Global Tender Network Bonas Group is the world’s largest independent diamond and gemstone tender and auction house representing 12 mines across 3 continents, presenting a wide array of sourcing and sales opportunities for mining companies and private sellers.

Strategic Partnerships Active relationships with De Beers and recent partnerships with Petra Diamonds and Gemrock highlight opportunities to expand co-marketing, sales channels, and joint tenders for rough diamonds and colored gemstones.

Funding Model Recent funding initiatives for small to mid-sized miners, including Delgatto Diamond Finance Fund collaborations, indicate a pathway to secure financing-led tenders and broaden client eligibility to participate in auctions.

Market Education Bonas engages in value chain consulting and industry reporting on lab-grown diamonds and compliance, presenting a channel to upsell advisory services, due diligence, and market intelligence to mining clients and traders.

Event-Driven Demand Active participation in industry events (ICA Congress) and high-profile tender collaborations (Gemstone, Mozambican ruby miners) create recurring opportunities to arrange targeted tender campaigns and exclusive sales for specific mineral categories.
