What Diamcad does

Diamcad (legal entity DIAMCAD NV) is a privately held Belgian diamond manufacturer founded in 1989 and headquartered at Schupstraat 17 in the Antwerp diamond district (VAT BE 0437.109.615). The company specializes in transforming high-value rough diamonds into certified polished diamonds of exceptional quality, serving two principal enterprise segments: mining companies that recover exceptional rough stones (e.g., Lucara Diamond, Namakwa Diamonds, Sociedade Mineira Do Lulo) and luxury jewelry brands that require prestige polished diamonds for high-end collections (e.g., Graff, Chopard, Safdico). Its service is delivered as a bespoke, commissioned professional engagement rather than as a modular product, with pricing negotiated per project.

The company's technological backbone is an in-house Diamond Computer Aided Design (CAD) software platform—origin of the company name—augmented by a long-running R&D partnership with the University of Antwerp established in 1993. This collaboration produced a proprietary high-precision 3D scanning technique that models rough stones and pinpoints internal imperfections, plus state-of-the-art optimization algorithms that compute the polished-stone configuration maximizing yield across carat, clarity, cut, and color. The production stack layers laser sawing (for minimum-loss division of rough) and recently introduced automated blocking with robotics on top of expert-driven polishing. Notable end-products include the Graff Pink (23.88ct internally flawless vivid pink pear), the Graff Lesedi La Rona (302.37ct, the largest highest-clarity/highest-color diamond ever certified by GIA), the Lulo Pink (15.23ct fancy intense orangy pink heart), and the Rose of KAO (10.88ct radiant).

Diamcad makes money through a mix of commissioned cutting/polishing services for major clients and proprietary purchases of rough stones for in-house optimization and resale of the resulting polished diamonds. Its go-to-market is enterprise field sales: rough diamond experts travel to major diamond mining and trading centers worldwide to assess, source, and secure high-potential stones. The company markets itself primarily through its portfolio of record stones rather than through paid channels, maintaining only a corporate website and an Instagram presence. Diamcad became a member of the Responsible Jewellery Council in 2023 and remains privately held with no disclosed funding rounds, revenue, headcount, or external investors in the source material.
