What Dimexon does

Dimexon is a family-owned manufacturer and supplier of natural cut and polished diamonds, founded in 1966 by Pankaj Mehta in Coimbatore, India, with its primary legal entity (Dimexon Antwerp NV) domiciled in Belgium. The company specializes in calibrated melee, fancy cuts, and precision diamond solutions — including 0.05mm tolerance calibration on small stones — and sells directly to the world's leading watch and jewellery maisons through enterprise sales offices in Antwerp, Dubai, Hong Kong, Mumbai, and Paris. It operates a 2,000+ person workforce, with manufacturing concentrated at its Coimbatore site, which is responsible for approximately 85% of company carbon emissions and was transitioned to 75% solar power in 2024.

Dimexon's core technology stack is built around Infinitrace, a proprietary, 100% ERP-based traceability platform developed in partnership with SAP since 2007, providing auditable, end-to-end provenance from rough purchasing through polished delivery — including input-mix ratios for multi-stone parcels. This sits alongside advanced synthetic-diamond screening technology for natural provenance assurance. The business model is direct B2B enterprise sales with quote-based pricing, no public price list, and long-term partnerships as the primary commercial unit; revenue is generated through one-time sales of polished diamonds rather than licensing or subscription.

The company is governed by the Mehta family across two generations and reports no external funding rounds; it is entirely bootstrapped. Its competitive position rests on a 50+ year De Beers Sightholder relationship (since 1976), Rio Tinto Select Diamantaire status (since 2007), Responsible Jewellery Council certification, World Diamond Council board representation, Watch & Jewellery Initiative 2030 membership, Aura Blockchain Consortium membership (2024), and SBTi commitment (2023). Recent material moves include the SDTC integration in 2023, the 2024 Aura Blockchain participation and solar transition, and a 2026 brand identity refresh marking its 60th anniversary.
