Gemfields Showcases 36-Carat Ruby and Expands Offering at June 2025 Auction
Gemfields announces that it will offer a broader range of secondary-type material at its forthcoming mixed-quality ruby auction in June 2025. The auction will include rubies recovered from a newer section of its Mozambican mine that has not previously been represented at auction in meaningful quantities and with a notable 36-carat ruby forming part of the offering.
The gems, from the newer section, often display a slightly lighter tone and stronger fluorescence, due to lower iron content, offering customers an opportunity to broaden their range of tones and hues.
Gemfields has built a strong reputation for the reliable and consistent supply of Mozambican rubies through its well-established auction platform, which sees the full sales proceeds of each auction repatriated to Mozambique. Its structured and transparent sales system has ensured dependable access to a wide range of ruby qualities, allowing manufacturers, jewellers, and brands to plan their supply chains with confidence.
Adrian Banks, Managing Director for Product and Sales at Gemfields, says, “It is exciting to see the evolving variety of rubies being recovered by Montepuez Ruby Mining. I am particularly eager to see how a single fine-quality ruby weighing 36 carats will perform at our auction. I believe this ruby will be strongly contested by discerning clients who recognise the rarity and significance of such a gemstone, given both its size and quality.”
Looking to the future, the forthcoming completion of a new 400 tonne-per-hour ore processing plant, tripling MRM’s through-put capacity, will be a significant development. This increased capacity will be crucial in maintaining Gemfields’ ability to provide a steady supply of a wide-ranging portfolio of Mozambican rubies, in order to meet the expectations of the market.
