Diamond Leaders

Diamond Leaders is a New York jewelry retailer specializing in IGI-certified lab-grown diamond pieces. Based at 580 Fifth Avenue, the company has sold diamonds online since 1999 and says its own team checks each piece before shipping. Its collections include rings, earrings, necklaces and bracelets, with designs ranging from engagement rings and diamond studs to tennis jewelry. Pieces are offered in solid 14K gold or 14K gold over solid sterling silver, with the material specified for each product. The brand describes lab-grown diamonds as real diamonds with the same carbon composition, hardness and brilliance as mined stones, while highlighting their different origin and value.

Diamond Leaders offers free, fully insured FedEx 2Day Air shipping to US addresses and a 30-day return period for items in original condition, with return shipping covered. Many ready-to-ship items leave within 24 to 48 hours, though delivery may take up to two weeks. Ring resizing is also available. Each diamond piece comes with an IGI certificate, and shipments require a signature.
