About The Gem Lab

Joseph A. Cassarino didn’t just dream of being a jeweler. He prepared himself to be an exceptional jeweler. A graduate of the Gemmological Association of Great Britain, he opened his first jewelry shop, The Gem Lab, in 1958, armed with a prestigious gemological degree and a sterling reputation. Located in the Sibley Tower Building in downtown Rochester, New York, the original Gem Lab occupied one small room where Joe set up shop as the “jeweler’s jeweler” offering a variety of technical services, including gem identification, jewelry repair and fabrication. His esteemed Fellow of the Gemmological Association degree (FGA) and level of expertise soon gained him a loyal following among retail and major department jewelry stores.

The FGA degree is a benchmark of merit that few share. Awarded by the Gemmological Association of Great Britain, less than 175 people in the United States currently hold the title. A jeweler who has achieved an FGA offers absolute assurance to the customer that he understands the nature and various qualities of gemstones and the methods employed in their identification, grading and fashioning.

Today, The Gem Lab staff includes more than a twenty valued employees. Several serve as sales personnel, but in keeping with the Cassarinos’ focus on quality, the majority are jewelers. These artisans work behind the scenes in the full-service jewelry shop, practicing their specialties as goldsmiths, stone-setters and polishers under the guidance of Joseph and Paul Cassarino and James Salerno.

They took care of my fiancé and I for my ring and his. They’re very knowledgeable and take the time to show you everything and explain any details you want to know. My ring is even more beautiful than the display ring was and is perfectly sized. I can’t imagine having any other ring.
