Gemfields Group Limited, the world-leading miner and marketer of colored gemstones, has announced the outstanding results of its recent ruby auction, reinforcing the continued strength of the ruby market. The auction, which took place from November 20 to December 5, 2023, featured mixed-quality rough rubies extracted by Montepuez Ruby Mining Limitada (MRM), a company in which Gemfields holds a 75% stake.

Financial Triumphs in Ruby Market

The December 2023 auction showcased remarkable financial success, with a total auction revenue of USD 69.5 million. All 97 lots, comprising a total of 239,591 carats, were successfully sold, achieving a 100% sales rate. The average realized price per carat stood at a robust USD 290.02

.

This auction’s triumph contributes to Gemfields’ total auction revenue for 2023, reaching an impressive USD 242 million, marking the second-highest in the company’s history. Notably, this achievement also propels Gemfields past the significant milestone of USD 2 billion in cumulative emerald and ruby auction sales, a testament to the company’s sustained success and commitment to the industry.

Adrian Banks, Gemfields’ Managing Director of Product & Sales, expressed enthusiasm for the results, stating, “We’ve seen ruby prices at our auctions go from strength to strength in recent years, and our final auction of 2023 has further endorsed that trend. This auction has shown that the demand and pricing for rough rubies are decidedly healthy.”

Auction Overview and Process

The rough rubies auctioned were extracted by MRM, with the proceeds fully repatriated to Mozambique. All royalties owed to the Government of the Republic of Mozambique were promptly paid based on the full sales price achieved at the auction.

To facilitate the auction process, the rough ruby lots were made available for private, in-person viewings in Bangkok. Subsequently, the auctions unfolded via an online platform, specially adapted for Gemfields, allowing participation from customers across multiple jurisdictions through a sealed-bid process.
