Loose Diamonds and Certificates

What are GIA Certified Diamonds and AGS Certified Diamonds? Loose diamonds (not pre-set in a ring or other setting) that have been certified by GIA (Gemological Institute of America) or AGS (American Gem Society).

A certificate is a "blueprint" of a diamond, it tells you the diamond's exact measurements and weight, as well as the details of its cut and quality. It precisely points out all the individual characteristics of the stone. Certificates also serve as proof of the diamond's identity and value.

 

 

A certificate is not the same thing as an appraisal. A certificate describes the quality of a diamond, but it does not place a monetary value on the gem. An appraisal places a monetary value on your diamond, but does not certify the quality of the diamond.

Who Issues Certificates?
There are many diamond labs that issue certificates, but the Gemological Institute of America (GIA) and the American Gem Society (AGS) are the two most widely regarded and recognized diamond grading labs in the world.

 

 

And while there are many other diamond grading labs in operation (many of which produce their own grading reports), dfferent labs have different grading standards, and some labs will be more lenient with their standards than others. Therefore, we recommend buying from a diamond jewelry store that offers GIA or AGS certified diamonds, as these labs have consistently demonstrated their commitment to high standards. If you do elect to buy non GIA- or AGS- certified diamonds, always ask for credentials of the certifying lab.

 

Why Do I Need a Certificate?
Shopping for certified diamonds allows you to make an informed choice about your selections, and to comparison shop. You can compare one diamond with a particular weight and quality with other diamonds of similar weight and quality to determine which is the better value.

 

What shapes of loose diamonds are available?
Loose diamonds are readily available in a wide variety of shapes including: Round, Princess Cut, Emerald Cut, Radiant, Oval, Pear, Marquise, and Heart shaped.
