Gemfields AuctionResults:Commercial-QualityEmeralds
Gemfields announces the results of an auction comprised of commercial-quality rough emeralds held during the period 11 – 29 April 2025.
Highlights: April 2025 Commercial-Quality Emerald Auction
- Total auction revenues of USD 16.4 million
- 36 lots were offered for sale, of which 32 were sold (89%)
- Average price of USD 6.87 per carat
- The 51 auctions of Kagem gemstones held since July 2009 have generated USD 1,090 million in total revenues
The specific auction mix and the quality of the lots offered at each auction vary in characteristics such as size, colour and clarity on account of variations in mined production and market demand. Therefore, the results of each auction are not always directly comparable.
Adrian Banks, Gemfields’ Managing Director of Product & Sales, commented:”Today’s result marks a notable improvement on the disappointing commercial-quality auction held in September 2024. An increased number of bids and stronger prices across a broad quality-range point to improved sentiment and demand since our experience in Q3 2024.
The overall USD per carat realisation has been positively skewed by the withdrawal of a schedule comprising very low-quality material, weighing 112,000 grams and representing 18.5% of the total weight offering.We extend our appreciation to the Kagem team and to the Government of the Republic of Zambia, Kagem’s 25% shareholder.”
The auction lots were made available for private, in-person viewings by customers in Jaipur. Following the viewings, the auctions took place via an online auction platform specifically adapted for Gemfields and which permitted customers from multiple jurisdictions to participate in a sealed- bid process.
The rough emeralds sold were extracted by Kagem (which is 75% owned by Gemfields and 25% by the Industrial Development Corporation of Zambia). The proceeds of this auction will be fully repatriated to Kagem in Zambia with all royalties due to the Government of the Republic of Zambia being paid on the full sales prices achieved at the auction.

Diamond Slump forces Debswana to diversify into copper, platinum and solar
Diamond-centric mining models is giving way to broader resource portfolios
Debswana Diamond Company, the 50–50 joint venture between the Botswana government and De Beers, is moving to diversify into copper, platinum and renewable energy as the prolonged downturn in natural diamond demand pressures earnings and forces the industry to rethink its growth strategy.
The company’s board has approved plans to invest in a portfolio of non-diamond projects after revenue fell 46% in 2024, the latest available financial year, highlighting the scale of the downturn in the global diamond market.
The move signals a strategic shift toward commodities with stronger long-term demand fundamentals, particularly copper, which is central to global electrification and energy-transition infrastructure.
Debswana’s diversification reflects a broader industry pivot as diamond producers confront weak consumer demand, rising competition from lab-grown stones and elevated inventories across the supply chain.
The shift is also visible among smaller exploration companies. Botswana Diamonds recently rebranded as Botswana Minerals, signalling its own strategic focus on copper exploration rather than diamonds.
Together, these moves underscore a growing consensus across the sector: the era of diamond-centric mining models is giving way to broader resource portfolios anchored in energy-transition metals.
