Gemfields’ September Auctions Bring Mixed Results

Its commercial-quality sapphire, corundum, and ruby sale yielded “healthy” results, while its emerald auction was weaker than expected.

Gemfields’ commercial-quality sapphire, corundum, and ruby auction brought in $2.3 million, and its commercial-quality emerald auction garnered $10.8 million.
London—Gemfields has reported results for two commercial-quality gemstone auctions that took place in September—one for sapphire, corundum, and rubies, and another for emeralds. 

The auction offering predominantly commercial-quality sapphire, corundum, and commercial-quality rubies brought in $2.3 million. In 2023, this sale brought in $1.5 million, the miner said. 

It was 100 percent sold by lot, with all 10 lots—comprising 5.7 million carats—finding buyers.  

The sale generated an average price per carat of $0.41. 

The material was extracted by Montepuez Ruby Mining Limitada (MRM), which is 75 percent owned by Gemfields and 25 percent by Mozambican partner Mwiriti Limitada. 

The majority of the auction’s offering consisted of corundum and sapphire, which are considered by-products of MRM, said Adrian Banks, Gemfields’ managing director of product and sales. 

“We extend our gratitude to the auction participants who made this brief, three-day auction such an enjoyable event,” said Banks. 

“Despite the commercial nature of these goods, the auction saw strong attendance and robust demand. The significant volume of the lower-priced rough sold will support the factories in the cutting centers of Chanthaburi, Thailand and Jaipur, India.” 

Banks also congratulated the Government of Mozambique and Gemfields’ partners at Mwiriti, both of whom attended the auction, on “very healthy results for material of this quality.” 

The auction was held Sept. 2-4.  

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, according to Gemfields.

Gemfields’ commercial-quality emerald auction brought in $10.8 million. 

A total of 4 million carats were offered at the sale, which was 61 percent sold by weight and by lot, with 28 of the 46 lots finding buyers. 

Gemfields said it withdrew the remaining 18 lots totaling 1.6 million carats because the bids placed for those lots did not meet the minimum amount the company was willing to accept.   

In a statement shared with National Jeweler, the mining company said, “Gemfields remains committed to acting responsibly by withholding auction lots when fair market prices are not achieved, as is demonstrated by the lots we withdrew from our auction, which comprised both considerable volume and value. 

“The withdrawn lots did not reach the reserve prices following bids being placed.”  

The sale generated an average price per carat of $4.47. 

The previous commercial-quality emerald auction, which took place in March, garnered $17.1 million, recording an average per-carat price of $4.45. 

It was 92 percent sold by weight, with 40 of the 43 offered lots sold.  

The miner notes auction results are “not always directly comparable,” as the lots offered vary in size, color, and clarity on account of variations in mined production and market demand. 

Banks said the luxury-good, diamond, and gemstone markets are experiencing “distinct headwinds” due to conflicts, elections, economy uncertainty in China, and broader economic turbulence. 

“Today's overall result is weaker than expected, exacerbated in part by a competing emerald producer scheduling their own auction to finish in early September 2024, in the middle of ours, and selling through their emeralds at what customers reported as low prices,” said Banks. 

He added, “We hope that market conditions improve as we work towards the auction of higher-quality emeralds scheduled for November 2024.” 

The material on offer was sourced from its Kagem emerald mine in Zambia, which is 75 percent owned by Gemfields and 25 percent by the Industrial Development Corporation of Zambia. 

The auction was held Aug. 27 to Sept. 13, taking place via an online auction platform specifically adapted for the miner that permits customers from multiple jurisdictions to participate in a sealed-bid process. 

Prior to the sale, the auction lots were made available for private, in-person viewings by customers in Jaipur, India. 

The 49 auctions of Kagem gemstones held since July 2009 have generated more than $1 billion in revenue. 

The proceeds of this auction will be fully repatriated to Kagem in Zambia with all royalties due to the Government of the Republic of Zambia being paid on the full sales prices achieved at the auction, according to Gemfields.
