Diamond Grading

Every Jessop's diamond is graded to the three highest standards in the world - Jessop's integrity, the Gemological Institute of America (GIA) and the American Gem Society. The GIA set the standards for diamond grading many years ago. Within the jewelry industry, GIA and American Gem Society grading reports are recognized as the most accurate. As your diamond source in San Diego, we adhere strictly to these standards. Jessop's San Diego diamond store uses only these two certificates for reliability.

We employ only skilled, certified diamond graders who conduct the grading in our American Gem Society-accredited diamond lab. This diamond grading is conducted on site in our San Diego jewelry store. From diamond engagement rings to wedding rings we are San Diego's source for diamonds. Most of our diamonds also have secondary American Gem Society and GIA lab-grading reports.

The American Gem Society recently created a new diamond-grading document. This grading report, called the Light Performance Evaluation, is unique. It is a sophisticated analysis of the brilliance and dispersion, or fire, of an individual diamond resulting in a grade for light return. Jessop's finest diamonds excel in brilliance, backed by the Light Performance Evaluation. To see this for yourself, please come in and visit our San Diego diamond store.

As more people have requested diamond-grading reports, more jewelers have obliged with official-looking grading reports. Pay close attention to the lab names or initials on those reports. Only lab reports that carry the initials GIA and the name American Gem Society are the real thing. That's exactly what you will find on every Jessop's diamond-grading report - another reason Jessop's is the diamond source in San Diego.

Jessop's diamonds are the diamonds you'll be proud to give and to own. Jessop's diamonds are the diamonds for peace of mind. Jessop's diamonds are considered among the finest diamonds in San Diego and we are proud to offer diamonds for all occasions. Wedding rings, diamond engagement rings and custom jewelry design are all part of our expertise which we offer in our San Diego jewelry store.
