Wholesale Diamond Tennis Necklaces

Guru Diam is a trade-only wholesale supplier and custom manufacturer of lab-grown and natural diamond tennis necklaces. Our offices are in New York's Diamond District and in Los Angeles, and production is in-house in New York and India. Order one tennis necklace or stock a full case. There is no minimum order, and every piece is paid per piece. Choose from 2 to 30 ct total weight, in all shapes, in 14K or 18K gold, platinum or sterling silver, set with CVD lab-grown melee or with natural diamonds. Every tennis necklace is made to order at the length you need, with a side or under clasp. Need a design we don't stock? You'll have a 3D CAD render within 24 hours, and the finished necklace is ready 4–6 working days after you approve it.

Wholesale pricing is visible once your trade account is approved and you're signed in. Applications submitted before 4 PM ET are approved the same business day.
