What began in 1992 as a small gemstone workshop in the heart of New York has now blossomed into one of the most trusted names in the colored gemstone industry. Started GITL with a simple yet powerful vision – to bring ethically sourced, untreated gemstones directly from mines to collectors without compromising on quality or transparency.
Over the past three decades, we have built lasting relationships with mining communities in Colombia, Zambia, Myanmar, Sri Lanka, and Madagascar. This allows us to source the finest emeralds, rubies, sapphires, and rare crystals while ensuring fair trade practices and sustainable mining.
Today, GITL serves thousands of happy clients, designers, and investors worldwide. Every gemstone we sell is accompanied by a detailed laboratory report, and our bespoke jewelry service has helped create countless heirloom pieces that will be cherished for generations.
