Your Link to the Worldwide Wholesale Jewelry Market

Since the 90s, Thurber-Roach in Warwick, RI, has been part of Polygon, a global wholesale jewelry network, where many of the world's treasured gems trade hands.

While most jewelry stores could not properly value or purchase a 7-carat diamond ring, for example, Thurber-Roach is prepared to buy – on the spot – any amount of gold, diamonds, or estate jewelry at our Rhode Island store.

With a wealth of experience in global markets, Thurber-Roach is able to pass greater value to you. Since they began working together at the original "Tilden-Thurber Jewelers" in the mid-'70s, Dave and Bill continue to be fascinated by Rhode Island's jewelry legacy.

The Polygon Network

Polygon is the largest business-to-business group of wholesale diamond dealers anywhere in the world. If you need to sell a 17th-century carved emerald ring, we can buy it because Polygon can help us find a place to sell it! As early members of the Polygon network, we aren't limited in any way by our physical location. Polygon links our RI store to the entire world of wholesale jewelry dealers.
