pursuit of
perfection

Global connections, patience, and a practiced jeweler’s eye pay off. The diamonds you’ll find here at O.C. Tanner are among the best in the world.

No diamond comes into our vaults by accident. Our diamond buyer Curtis Bennett travels the world looking for the most exceptional stones.

Many come from Antwerp via authorized DeBeers site holders. New York City too is a favored destination, not only because it’s home to the best diamond cutters, but also because O.C. Tanner has a personal relationship there with the oldest-living DeBeers site holder in the world.

Traveling to the International Jewelry Fair in Basel, Switzerland enables us to stay on the cutting edge of current trends and designs, as well as check up on our favorite Swiss watch makers. Then it’s on to Las Vegas, the site of the world’s largest jewelry show, to find prized colored diamonds for our collectors.
