Abstract

Part of the 2006 industrial minerals review. During 2006, total U.S. gemstone trade with all countries and territories exceeded $28.3 billion. Estimates indicate that U.S. gemstone markets accounted for over 35 percent of world gemstone demand in 2006. Natural gemstone production from U.S. deposits during 2006 was worth an estimated $13.3 million, a slight decrease from 2005, and included agates, amber, beryl, coral, garnet, jade, jasper, opal, pearl, quartz, sapphire, shell, topaz, tourmaline, turquoise, and many other gem materials. Laboratory-created gemstone production in the U.S. was worth an estimated $47.4 million, a 7 percent drop compared to 2005 production.
