Gemfields Holds First Ruby Sale Since 2019 RAPAPORT... Gemfields brought in $58.9 million at its first auction of rough rubies in more than a year, expressing optimism as operations at its Mozambique mine gradually resumed. The miner held seven small sales of high-, medium- and commercial-quality goods between March 15 and April 8, noting on Thursday that its last ruby auction had been in December 2019. Viewings took place in Bangkok, Thailand, and in Jaipur, India, as well as in Dubai, followed by submissions of sealed bids through an online platform. Some 52 companies placed offers, with Gemfields selling 89 — or 95% — of the 94 lots available. By carat weight, 47% of items found buyers, it said. The average price was an unusually high $171 per carat, reflecting the quality mix of the stones that sold.
