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.
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.
