Buying a Loose Diamond

Buying 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. (Want to speak with a diamond expert? Call 866-737-0754 for expert advice on selecting the perfect loose diamond.)

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 buying loose diamonds 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.

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.
