Gems One

What Gems One does

Gems One is a U.S.-headquartered B2B jewelry manufacturer and wholesale supplier that sells finished diamond and colored-stone jewelry, loose diamonds, and colored gemstones to independent jewelry retailers across the United States. Founded in 1974 by Prem Jain as a part-time gemstone business and formalized under the Gems One name in 1992 when his son Anuj joined, the company operates a New York office at 16 W 46th Street and a manufacturing facility in India, supplying more than 1,000 independent retail accounts.

Its product portfolio spans core jewelry categories (rings, earrings, bracelets, pendants, necklaces, bangles, men's jewelry) organized into branded collections such as Tru Reflections (proprietary 3D mounting that enhances sparkle), Rhythm of Love (perpetual-motion diamond mechanism), Twogether (two-stone), Mixables (stackables), Pearl, Birthstone, Charm, Diamond By The Yard, and the Perfect Love bridal sub-brand. It also sells natural and lab-grown diamonds (via the Alpha sub-brand) and colored gemstones, supported by 9,559+ active natural diamond SKUs.

Gems One makes money primarily through one-time wholesale sales of finished jewelry and loose stones to independent jewelers, complemented by marketing program services (catalogs, flipbooks, social assets, Shopify product feeds) delivered as value-added support for retail partners. Go-to-market is sales-led via a U.S. field sales team, participation in major industry trade shows, and supplier memberships in buying groups (RJO, CBG, Leading Jewelers Guild, Prime Group) and industry bodies (AGS, JA, GIA, JVC). The company is privately held, structured as Gems One Trading LLC, and recently merged with Diarough Group — the world's largest rough diamond dealer and a leading De Beers Sight holder — vertically integrating its rough sourcing and manufacturing scale.
