About Us

Leon Diamond was established in 1975. Leon himself opened the business in hopes to build a legacy for his family & share those same family values with the people of New York, now... to the world. The store is still family owned & operated to this day by Leon, his son David and other members other the family. We will be celebrating its 50th anniversary in 2025!

Whether it's in store, or online, we offer a risk-free shopping experience to all of our clients by providing them with exquisite, valuable diamonds for all of the jewelry needs. All of our products are made with the most preeminent materials with extreme craftsmanship. These factors alone have driven thousands of people to Leon Diamond and have made them clients for life, including many celebrities.
