About Us
Global Mark Gemstones — the best gemstone shop in Dubai for certified loose stones — has been a leading miner and cutter of fine gemstones since 1980. Based at the source of one of the world's most exciting gem producing areas, we are in the enviable position to be able to select out the very best rough crystals as they come out of the mines.
With almost half a century in the industry, in-house cutting center and master cutters, close connections with mine owners in East Africa, and long experience running colored stone mines, we offer a vertically integrated service from the mine to the end consumer.
