Diamond Reports


Almost everyone has heard of the "4 C's" of diamond value: cut, color, clarity and carat weight. Today, there's a "5th C" called "certification."  A diamond certificate, also called a grading report, issued by a major independent gemological laboratory like EGL USA is the best way to assure the quality, authenticity, and integrity of your purchase.

The vast majority of EGL USA certificates are requested by the jewelry trade, however, consumers may send their diamonds, colored stones, or pearls directly to an EGL USA Group office for identification, grading, or laser inscription. Retail jewelers can also make lab service arrangements for you.

EGL USA is one of the largest gemological institutions in the world and grades a high percentage of all certified diamonds in the United States and Canada.  You will find EGL USA reports or certificates in many different jewelry stores, from small independent retailers to large national chains.  We offer a range of different documents for diamonds.
