Unique Diamond Engagement Rings- Cuts, Styles, & Costs

Posted on Oct 30,2014

While most people prefer classic engagement ring styles like round brilliant or princess cut solitaire engagement rings, others are more particular about the style of their rings. It’s natural to want to own something that is unlike anything found in the market. This is why many couples prefer to have their engagement rings custom-designed to suit their individual tastes and preferences.

There are many unique diamond engagement rings in the market, some feature intricate metalwork paired with unique diamond shapes or cuts and look more like wearable art than jewelry.

From uncommon metals like tungsten to unusual band designs featuring lots of intricate patterns, there are many different techniques and styles you can employ to create a truly unique engagement ring. It’s inspiring to see the diversity of engagement ring styles out there.

Cuts of Unique Diamond Engagement Rings

When it comes to unique diamond engagement rings, people are more likely to experiment with the setting rather than the diamond cut or shape. This is because the setting can easily be changed but the diamond itself is not always easy to replace.

However, if you are in the market for a less-than-common diamond cut or shape, then you may want to consider the following options:

The Triangle or Trillion

Triangle DiamondThis is a diamond shape rarely seen on engagement rings but can be a stunner when set on the right band and stone setting. While finding a perfect triangle cut is not always easy, there’s a wide-variety of triangular diamonds available online. Setting a triangle diamond on a pave band and a three-prong setting creates a good balance between classic and unique. For a more subtle design, you can set the diamond on a solitaire setting with a bezel stone setting to provide added security to the stone.

The Marquise

Marquise Diamond styleMarquise diamonds offer an advantage when it comes to visual size. Since the diamond is narrow and elongated, it typically appears bigger than it actually is.  The marquise is a modified brilliant cut and as such, it is notable for its excellent brilliance. This cut is suitable for those looking for a unique alternative to traditional brilliant cuts like the round brilliant cut or the princess cut.

The Hexagonal Cut

Hexigonal Diamond Cut

The hexagon is another unique and interesting cut for diamonds. Popular in the 1920s, this is a great option for those looking for something unique for modern standards. To protect the corners, set it on a hexagonal bezel stone setting or a 6-prong setting. You can also experiment with art deco-inspired bands to give it a vintage appeal.

Styles of Unique Diamond Engagement Rings

A popular trend for unique engagement rings is combining different fancy color diamonds on one ring. A blue center diamond paired with colorless side stones makes for a good combination. Some styles also feature double halos surrounding a center stone for extra flair. Black diamonds also go well with a tungsten band and with white accent stones for contrast.

Unique Black Diamond Ring

Most unique diamond engagement rings found in the market experiment with the setting style rather than the diamond. Tension settings are great for creating a unique ring that puts emphasis on the stone. Although tension settings are generally less safe than prong settings, they offer a great alternative to the more common four-prong or six-prong diamond engagement rings.

6-prong diamond ringA unique alternative to yellow gold is rose gold. It offers a rustic but feminine appeal than cannot be found on more common options like white gold, yellow gold, or platinum. For a unique engagement ring style, you can opt for a rose gold setting and have the band custom-designed to add vintage-inspired patterns like filigrees and floral patterns.

When it comes to creating a truly unique ring, there isn’t a set pattern or trend you should follow. Just work with your jeweler to have it designed the way you want. However, it is recommended that you still stick to classic diamond cuts, as they are easier to work with and are generally easier to find. After all, it’s easier and cheaper to have the setting custom made compared to having a custom diamond shape cut to your exact preferences.

Unique Diamond Engagement Ring Sizes

Sizes are pretty standard for most diamond engagement rings. In the US and in Canada, sizes come in a range from 5 to 13. However, there are different sizes in other countries like the UK and France so if you’re shopping abroad, make sure to have the exact measurements of the recipient’s ring finger ready.

If you are buying a ring with intricate metal work on the band, it’s best if you have the size right when you buy the ring or have it designed because it’s often harder to resize ring bands with patterns on them. You might end up having to cut the pattern or worse, ruin the pattern when you have it resized.

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.

Diamond Color Chart & Guide – What Different Colors Do Diamonds Come In?

Posted on Jul 23,2014

Diamonds come in a wide-range of colors (e.g. pink, blue, black, yellow) but in white diamonds color actually refers to the absence of color in the diamond. White diamonds are valued higher; the more colorless they appear to the naked eye.

Color is a very important characteristic in a white diamond. Part of the 4Cs of diamond grading, it is one of the most important factors that consumers consider when purchasing a stone. The GIA uses a scale of D to Z when grading diamond color, with D being the most colorless and Z showing the most color. While diamonds on the lower end of the scale can show some color, they are still categorized as white diamonds. Fancy yellow diamonds are graded differently and are valued higher the more color they show.

Diamond Color Guide for White Diamonds

Diamond Color Chart

Colorless Diamonds

D, E, F

D to F diamonds are all graded as colorless diamonds. Despite belonging to the same colorless grade, there are slight differences in color among the three but it’s difficult to spot with an untrained eye. Only gemologists and trained valuation experts are able to notice these differences in color.

Near Colorless Diamonds

G, H

G and H Diamonds are near colorless. While they show some color, it is barely visible to the naked eye. As such, diamonds in the G to H range are still considered very valuable and are priced very high.

Near Colorless – Slightly Tinted

I, J

Still categorized as near colorless, I to J diamonds are abundant in jewelry stores and other retail establishments. Such diamonds offer great value to consumers, as they sell for much lower than diamonds in the D to F range and diamonds in the G to H range white still maintaining a near colorless appearance especially when set in a platinum or white gold band. Diamonds in these color grades typically retail for 50% less than those in the D to F range.

Faint Yellow

K, L, M

Diamonds in this color range often carry some noticeable color that can be seen by the naked, untrained eye. They usually sell for half the price of diamonds in the G to H range. Setting a diamond in this color range on a platinum or white gold setting may lessen the visible yellow tinge but color is still visible when viewed up-close.

Very Light Yellow

N to R

N to R diamonds show more color than those in the K to M range and are usually avoided by many, as the yellow color may sometimes appear brown and murky. Due to the presence of color, there isn’t a very high demand for diamonds in this color range. As such, most jewelers don’t carry diamonds in the N to R color range.

Light Yellow

S to Z

Diamonds in the S to Z range show a lot of color. Like diamonds in the N to R range, there is a low demand for diamonds in this color range, which is why few jewelers stock such diamonds.

Yellow and Brown Diamonds

Diamonds that show an intense yellow or brown color are graded as fancy color diamonds. The color in these diamonds are much more intense than Z-color diamonds and are valued not for the absence of color but rather for the presence of color. The Tiffany Diamond is one of the most valuable fancy yellow diamonds discovered. It is also one of the largest, weighing 287.42 carats. Fancy yellow diamonds have gained popularity in recent years due to jewelry chains like Tiffany and Co. and some celebrity engagements.

Other Fancy Color Diamonds

Unlike colorless diamonds, which are graded for the absence of color on the stone, fancy color diamonds like blue, pink, and black are graded for the presence of color in the stone. The more intense and saturated the color in fancy color diamonds, the higher the value.

Since diamonds are priced and valued for their rarity, fancy color diamonds typically sell for much higher than colorless diamonds (sometimes, even higher than colorless diamonds in the D to F color range).

Some of the most expensive diamonds in the world are green diamonds, blue diamonds, and pink diamonds that are high in saturation. Natural black diamonds can also be very expensive especially since most black diamonds in the market are lab treated low-grade colorless diamonds.

Like white diamonds, slight differences in color on fancy color diamonds can significantly affect its value and price.

Since not all diamonds of the same color show the same amount of intensity and saturation, they are graded based on the intensity of the color they show when in the face-up position.  They are classified using the following color grades: Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Dark, Fancy Deep, and Fancy Vivid.

Basically, the more intense and saturated the color is in a fancy color diamond, the more valuable and expensive it is.

Available Colors

Fancy Colored Diamonds

Diamond colors come in a very large variety and gem laboratories use 27 different color hues to describe a diamond (e.g. orange, red, green, blue, violet, purple, orangish red, bluish-green, bluish-violet, reddish-purple, etc.)

Diamond colors can come in red, pink, purple, yellow, blue, steel gray, black, milky white, and brown. Of all the fancy color diamonds, brown diamonds are the most common. Despite being the earliest diamonds used in jewelry, they are not very popular with consumers. Consumers usually prefer brown diamonds that are very dark in color compared to lighter varieties.

Aside from rarity, fancy color diamonds typically increase in popularity when they are featured in celebrity engagements and other high-profile engagements.

Pink Diamond Engagement Rings

Posted on Jul 02,2014

Pink Engagement RingsWhile colorless diamonds are still the most popular option for many people, there is an increasing interest in fancy color diamonds like pink diamonds due to their rarity and unique appeal. Most fancy color diamonds obtain their coloring from impurities but unlike colorless diamonds which are prized especially for their flawlessness, fancy color diamonds are highly prized for the presence of color even with the presence of some inclusions.

Pink diamonds come in a range of colors, some appear brownish pink, purplish pink, orange pink, and some fancy deep pinks appear almost red. Most pink diamonds in the market are very pale as they are more common than intense pink diamonds.

Like other fancy color diamonds, the more intense the color in a pink diamond, the more expensive and rare it is.

Selling Pink Diamond Engagement Rings

Due to their rarity, pink diamonds are very much prized by jewelers and collectors. If you have a pink diamond engagement ring that you want to sell, you’ll certainly be able to find many interested buyers. However, pricing still depends on a variety of factors including the intensity of color, carat weight, clarity, and cut.

Since fancy color diamonds are graded primarily for their color before other factors are considered, it might be best if you sell your pink diamond engagement ring to a buyer who has a good understanding of fancy color diamond grading. While you can always approach a pawnshop or your local jeweler to get a quote, if you want to get a good price for your engagement ring, it’s better to sell to someone who has a lot of experience in fancy color diamond grading. Not only will they have a better idea of your diamond’s worth but they’ll also be able to offer a better price.

A good choice, especially for fancy color diamonds and other rare stones, is to sell to an online diamond buyer. Most reputable online diamond buyers have diamond valuations experts who will be able to value your fancy color diamond properly and offer you a fair price for it.

Buying Pink Diamond Engagement Rings

Buying a fancy pink diamond for engagement rings is not only a good option for those who are looking to veer away from the more common colorless variety, but it is also a good investment. As fancy color diamonds don’t wear out as easily as colorless diamonds, they increase in value overtime. Pink diamond engagement rings aren’t only valuable for their unique color but as well as for their financial appeal.

If you are in the market for a pink diamond engagement ring, then you might want to consider the following diamond grading factors when choosing the stone:

Color

Like all fancy diamonds, the value of a pink diamond increases the more color it shows. While clarity, carat, and cut are still important factors to consider when choosing a pink diamond, color is the most important consideration.

Pink diamonds are graded according to the intensity of color. The terms used for color grading are: faint pink, very light pink, light pink, fancy light pink, fancy pink, fancy intense pink, fancy dark pink, fancy deep pink, and fancy vivid pink. Other jewelers use very specific terms when referring to a pink diamond’s color. For example, you might find descriptions like “fancy deep brown pink”, “fancy light brown pink”, and “fancy vivid purplish pink” to refer to pink diamonds.

Since majority of pink diamonds in the market are of the pale pink variety, it is easier to find light pink diamonds especially for engagement rings. They are also more affordable than darker pink diamonds.

Carat

When choosing a pink diamond engagement ring, the most important consideration you should keep in mind next to color is the carat weight. Since most recipients of engagement rings have a very specific idea of how big they want the stone to be, it is best if you stay as close to their ideal size (as your budget would allow). Bigger diamonds also show more color than smaller ones especially in the case of light pink diamonds.

Clarity

The clarity of a pink diamond will depend on the shape you choose. Brilliant cuts are more forgiving of inclusions and step cuts show more inclusions. However, darker pink diamonds conceal inclusions better than lighter pink diamonds so it is often okay to sacrifice a bit of clarity for color when it comes to fancy pink diamonds.

Treated Diamonds

A cheaper option for those who want a pink diamond engagement ring is to buy a lab-treated diamond. There are different treatments used to add color to a regular diamond. However, since most color treated diamonds are of a lower grade, you should be more particular about pricing. Color treated diamonds should be cheaper than colorless diamonds and fancy color diamonds so they should be priced accordingly. Make sure not to overpay for such stones, as they are generally of the poor variety.

Color treated pink diamonds typically go through a process called annealing. Color treated diamonds should also come with a certificate stating their origin and the method of coloring used.

Where to Buy:

Amazon

Amazon carries several pink diamond engagement ring options, ranging from color treated diamonds to natural pink diamonds. You can find them in a variety of settings and styles. Below are a few notable options from their selection:


Blue Nile

Blue Nile also carries a few fancy pink diamond options, although all of their pink diamonds are of the expensive range. If you’re looking to really splurge on your engagement ring, then these options might appeal to you. You can purchase the diamond as a loose stone or choose your ideal setting on the site.

Blue Diamond Necklaces – Jewelry for Women

Posted on Jun 23,2014

Blue diamonds are fancy colored diamonds that are prized especially for the presence of color in the stone. While majority of diamonds sold in the market are in the D to Z color range, there are a few rare exceptions that show color including blue, pink, yellow, green, and even brown. While there are other stones that exhibit a natural blue color like a blue topaz or a blue emerald, blue diamonds are highly prized because of their rarity and beauty. Unlike colorless diamonds, blue diamonds and other fancy colored diamonds are much more expensive the more intense the color they show. Whereas people are willing to pay a premium to get a flawless colorless diamond in the D to F range, people are willing to pay more for diamonds the deeper the color they show when it comes to blue diamonds and other fancy color diamonds.

Unlike colorless diamonds, fancy color diamonds like blue diamonds are graded not for their fire and brilliance but for their color. Since inclusions are easily masked by the intensity of color in a blue diamond, clarity is not as important in blue diamonds as they are in colorless diamonds.

Of all the other gems used for women’s jewelry, diamonds are perhaps the most popular and most treasured. Blue diamond necklaces are especially prized for the rarity of the stone on the necklace. While not as easy to find as colorless or near colorless diamond necklaces, a blue diamond necklace will, no doubt, stand out in any occasion.

Selling Blue Diamond Necklaces

Due to their rarity, buyers are always willing to pay a premium for an authentic blue diamond. As such, selling a blue diamond necklace will yield better price offers than selling a diamond in the D to Z range.

If you have a blue diamond necklace that you want to sell (whether natural or color treated), it’s important to look for the best possible venue where you can get the best price for your necklace. After all, blue diamonds are a rare commodity and should be valued. If you want to get the best price, you can either sell directly to an individual who is willing to pay your ideal price or to an online diamond buyer. It’s best to look for an online diamond buyer who has expertise in valuing fancy color diamonds so you can get a fair price for your jewelry. Online diamond buyers will always be able to offer more for your diamond jewelry than pawnshops or jewelers because they have lower overhead costs so you can get more for your item.

Buying Blue Diamond Necklaces

You should exhibit more caution when buying a fancy color diamond like a blue diamond to ensure that what you are buying is authentic especially since some sellers might attempt to sell you other blue gemstones and label them as a blue diamond. Knowing what to look for will help you make an informed decision and will help you get the most for your money. Below are some helpful tips when buying blue diamond necklaces and other blue diamond jewelry:

Color

As the most important attribute in fancy color diamonds, you should pay close attention to the presence of color in the stone. The GIA uses these descriptions to grade fancy color diamonds like blue diamonds: fancy light, fancy intense, and fancy vivid. Fancy light is at the lower end of the scale and fancy vivid is considered the highest.

The GIA uses hue, tone, and saturation to grade the color quality of the stone. For blue diamonds, highly saturated ones are considered more rare and more valuable. The deeper the blue color is on the stone, the more expensive. It is worth noting, however, that blue diamonds don’t come in as many saturations compared to other fancy color diamonds. Blue diamonds also show a bit of gray color and are not as saturated as sapphires. Blue diamonds owe their color to the presence of boron impurities in the stone.

Clarity

While clarity is still important in a blue diamond, as long as it does not affect the stone’s face-up value, it is still highly prized. Highly included diamonds that show a lot of color can still be very expensive as the presence of color is the factor that matters the most. Unless the inclusions affect the durability of the diamond, they don’t typically affect the price.

Carat Weight

Carat weight is also an important factor in fancy color diamonds. Aside from larger diamonds being more valuable for their size, blue diamonds generally show more color the larger they are. Large blue diamonds are also very rare which is why they are highly prized.

Cut

Fancy color diamonds are typically cut into fancy shapes like radiant, pear, and oval because they show more color than round brilliant fancy color diamonds. The deeper the pavilion, the more intense the color in blue diamonds and other fancy color diamonds so this is also an important factor to consider.

Since blue diamond necklaces don’t have to be as perfect as blue diamonds used for engagement rings, you can compromise certain parameters to suit your budget especially when it comes to carat weight, color, and cut. However, if you want a truly rare blue diamond for your necklace, then be ready to pay a premium for your stone.

Grading Report

When buying a blue diamond, make sure it comes with a GIA Colored Diamond Grading Report and GIA Colored Diamond Identification and Origin Report to ensure its authenticity. The report will state the stone’s color origin (whether it is natural or treated).

Where to Buy

As previously mentioned, blue diamonds are extremely rare and as such few jewelers stock authentic blue diamonds that were not subjected to artificial coloring techniques. Authentic blue diamonds are also very expensive so others may prefer artificially colored colorless diamonds to authentic blue diamonds. Most blue diamonds available in the market are heat treated in gem labs to enhance the presence of color.

Amazon

Amazon offers a few blue diamond necklaces but most of them are color treated so if you’re truly intent on buying an authentic blue diamond, you might have trouble finding one on the site. If, however, a color treated diamond is a suitable option for you, then you might want to consider the following options:
