The auctions, which took place in Thailand from 3-18 June, comprised mixed-quality rough gemstones, with 97 per cent of lots finding buyers.
The company achieved $USD68.7 million ($AUD103.5 million) from the sale of 94 lots from the Montepuez mine in Mozambique, with rubies selling at more than $USD300 ($AUD452) per carat for the first time.
Managing director of product and sales, Adrian Banks, said that while it was important to be mindful of context when comparing auction results, the outcome was positive regardless.
“We are pleased to announce another strong result,” Banks said.
“While auction results should not be directly compared, our team is proud to have crossed the milestone of an average selling price of $USD300 per carat at this auction.”
Gemfields sold 216,600 carats of rubies at an average price of $USD317 ($AUD477) per carat. An average of $USD290 ($AUD437) per carat was achieved at the previous ruby auction in November-December.
The company has recorded $USD1.12 billion ($AUD1.16 billion) across 22 Montepuez ruby auctions since 2014.
Former De Beers Group CEO and co-chair Bruce Cleaver was recently appointed chairman of Gemfield’s board of directors.
