Adrian Banks’ Comments on Auction Success
Adrian Banks, Gemfields’ Managing Director of Product & Sales, commented: “We extend our gratitude to all participants who contributed to making this five-day auction both successful and enjoyable. This auction can be described as a hybrid offering, featuring both primary and secondary rubies. Over 90% of the secondary material was under 0.2 grams (1 carat), presented across 13 lots and spanning a broad range of qualities. The primary rubies offered were of commercial quality, predominantly in smaller sizes. Only one lot remained unsold – a 13.6kg parcel of ‘L2’ quality, weighing between 0.05 and 0.09 grams (0.25-0.45 carats), expected to yield small, mixed-colour sapphires after cutting and polishing. This parcel, the largest by weight, accounted for 27.2% of the total weight offered. The auction saw strong attendance and robust demand, providing a timely affirmation of the state of the ruby market against the backdrop of tariff-induced uncertainty in global markets. We extend our thanks and congratulations to the Government of Mozambique and our partners at Mwiriti, both of whom attended, on achieving very healthy results for material of this size and quality.”
Auction Proceeds and Royalty Payment
The gemstones were extracted in Mozambique by Montepuez Ruby Mining Limitada (“MRM”), which is 75% owned by Gemfields and 25% by Mwiriti Limitada. The proceeds of this auction will be fully repatriated to MRM in Mozambique, with all royalties due to the Government of the Republic of Mozambique being paid on the full sales prices achieved at the auction.
