GROWN Jewel Import GmbH is a Düsseldorf-based B2B diamond wholesaler serving professional jewellers, jewellery brands, manufacturers, designers and watch businesses worldwide. The company supplies both lab-grown and natural diamonds, with access to CVD and HPHT stones, certified natural diamonds, and melee assortments. Its offering also includes custom manufacturing, matched pairs and layouts, and support for private-label diamond solutions.

GROWN Jewel Import emphasizes consistent grading, transparent pricing and quality control. Its team inspects diamond parcels and can help clients select assortments suited to their designs, customers and price points. Natural diamonds are sourced in accordance with the Kimberley Process, with origin documentation maintained; stones over 0.30 carats are typically accompanied by GIA, IGI or HRD certification. IGI is used primarily for lab-grown diamonds, while melee parcels can include internal quality-control reports.

The company offers sample orders, recurring supply arrangements and international shipping to more than 30 countries. It also provides procurement guidance, market insights and assistance with customs and logistics, supporting ongoing wholesale relationships rather than one-time consumer sales.
