Loose Diamonds

Tips on Buying Loose Diamonds

"Loose diamonds" are diamonds that have been expertly cut and polished and are ready to either be mounted in an engagement ring (or other type of jewelry setting) or remain unmounted as part of an investment collection.

Cutting and Polishing a Loose Diamond

After being mined, rough diamonds are sorted based on their quality. The lower quality stones are used for industrial purposes. The more desirable rough diamonds are sent to cutting and polishing centers, where they are electronically analyzed to determine their ideal shape and carat size. The computer creates a detailed blueprint for the diamond cutter to follow. Expert craftsmen cut and polish the rough diamond to meticulous specifications for optimum brilliance.

Natural Loose Diamonds

Because diamond mining and polishing is a low-yield, labor intensive process, some diamond producers have adopted the practice of artificially altering diamond color or clarity to make them appear more valuable to the naked eye. At Brilliance, we sell only all-natural loose diamonds that have not been altered or enhanced in any way.

Certified Loose Diamonds

Certified Loose Diamonds

After being cut and polished, most high quality loose diamonds are subject to a certification process by a gemological laboratory, such as the GIA, AGS, or EGL. The laboratory evaluates each stone to ensure that it is a natural diamond, also indicating if it has been enhanced in any way. The evaluation includes the analysis and grading of basic quality characteristics, including shape, color, clarity, carat weight, cut, polish, symmetry, and proportions.

When you purchase a loose diamond that has gone through the diamond certification process, you can be confident in the quality of your stone. Additionally, stones that have been certified can be easily identified and retain more value than their uncertified counterparts.

Setting Loose Diamonds

Whether they're certified diamonds or not, most loose diamonds are professionally set into engagement rings or other fine jewelry using specialized tools, lighting, drills, and heat. Although many loose diamonds are mounted in engagement ring settings, others are used to make diamond earrings, diamond pendants, or other types of diamond rings. When used in jewelry, diamonds can take on a strong sentimental value, often passed down as an heirloom from one generation to the next.

The most premium (or rare) loose diamonds are not set, but are often acquired by museums and investors.

Purchasing Loose Diamonds

Purchasing a loose diamond instead of a diamond that has already been set offers consumers many benefits. Loose diamonds allow for easier assessment of quality, as it's more difficult to hide imperfections that would otherwise be obscured by jewelry mountings.

When you purchase mountings and diamonds separately, you'll be able to obtain a loose diamond that matches your desired specifications and quality characteristics, and then have it mounted into your chosen setting for a truly customized piece.

Loose diamonds that have been certified can easily be purchased online, saving you thousands over retail store prices. Another benefit of choosing a diamond online is expanded selection. While a jewelry store may have only a handful of diamonds from which to choose, Brilliance offers thousands of choices in our online diamond search, making it easy for customers to find the specifications they want within their price range.

There are a few important points to keep in mind when purchasing loose diamonds:

  • Look for stones that have received diamond certification from a respectable laboratory. Brilliance recommends using the world's five most trusted laboratories: GIA, AGS, EGL, IGI, and HRD.

  • Be mindful of the reputation of the diamond and jewelry retailer. Look for someone who has been in business long enough to establish trusting relationships with suppliers and customers.

  • A high-quality loose diamond will hold its value, while the setting may not.

  • Finally, be careful to strike a balance between quality and size, as bigger is not always better.
