The Gem Lab

Our Story

The Gem Lab is more than just a jewelry store; it's a legacy built on passion, expertise, and an unwavering commitment to quality. Founded in 1958 by Joseph A. Cassarino, a graduate of the Gemological Association of Great Britain, the store originated in a single room within the Sibley Tower Building in downtown Rochester, New York. Driven by his dream of becoming a top-tier jeweler and armed with his prestigious gemological degree, Joe carved a niche for himself as the "jeweler's jeweler." The Gem Lab quickly became renowned for offering an array of technical services, including in-depth gem identification, precise jewelry repair, and intricate jewelry fabrication.

Passing the Torch

Joe's passion for jewelry and dedication to exceptional service laid the foundation for The Gem Lab's enduring success. Over the decades, the store has evolved, expanding its offerings and expertise while retaining its core values. Today, under the watchful eye of the next generation, The Gem Lab continues to shine as a beacon of quality and craftsmanship in the Rochester community and beyond.
