Ruby Auction Results

LONDON, 21 JUNE 2023

Gemfields is pleased to announce the results of a ruby auction comprised of mixed-quality rough rubies held during the period 5 - 20 June 2023.

Highlights: June 2023 Mixed-Quality Ruby Auction

·    Total auction revenues of USD 80.4 million

·    91 of the 94 lots offered for sale were sold (97%)

·    Average realised price of USD 265.99 per carat

·    The 19 auctions of Montepuez Ruby Mining Limitada's ("MRM") gemstones held since June 2014 have generated USD 978.5 million in total revenue

·    One lot of 26.8kg (representing some 30% of the total weight offered) remained unsold. As a result, the average price per carat realised at this auction was considerably higher than it would have been had this lot also been sold.

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

"With the revenue from this auction up 20% since our last ruby auction in December 2022, today's results echo the significant rebound in market prices we reported just weeks ago for Zambian emeralds. The ruby market is clearly firing on all twelve cylinders and the step-change in market pricing which we reported in 2022 is notably enhanced. As always, we send our thanks and congratulations to our hard-working teams, our partners, our host governments and of course our clients for their support."

The auction lots were made available in Bangkok for private, in-person viewings by customers. Following the viewings, the auctions took place via an online auction platform specifically adapted for Gemfields and which permitted customers from multiple jurisdictions to participate in a sealed-bid process.

The rough rubies were extracted by MRM (which is 75% owned by Gemfields and 25% by Mozambican partner 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 price achieved at the auction.

The results of the five most recent mixed-quality MRM ruby auctions are summarised in the table below (and earlier results are available at www.gemfieldsgroup.com):

Average per carat sales value	USD 171.33/carat	USD 132.47/carat	USD 246.69/carat	USD 154.84/carat	USD 265.99/carat

* One lot of 76,343 grams (representing some 53% of the total weight offered) remained unsold at the March/April 2021 auction. As a result, the average price per carat realised at this auction was considerably higher than it would have been had this lot also been sold.

** One lot of 26,806 grams (representing some 30% of the total weight offered) remained unsold at the June 2023 auction. As a result, the average price per carat realised at this auction was considerably higher than it would have been had this lot also been sold.

The specific auction mix and the quality of the lots offered at each auction vary in characteristics such as size, colour and clarity on account of variations in mined production and market demand. Therefore the results of each auction are not always directly comparable.
