Auction Results: Mixed-Quality Rubies

LONDON, 06 OCTOBER 2025

Gemfields is pleased to announce the results of a mini-auction of Mozambican
rough rubies from Montepuez Ruby Mining ("MRM") held via online bidding after
viewings in Bangkok, Thailand from 29 September to 3 October 2025.

Highlights: Mini Mixed-Quality Ruby Auction - September - October 2025

·    Auction revenues of USD 11.0 million

·    26 of the 33 lots on offer were sold

·    62% of the 297,449 carats on offer were sold

·    Average realised price of USD 59.43 per carat

Adrian Banks, Gemfields' Managing Director of Product & Sales, commented:

"This mini-auction primarily featured medium and commercial grades of
secondary material sourced from a recently developed mining area in the
'Maninge Nice' domain and where our processing activities have been
concentrated in recent months. We are encouraged by both the results and the
strong customer engagement, reflecting growing interest in this new material.

Seven lots-mostly representing the smallest size ranges within the same
lower-quality grade, and offered for the first time at this auction, remained
unsold. As this auction is part of the early market discovery process for new
material, we will leverage the market feedback received to refine our future
offerings."

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.

Ruby Auction Schedule Update

Gemfields has made the decision to defer the usual November/December ruby
auction to January/February 2026. This is on account of the previously advised
delay in the final commissioning of MRM's second processing plant at MRM, now
exacerbated by illegal miner action.

While final commissioning is presently still expected in October 2025, the new
plant's operation has been materially impacted during the last week by illegal
miners, who presently number between 250 and 400 per day, sabotaging the plant
supply infrastructure. In addition, the illegally mined rubies leaving the
Montepuez region has a detrimental impact on market prices and on Mozambique's
tax receipts from its ruby resources. Gemfields and MRM continue to engage
with the appropriate Mozambican governmental authorities.
