This November, Gemfields proudly celebrates its 50th auction of Kagem emeralds, marking a significant milestone in the coloured gemstone industry.
Gemfields transformed the international gemstone market with its pioneering auction process, launched in 2009. This innovative approach has brought transparency and a steady, reliable supply to an industry previously limited by inconsistent and fragmented availability.
The auctions have evolved over time, but the core tender-style system has remained unchanged. Gemfields has actively adapted its approach to maintain a sustainable supply of gems in response to changing market conditions. Examples of these developments include extending the viewing period to give customers ample time to inspect the lots in a comfortable environment and the introduction of an electronic bidding system.
Appreciation for Zambian emeralds has also increased exponentially since the introduction of the auction system. Zambian emeralds are prized for their deep, rich green colour with bluish undertones, which sets them apart from emeralds found in other regions. Known for their excellent clarity and durability, these emeralds often contain fewer inclusions than others, making them visually appealing and versatile for jewellery manufacture.
Previously seen as secondary to Colombian emeralds, Zambian cut gemstones now stand alongside their Colombian counterparts in several categories, often at comparable price points. Gemfields is proud to have played a central role in this transformation, and with deep gratitude to its customers, the company looks forward to the 50th Kagem emerald auction taking place this month.
