Gemfields Generates $4.8 Million from Mini-Auction of Higher-Quality Emeralds
Mini-auction of unsold emeralds from November 2024 shows a promising rise in demand and prices, with 77% of lots sold.
Gemfields has reported strong results from its mini-auction held from February 19 to 21, 2025, featuring higher-quality emeralds that had remained unsold during its November 2024 auction. The event raised $4.8 million in revenue, signaling a notable recovery in demand and pricing within the emerald market.
Auction Performance:
- Total revenue: $4.8 million
- Lots sold: 10 out of 13 (77%)
- Carats sold: 45,864 out of 59,192 (77%)
- Average price per carat: $105.49
Adrian Banks, Managing Director of Product & Sales at Gemfields, highlighted that the auction offered a valuable opportunity to assess current market trends. “This auction exclusively featured unsold lots from Kagem’s November 2024 higher-quality emerald auction. With the same schedules in place, we could directly compare demand and pricing, and it was encouraging to see a notable increase in bids. Despite a subdued market sentiment, the rise in demand and pricing is a positive sign for the sector,” said Banks.
The emeralds sold were mined at the Kagem mine in Zambia, where Gemfields holds a 75% stake, while the Industrial Development Corporation of Zambia owns the remaining 25%. Proceeds from the auction will be fully repatriated to Kagem, with royalties paid to the Government of Zambia based on the final sales prices.
With positive market signs emerging, Gemfields remains optimistic about the upcoming trade shows in Bangkok and Hong Kong, anticipating further recovery in the emerald market.

Paraiba Tourmalines Deposit Discovered In Ethiopia
SSEF Said Trace-Element Data From The Suspected Ethiopian Material Overlaps Considerably With Stones From Established Localities, Particularly Brazil
The Swiss Gemmological Institute (SSEF) has received credible reports indicating the discovery of a new deposit of copper-bearing tourmalines, known in the trade as Paraíba tourmalines, in Ethiopia.
The development coincides with the submission of several stones whose geographic origin proved difficult to determine using existing methods. Preliminary analyses suggest some may originate from Ethiopia.
Since their discovery in Brazil in the late 1980s, Paraíba tourmalines have been prized for their vivid “neon” blue and bluish-green colours caused by copper within their crystal structure. Additional deposits were later found in Nigeria and Mozambique, with the latter becoming a major source.
SSEF said trace-element data from the suspected Ethiopian material overlaps considerably with stones from established localities, particularly Brazil, making origin determination challenging. The institute is conducting further research to characterise the new material and refine methods for distinguishing it from copper-bearing tourmalines from other sources.
