Whether you purchase a loose diamond for mounting in an engagement ring or as part of an investment collection, North American Diamond Brokers (NADB) recommends that you always choose a certified diamond. Certified diamonds are easily identifiable and retain more value than uncertified diamonds. When you purchase a diamond that has gone through the diamond certification process, you can be confident of the quality of your diamond.

After a rough diamond has been cut and polished, most reputable diamond dealers send their diamonds to the Gemological Institute of America to be graded. The result is a GIA diamond grading report that tells potential buyers exactly what they need to know in order to make a good buying decision. The evaluation includes the analysis and grading of every characteristic such as shape, color, clarity, carat weight, cut, polish and symmetry.

The Gemological Institute of America, GIA is the foremost authority in diamond grading. They have a history of consistent and unbiased diamond grading. They invented the system that all laboratories use today. Every loose diamond brokered through NADB is thoroughly analyzed and graded by GIA. Diamonds purchased through NADB are sold with their original certificate, also called a Diamond Grading Report or Diamond Quality Report.This diamond report verifies the quality of the diamond and allows non-experts to make educated diamond buying decisions.

We have developed one of the best diamond search engines on the internet to show you only the finest diamonds available. These diamonds are:
