What Mahendra Brothers does

Mahendra Brothers (legal entity: Mahendra Brothers Exports Private Limited) is a privately held, family-controlled natural diamond company founded in 1960 in Mumbai, India, with roots tracing back to the Parikh family's diamond business established in 1940. The company operates a fully integrated natural diamond ecosystem spanning rough diamond sourcing as a De Beers Sightholder since 1969 (alongside Rio Tinto, Burgundy Diamond Mines, CanadaMark, and Forevermark supply relationships), three specialized polishing and manufacturing facilities in Navsari, Gujarat segmented by carat size (30pts+, 30pts and lower, 18pts and lower), and finished diamond jewellery manufacturing through the wholly owned Uni-Design subsidiary (established 1995 at SEEPZ Mumbai) with four facilities serving both Indian domestic and international markets.

The underlying technology stack combines advanced CVD detection laboratories that test every inbound and outbound diamond for natural origin, laser mapping and cutting technology (Sarine partnership) for high-end special cuts and yield optimization, proprietary internal tracking systems supporting full Kimberley Process compliance and Tracr blockchain-based end-to-end traceability from rough sourcing to polished delivery, fully digitized operations synchronized to central servers, and GIA/IGI/HRD/GCAL third-party grading integrations. The company maintains precision-calibrated output down to 0.001 ct including Hearts & Arrows cuts, with a workforce of 5,000+ skilled artisans at the diamond facilities plus 2,500+ professionals at Uni-Design.

The business model is B2B diamond and diamond jewellery supply to jewellery manufacturers, luxury brands, private-label brands, and retailers globally (from single-store owners to large chains). Revenue streams include polished natural diamond sales (cuts including round, princess, oval, pear, marquise, emerald, cushion, heart, radiant, tapered baguettes; clarity VVS to I2; color D to K; sizes 0.001 ct to 3.00 cts), rough diamond procurement and trading via the Sightholder allocation, and finished diamond jewellery manufacturing through Uni-Design. Pricing is quote-based and not publicly disclosed; the go-to-market combines dedicated enterprise account managers with a live authenticated self-serve inventory portal (emb.mahendrabrothers.com) supporting registration across Consumer, Retailer, Wholesaler, Jewellery Manufacturer, and Other buyer types. Group-level ESG positioning is anchored on the Sustainaire platform, with CSR executed through the Parikh Foundation (since 1985).

Direct peers

• Hari Krishna Exports: Indian De Beers Sightholder and one of the largest polished diamond manufacturers globally, with manufacturing scale and B2B jewellery customer base closely overlapping Mahendra Brothers' core business.
• Diarough: Global diamond manufacturer with strong Indian manufacturing operations and sightholder-equivalent rough access. Directly comparable as a vertically integrated polished diamond supplier serving jewellery brands and retailers.
• Rosy Blue: Multi-generational family-owned global diamond manufacturer with Indian cutting operations, long-standing sightholder relationships, and a B2B polished diamond value proposition closely aligned with Mahendra Brothers'.
• KGK Group: Vertically integrated Indian diamond and coloured gemstone group with rough sourcing, manufacturing, and jewellery operations spanning global markets. Comparable as a family-owned integrated player operating across similar value-chain stages.

Broad incumbents

• Titan Company (Tanishq): India's largest jewellery retailer and a Tata group company, operating across gold, diamond, and branded jewellery. Comparable as a downstream buyer/incumbent in the natural diamond jewellery value chain though with a fundamentally different GTM (branded retail vs. B2B manufacturing).
• Chow Tai Fook Jewellery Group: Hong Kong-headquartered global jewellery retailer with vertically integrated diamond sourcing and manufacturing. Comparable as a large incumbent operating across the same natural diamond value chain but anchored in branded retail rather than B2B manufacturing.
