Gemfields’ Higher-Quality Emerald Auction Fetches $26.8 Million
Strong Demand Continuing For Top-Tier Stones Despite Broader Market Caution Driven By Geopolitical Tensions and Macroeconomic Uncertainty.
Gemfields reported revenues of $26.8 million from its latest higher-quality rough emerald auction, with strong demand continuing for top-tier stones despite broader market caution driven by geopolitical tensions and macroeconomic uncertainty.
The auction, held from 4 to 21 May 2026, saw 36 of 37 lots sold, representing a 97% sell-through rate. Of the 185,135 carats offered, 183,385 carats were sold, achieving an average realised price of $146.08 per carat.
The rough emeralds were mined by Kagem in Zambia. Buyers viewed the lots in Bangkok before bidding through Gemfields’ online sealed-bid auction platform.
Adrian Banks, Gemfields’ MD- Product & Sales, said:
“While demand for higher-quality emeralds remains stable, the market is presently exercising a degree of caution, influenced by ongoing geopolitical tensions and prevailing macroeconomic uncertainty…Competition and pricing for the top-tier emeralds remained particularly strong.”
Banks also pointed to the Indian rupee’s roughly 10% depreciation against the US dollar since Kagem’s previous higher-quality auction in September 2025 as an added challenge for many customers.
Dubai Diamond Exchange (DDE) and the London Diamond Bourse (LDB) have signed a Memorandum of Understanding (MoU) aimed at strengthening cooperation between the two diamond trading centres, expanding business opportunities for members, and promoting responsible growth across the global diamond and gemstone trade. The agreement was announced on 8 July 2026.
The MoU establishes a framework for collaboration in responsible trading, commercial development, knowledge sharing, and closer engagement between members of the two bourses. It also seeks to encourage dialogue on issues affecting the international diamond industry as trading centres adapt to an increasingly interconnected global marketplace.
The agreement was signed by Ahmed Bin Sulayem, Chairman of the Dubai Diamond Exchange, and Charlotte Rose, President of the London Diamond Bourse. It marks the first formal international partnership under Rose’s presidency, which began in June.
Ahmed Bin Sulayem, Chairman, Dubai Diamond Exchange, said:
“The Dubai Diamond Exchange was built on the belief that connecting markets creates opportunity. This partnership with the London Diamond Bourse reflects that philosophy, bringing together two major diamond trading centres to strengthen collaboration and expand opportunities for our respective members. The future of our industry will not be built by individual markets acting alone. By working more closely together, we can establish a stronger network of trusted trading centres, sharing expertise, upholding recognised standards, and reinforcing confidence and growth across the global diamond trade.”
Charlotte Rose, President, London Diamond Bourse, noted:
“There is no better partner for the London Diamond Bourse to begin this new chapter with than the Dubai Diamond Exchange. As a fellow member of the World Federation of Diamond Bourses, the DDE shares our commitment to trusted, well-governed trading, and this agreement opens up real opportunities for members on both sides. I’m looking forward to seeing where this partnership takes us.”
