• Gemfields earned $23.1 million from its first "Trade Select" ruby auction held from June 22-29, 2026.
• The auction sold 82 of 89 lots (92.1%) and 348,409 carats out of 374,008 offered (93.2%), at an average price of $66.30 per carat.
• The rubies originated from the Montepuez district in Mozambique's Cabo Delgado province, where Gemfields owns 75% of Montepuez Ruby Mining.
• Despite challenging market conditions in some sectors, customer attendance was strong, and bidding demonstrated continued demand.

The London-based mining firm, Gemfields, recently concluded its inaugural "Trade Select" auction, generating a substantial $23.1 million from the sale of mixed-quality rough rubies. Held between June 22 and June 29, 2026, the auction featured gemstones extracted from the Montepuez district in Mozambique's northern Cabo Delgado province. This new auction format, designed to offer a broader spectrum of ruby qualities alongside newly introduced sapphire categories, represents a strategic evolution in the company's sales approach.

Out of 89 lots presented for sale, 82 were successfully acquired by bidders, marking a 92.1 percent sales rate. In terms of volume, 348,409 carats were sold from a total offering of 374,008 carats, achieving an impressive 93.2 percent. The average price realized across all sales stood at $66.30 per carat. Adrian Banks, Gemfields' Managing Director of Product & Sales, expressed satisfaction with these outcomes, noting that the "Trade Select" format was specifically developed to bridge the gap between Montepuez Ruby Mining's (MRM) traditional Mixed-Quality ruby auctions and the smaller mini-auctions that were introduced in 2025. This innovative structure aims to enhance flexibility in aligning available production with market demand while simultaneously expanding the base of participating customers.

Gemfields holds a significant 75 percent ownership stake in Montepuez Ruby Mining (MRM), which is recognized as the primary ruby mining operation in Mozambique. The successful execution of this auction underscores the continued commercial viability of the Montepuez Ruby Mining sales, contributing substantially to the Cabo Delgado mining revenue. Operating in the northern province of Cabo Delgado, MRM's activities are crucial for the regional economy. The company's ability to consistently generate revenue, as demonstrated by these latest Gemfields Montepuez ruby auction results, provides valuable market intelligence for stakeholders. This performance is particularly noteworthy given the broader operational landscape in Mozambique's extractive sector.

Despite acknowledging that certain segments of the colored gemstone market continue to face difficulties, Adrian Banks highlighted encouraging feedback from customers regarding both the new auction format and the specific composition of the offerings. He observed robust customer attendance and sustained bidding activity, which collectively indicated ongoing demand across the various categories of rubies and sapphires presented. This resilience in demand, even amid challenging market conditions, suggests a strong underlying appreciation for high-quality Mozambican rubies.

Banks also extended his gratitude to the MRM team in Mozambique, acknowledging their considerable efforts in preparing and delivering the auction despite numerous operational challenges. Looking ahead, Gemfields is already preparing for MRM's next Mixed-Quality ruby auction, which is currently slated for October 2026, signaling a continued commitment to regular sales cycles and further Montepuez Ruby Mining sales. This consistent performance offers a positive outlook for the Mozambique ruby market performance.
