IN BRIEF: Gemfields emerald revenue falls amid caution, Mideast crisis

Gemfields Group Ltd - London-based miner and marketer of coloured gemstones - Says revenue generated from an emerald auction held in Bangkok from May 4-21 is USD26.8 million, down from USD32.0 million earned in auction from August 25 to September 11, 2025. Gemfields only held one Emerald auction in 2025. Says 185,135 carats were offered for sale, with 183,385 carats sold. Average realised price is USD146.08 per carat, down from USD160.78 in September. Emeralds were extracted from Zambian-based Kagem Mining Ltd, which is 75% owned by Gemfields.

"This auction result demonstrates that, 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," says Adrian Banks, managing director of product & sales. "That said, competition and pricing for the top-tier emeralds remained particularly strong, reflecting the rarity and continued desirability of exceptional gems," Banks adds.
