SandGems

SandGems is a family-run fine gemstone house based in Antwerp’s Diamond District, where it has sourced and supplied coloured gemstones since 1979. Built on three generations of family expertise and relationships with miners, cutters and gemological laboratories, the business serves private collectors, jewellers and other trade professionals. Its collection includes certified rubies, sapphires, emeralds, spinels and tsavorites, with stones sourced from three continents. Most gemstones come with certificates from recognised laboratories such as GRS, GIA, Gübelin, SSEF and ALGT, and treatment status is disclosed.

SandGems is an accredited ethical member of the International Colored Gemstone Association and offers a virtual showroom where customers can browse stones by gem type, carat, colour, budget and certification. Clients can request specific stones, with the team sourcing to order according to requirements such as weight, origin and treatment status. The company also welcomes showroom visits by appointment in Antwerp and ships certified gemstones internationally with insurance and documentation. Verified trade members can access wholesale pricing through its members portal.
