but for engagements, it’s always a plus if you get it right the first time.

Guide to Rose Gold Engagement Rings – Cost, Styles, & Sizes

Posted on Sep 17,2014

Rose gold is a unique alternative for people who don’t want the more traditional yellow or white metals (i.e. yellow gold, white gold, platinum) on their engagement rings. While rose gold engagement rings are not as popular as those set on yellow or white gold, they are increasing in popularity among many couples due to the unique charm and elegance. They are especially popular in women’s jewelry.

Rose gold is not a natural color; it is achieved by mixing yellow gold with copper and silver. An 18 Karat rose gold ring, for instance, typically has 75% yellow gold, 2.75% to 4% silver, and 21% to 22.25% copper. This type of gold was highly popular in Russia in the 19th century and was widely called Russian Gold at the time. Now, it is just marketed as rose gold.

A higher-end version of rose gold is known as crown gold or 22-karat rose gold This type of rose gold has the highest gold content, containing about 91.667% (22 out of 24) of gold mixed with copper. Crown gold, however, is not recommended for jewelry because it is susceptible to scratches due to its high gold content.

It is worth noting that, although somewhat similar in appearance and color, rose gold is different from pink and red gold. While all three colors are achieved by mixing gold and copper together, differences in color results from the amount of copper mixed with gold.

While the amount of copper mixed with gold can vary, the amount of gold is still the same as yellow gold.

Due to their copper content, rose gold engagement rings are quite durable and are suitable for daily use.

Cost of Rose Gold Engagement Rings

Just like yellow or white gold engagement rings, the price of the ring is affected by the purity of gold. While the stone is still the most expensive part of the ring, you can expect a 14-karat rose gold band to be cheaper than an 18-karat rose gold band.

While 14K and 18K rose gold are the most commonly used in engagement rings, there are 10K (contains 41.6% yellow gold mixed with copper and silver) and 9K (contains 37.5% yellow gold mixed with copper, zinc, and silver) rose gold varieties available. These are commonly used in wedding bands but can also be used in engagement rings.

The cost of rose gold bands (without the stone) typically ranges from $100 to $700, depending on the gold content. It is better to know the price of a rose gold band separate from the actual engagement ring with the stone so you can properly calculate costs when shopping for a ring. This is especially useful for those who want to buy the diamond separately.

The cost of rose gold engagement rings (complete with the stone) can vary greatly depending on the size and quality of the diamond or gem used.

When calculating the average price of rose gold engagement rings, you can compare prices online or take a look a look at the current market price of gold. While the market price of gold is not the only factor that affects jewelry pricing especially in jewelry stores, it does have a significant effect in retail pricing as well.

Styles of Rose Gold Engagement Rings

Just like other engagement rings set in more common metals like yellow gold or white gold, rose gold engagement rings come in a wide array of styles. You can find virtually any style you want online or have a specific style custom made by a trusted jeweler. Whether you prefer the simple elegance of a solitaire rose gold engagement ring or the sparkle of a halo rose gold engagement ring with side stones, the options are endless.

A popular style in engagement rings is pairing a pink diamond with a rose gold band. This is because the rose color of the metal emphasizes the pink hue in a pink diamond.  However, since pink diamonds are relatively rare and their appeal is highly subjective, most rose gold engagement rings available in the market use colorless diamonds. It is also common to use both rose gold and white gold in one ring especially in halo style engagement rings. In some styles, rose gold is used for the band and white gold for the stone setting.

Sizes

Knowing the recipient’s ring size is important when shopping for an engagement ring. While you can always have the ring resized, it’s always better to get it right the first time. You can use a ring sizer to determine the size of the recipient’s ring finger. If you want the ring to be a surprise, you can print out a ring size chart and take one of the recipient’s existing rings for sizing.

Rose gold engagement rings can be customized to fit any size. In the US and Canada, ring sizes range from 5 to 10. The size is determined by diameter and circumference. If you are shopping abroad, you can use an international ring size chart or simply convert the US standard size to its equivalent in another country.

4Cs Diamond Chart – Cut, Clarity, Carat, and Color

Posted on Aug 25,2014

Buying a diamond might seem like a daunting task especially for the first-time buyer but using established standards to determine what sets a quality stone apart from the rest should make the process a whole lot easier. Anyone who is interested in buying a diamond or learning more about diamonds should start with the 4Cs (Cut, Clarity, Carat, and Color). Established by the GIA (Gemological Institute of America), the 4Cs is the global standard used for grading and describing diamonds.

The 4Cs in Detail

The 4Cs make it easy for jewelers to set prices for diamonds and consumers to determine whether a particular diamond suits their personal preferences. A diamond’s characteristics based on standards of cut, color, clarity, and carat heavily determines its value.

Cut

Some people mistake a diamond’s cut for a diamond’s shape. Cut is different from shape. A diamond’s cut refers to how it is proportioned, its symmetry, and as well as its polish.  A diamond’s cut is determined not only by the quality of the rough stone but by the craftsmanship and preciseness of the diamond cutter. Cut is very important in a diamond, as it can greatly affect its external appearance. Even the most flawless of diamonds can look dull if not cut to exacting proportions.

The GIA uses the following grading system to describe a diamond’s cut:

Excellent

A diamond with an excellent cut grade offers maximum fire (amount of light that is reflected by the diamond as result of the optimum dispersion of light as it enters the diamond) and brilliance (brightness of the diamond). It is neither cut too deep nor too shallow. It also has excellent symmetry (refers to how each facet of a diamond is angled to allow for maximum brilliance) and has excellent polish  (refers to how smooth each facet is).

A diamond that has an excellent cut grade is able to reflect most of the light that enters the diamond.

Very Good

Diamonds that are graded “Very Good” are cheaper than excellent cuts but are almost very similar in terms of fire and brilliance when viewed with normal lighting. While there are differences in cut quality compared to excellent cut diamonds, it is unnoticeable to the untrained eye.

Good

Diamonds that are graded “Good” in terms of cut quality offer the best value for money. They are not nearly as expensive as diamonds with very good or excellent cut grades but they offer superior fire and brilliance. Such diamonds are able to reflect most of the light that enters the diamond.

Fair

A diamond with a fair cut grade allows most of the light that enters the stone to escape either from the bottom or the sides of the diamond. As such, fire and brilliance is significantly reduced resulting in a dull and lifeless appearance especially for bigger stones. It is recommended not to get a diamond with a fair cut grade for stones that are bigger than .75 carats, as the effects of the cut quality are quite apparent.

Poor

Diamonds of poor cut grading cannot reflect majority of the light that enters it. Instead, most of the light is allowed to escape from the bottom and sides. As a result, diamonds of this caliber are very dull and lifeless. Most jewelers don’t offer diamonds of poor cut grades because of the low demand.

Since Cut is the most important quality when it comes to a diamond’s appearance, it is important to pay close attention to a diamond’s cut grade. Cut is extremely important in brilliant cuts like the round brilliant and princess cut, as these diamond shapes are valued for their excellent fire and brilliance.

Clarity

Most diamonds contain inclusions (imperfections within the diamond). Inclusions that are concealed or hidden from plain sight are ideal because they don’t affect the way a diamond reflects light. Inclusions that are very visible can affect the way light bounces on individual facets of a diamond and can therefore greatly affect a diamond’s fire, brilliance, and scintillation.

A diamond’s clarity is graded based on the quantity of inclusions and their location in the diamond.  The GIA uses the following parameters to describe a diamond’s clarity grade:

FL (Flawless)

Do not contain any visible inclusions (internal flaws) and blemishes (flaws located on the surface) even under 10x magnification. These diamonds are virtually flawless and are extremely rare and expensive.

IF (Internally Flawless)

IF diamonds have no visible inclusions or blemishes unless viewed under 10x magnification by a trained expert.

VVS1 VVS2 (Very Very Slightly Included)

VVS1 and VVS2 diamonds contain some inclusions and blemishes but they are not visible to the untrained eye. Even under 10x magnification, only a skilled grader is able to spot the inclusions on a diamond of VVS1 or VVS2 Clarity.

 

VS1 VS2 (Very Slightly Included)

Diamonds of VS1 or VS2 clarity grades contain minor inclusions that are not visible to the naked eye. The inclusions can only be seen under 10x magnification.

SI1 SI2 (Slightly Included)

Diamonds with SI1 clarity contain inclusions that are still invisible to the naked eye and can usually only be observed under 10x magnification. SI2 diamonds, on the other hand, contain inclusions that can be seen by the naked eye upon close inspection.

I1, I2, I3 (Included)

I1 to I3 Diamonds contain very visible inclusions that can be observed by the naked eye. I2 and I3 diamonds usually contain inclusions that can affect a diamond’s overall quality and appearance.

Color

The color of diamonds, except for fancy color diamonds, are graded based on the absence of color in the diamond. Colorless diamonds are very clear and contain no traces of color (e.g. yellow or brown).

Diamond color is graded on a scale of D to Z. D, E, and F diamonds are considered the rarest, as they are virtually colorless whereas diamonds in the G and H color range are near colorless except for a slight tinge which can be eliminated with the proper setting (e.g. white gold or platinum). Diamonds in the I to J color range offer the best value for money, as they are about 10% cheaper than diamonds in the G to H range but still appear colorless to the naked eye.

The chart below illustrates the color range of diamonds from A to Z.

Diamond Color Chart

Carat Weight

While many people think of carat weight in relation to a diamond’s size, it actually refers to how heavy a diamond is. The size of a diamond is determined by its diameter and crown size (measured in mm and mm2, respectively).

A diamond’s value increases the heavier it is, although two diamonds of the same carat size can have different prices depending on their cut, color, and clarity. In addition, two diamonds of the same carat weight can have different sizes depending on how they are cut.

Most diamonds of equal quality are sold on a price-per-carat basis. So if a diamond is priced at $3000 per carat, you can expect to pay double that amount for a 2-carat diamond of the same quality. This system makes it easier to compare prices and determine budgets for diamonds of the same quality.

The chart below illustrates different diamonds of varying carat weights in relation to their size in mm.

Diamond Quality Chart & Guide – What Affects the Value of a Diamond?

Posted on Aug 21,2014

Even when taken from the same rough stone, no two diamonds are the same. Each diamond has unique characteristics that determine whether it is a cut above or below the rest.

There are several factors that affect the value of a diamond but gemologists worldwide have come up with a common system to easily determine a diamond’s grade and value. This grading system is known as the 4Cs of a diamond. How a diamond fares based on the parameters of cut, color, clarity, and carat affects its overall value (not just monetary value but consumer demand as well).

Rarity

Rarity greatly influences the value of a diamond to a jeweler or a consumer. While diamonds come in almost every color of the rainbow, the most common diamonds available in the market are those that show a bit of a yellow tinge. As such, diamonds that are colorless (i.e. those in the D to F color grade) are greatly valued because they are more rare than diamonds in lower color grades.

Black diamonds are also very rare; so rare in fact that most black diamonds available in the market aren’t natural black diamonds but lab-treated diamonds (usually those from lower color grades). Due to their rarity, they are very expensive.

Cut

Every diamond expert or jeweler always emphasizes the importance of cut in a diamond. It is one of the most important factors that can affect a diamond’s value. Even the most flawless of diamonds can be dull and lifeless if cut in the wrong way. As such, a diamond cutter needs to be very careful and precise during the cutting process, as the slightest mistake in cut can affect the overall value of a diamond.

A well-cut diamond will have maximum fire and brilliance, as it is able to reflect most of the light to the crown or the surface of the diamond for the viewer to enjoy. A poorly cut diamond, on the other hand, will allow most of the light to escape from the bottom or the sides of a diamond and will have a very dull and lifeless appearance when viewed from the crown. To achieve the ideal fire, brilliance, and scintillation, a diamond has to have symmetrical facets and should not be cut too deep or too shallow. In other words, it should be perfect and precise.

Clarity

Most diamonds have natural defects within them called inclusions. As they are buried deep in the ground, inclusions are inevitable. However, there are some diamonds that either come with very few inclusions or none at all. Diamonds with very few or no inclusions are very rare and as such, are very valuable and expensive. Inclusions don’t only affect how flawless a diamond looks but it can also affect how the light bounces on the facets when it enters the diamond. Inclusions can therefore affect how much light is reflected on the surface of a diamond.

When valuing a diamond based on clarity, valuation experts don’t only look at the number of inclusions in the diamond but as well as their location and visibility. Inclusions located in places that aren’t visible to the naked eye (i.e. the girdle or under the bezel) are acceptable because they don’t affect the way light is reflected by the facets in a diamond.

Color

In majority of diamonds (except fancy color diamonds), color means the absence of a yellow tinge in the diamond. Colorless diamonds (i.e. those in the D to F color grade) are priced very high. However, color is subjective and some people don’t mind a bit of a yellow tinge as long as it is a well-cut diamond.

Since the demand for colorless diamonds is higher than those that exhibit a visible color even without magnification, diamonds are considered more valuable the higher they are in the diamond color scale.

Fancy color diamonds, on the other hand, are valued for the presence of color in them. Highly saturated fancy color diamonds are very valuable because of the vibrancy of color in them.

Some fancy color diamonds are very rare (i.e. black diamonds, blue diamonds). To make up for the lack of supply, many gem laboratories subject a low-grade colorless diamond to heat and pressure treatment to enhance the color of a diamond or to change its color into a fancy color. Lab treated diamonds are of course cheaper than naturally colored diamonds.

Carat

Carat refers to the weight of a diamond. The higher the carat weight, the more expensive the diamond. This is because larger diamonds yield more waste when cut from the rough stone compared to smaller diamonds. Diamond size is measured in mm and weight is measured in carats (1 carat is roughly 0.02 grams). Many people prioritize carat weight over cut quality but to get a truly beautiful stone, it is important to look for a balance of carat size and cut quality.  While a diamond’s value greatly increases the bigger it is, large diamonds that are lower in the color and clarity grade are generally priced lower than smaller diamonds that are well cut, colorless, and flawless.

There are many other technical factors that affect the value of a diamond but the aforementioned factors are the most important. The 4Cs of valuing a diamond are universally used as these parameters make it easier for gemologists, jewelers, and consumers to find out how valuable a diamond is.

Diamond Grade Chart – Grading Diamonds for their Value Using the 4C’s

Posted on Aug 04,2014

A diamond’s grade is often what determines its price and value. Most diamonds sold in jewelry stores and online stores come with a diamond grading report that illustrates its qualities and specifications. Larger, higher-grade diamonds typically come with a grading report from a reputable third party institute like the Gemological Institute of America (GIA), EGL, AGS, and others.

A diamond’s grade is determined by the 4Cs (cut, color, clarity, and carat weight). While there are other factors that can affect a diamond’s physical appearance and value, the four Cs of a diamond are the most important characteristics. As such, gemologists worldwide use these four parameters to determine the grade of most diamonds.




Diamond Grade Chart

Cut Grade

Chart of different Diamond Cuts

When buying a diamond, one of the most important factors you should consider is its cut grade. The cut determines a diamond’s physical appearance and as such, should be prioritized. Diamond cut is graded from excellent (provides maximized brilliance, reflects the most light back to the surface) to poor (most light escapes at the bottom or the sides of the diamond, providing little to no brilliance).  Below are the most important parameters that determine a diamond’s cut grade:

Cut Proportions

A diamond’s cut proportions affect the stone’s fire, brilliance, and scintillation. It is determined by how each facet in the diamond is angled, sized, and shaped. In a well-cut diamond, each facet is strategically placed so that the most amount of life is reflected out of the crown for the observer to enjoy. A poorly cut diamond (i.e. too shallow or too deep) does not reflect much light because the facets allow the light to escape from the bottom or the sides instead of being reflected back to the observer’s eye.

Symmetry

As the term suggests, symmetry refers to how symmetrical the facets of each diamond are in relation to each other (i.e. how each facet aligns and intersects). A diamond’s symmetry is graded from excellent to poor.

Polish

Polish is determined by how smooth the facets are in a diamond. A diamond with an excellent polish will not show any defects even under 10x magnification whereas a diamond with poor polish will show defects even without magnification.

Other factors that determine a diamond’s cut grade include girdle width and culet size, which also affect a diamond’s brilliance and overall appearance.

Color Grade

In colorless diamonds, color grade refers to the amount or lack of color in a diamond. The more colorless a diamond, the higher its color grade. Colorless diamonds are more valuable than diamonds that show a yellow tinge.

Colorless diamonds in the D, E, and F color range are the most expensive of all.  Diamonds in the G to J range are still near colorless but there is about a 10% price difference in each color grade. Diamonds in the I and J color range have the most demand in the market because they are readily available and offer great value for money.

GIA Certification Color Grading Scale

Clarity Grade

All diamonds contain inclusions  (defects or blemishes within the diamond). Inclusions can affect a diamond’s physical appearance, as it can interfere with the passage of light in the diamond, which in turn can affect the amount of light reflected back to the surface. A diamond’s clarity grade determines the amount of inclusions in the diamond. When grading a diamond, gemologists consider several factors including the position, size, and quantity of these inclusions under 10x magnification. Inclusions that are located in the girdle or under the bezel of a diamond is ideal because they are not visible and barely affects a diamond’s brilliance.

The GIA uses 11 categories for a diamond’s clarity these include: flawless (FL),  internally flawless(IF), very very slightly included (VVS1, VVS2), Very Slightly Included (VS1, VS2), Slightly Included (SI1, SI2), and Included (I1, I2, I3).

Brilliant cuts are more forgiving of inclusions because their facets are positioned in such a way as to maximize brilliance whereas other fancy cuts like the emerald cut and asscher cut (which are step cuts) are less forgiving of inclusions.

Carat

Of all the qualities of a diamond, the carat weight is probably one of the most important for most people. Diamonds can significantly increase in price and value the bigger it is. This is because rough stones that can produce a 1-carat diamond is rare. This is why price increases so much as you go up per carat.

It is worth noting, however, that carat refers to a diamond’s weight and not necessarily its size. The size of a diamond is determined by its diameter and crown size. This means that two diamonds of the same carat weight may not necessarily have the same physical size when viewed from the top. Its cut proportions determine the actual size of the diamond; carat weight merely refers to how heavy the diamond is. The length x width ratio of a diamond also determines how big it will appear once set in a ring.

All the characteristics mentioned above determine how valuable a diamond is and are therefore, dependent of each other. While no two diamonds are virtually the same, these parameters help jewelers and consumers determine the price and value of a diamond.
