What Diamond Group does

Diamond Group is a Kolkata-based, privately-held real estate development conglomerate founded circa 1990 and controlled by the Kajaria family. The company develops, sells, and (until recent divestiture) operated residential apartments, commercial offices, retail malls, and industrial/warehousing parks, with a portfolio spanning over 6 million sq. ft. delivered and 8 million sq. ft. in active pipeline across central Kolkata (Crown, Niavara, The 42, Diamond Heritage), Tollygunge (Morya), North Kolkata suburbs (Navya at Madhyamgram), and Howrah-Hooghly (Urban Lakes at Konnagar). Its product range covers ultra-luxury (Crown, Niavara, The 42), mid-segment (Navya, Morya), and affordable housing (Urban Lakes), with IGBC Gold pre-certification, RERA approval, CRISIL 6-Star ratings, and RCC/AAC construction practices serving as regulatory and quality differentiators.

The group's go-to-market is direct-to-consumer, with on-site sales offices at each project, a corporate website (diamondgroupweb.com) with enquiry forms, WhatsApp Business integration, and a Kenyt.AI chatbot for lead capture. Pricing is quote-based and not publicly disclosed, with revenue realized primarily at one-time property handover; commercial and logistics assets historically generated recurring rental income. The conglomerate also operates non-real-estate businesses including lubricant manufacturing, specialty chemicals, coastal shipping, and logistics, providing capital diversification. Notable 2024 milestones include Morya's CREDAI Bengal award, Niavara's Golden Bricks Dubai recognition, and Urban Lakes' Realty+ Affordable Housing award; in 2026 Diamond Group divested Diamond Plaza (244,000 sq. ft., 98% occupied, Rs 40.1 crore FY25 revenue) to Nexus Select Trust for Rs 347.5 crore, recycling capital into the development pipeline. Leadership comprises Chairman Shri Sheo Kumar Kajaria, Vice Chairman Vivek Kajaria, and Director Shreyans Kajaria, with no disclosed external institutional investors.
