GEMSWORLD | 56 | 2024 MARKET INTELLIGENCE 市场情报 A new mine-to-market branding venture of a rare precious resource – unheated cornflower blue sapphires – is a cause for excitement in the gem world, particularly among high-end jewellery retailers and designers in the US. Yogold Sapphires are becoming the darlings of jewellers not just for their value factors of colour and natural clarity but also for the nostalgic punch they pack. The sapphires hail from an old famous source, the Yogo Gulch igneous dyke near Utica, Montana in the US, discovered in the 1800s during the country’s gold rushes. During its heyday in the 19th and early 20th century, the mine is reported to have produced millions of carats that were set in engagement rings and bridal jewellery. Designers at Tiffany & Co had a special fondness for the stones, which added to their popularity. But to the disappointment of sapphire lovers, mining ended in the 1980s, the result of a bankruptcy filing by Intergem, the operator at the time. The mine remained fallow for more than four decades until 2019 when the rights to the mine were acquired by a mining and geology entrepreneur, Jay Edington. With his sons Jerod and Ryan, Jay set up Yogold USA Corp in order to mine, cut and market the sapphires. Market reentry Yogold is currently implementing phase one of a threephase mining plan focused on controlled and orderly expansion over the next five years. Company president Jerod shared, “At present, we are concentrating on supplying demand in the US, particularly in the state of Montana where most of our current polished production is sold.” The miner recently entered a semi-exclusive sales and marketing agreement with Riddle’s Jewelry in Rapid City, South Dakota.
