About Jessop's Expertise

There are very few - only 2,000 - jewelry stores in the nation accredited by the American Gem Society - and Jessop's is one. Only jewelers with the highest standards of professionalism, ethics and education are accepted as members. Our goal is to offer the finest selection of diamonds for engagement rings and custom jewelry of any San Diego jewelry store.

Out of approximately 455 American Gem Society-certified gemologists and American Gem Society-certified gemologist appraisers in America today, Jessop's has two - a unique achievement and honor. We also have an American Gem Society-accredited gem lab in our San Diego jewelry store.

Our custom craftspeople include an in-house master goldsmith/platinum-smith. Our watchmakers are Swiss-trained and experienced in working on all of the world's fine timepieces. This includes vintage watches, which we repair and restore, and the finest new watches, which we are authorized to repair using genuine parts.

Every Jessop's jeweler, gemologist and craftsperson exemplifies the highest levels of accomplishment in the jewelry industry. As your source for diamonds in San Diego, we strive to provide only the highest quality jewelry to all of our customers.
