I am a gem miner and cutter dedicated to producing natural, unenhanced gemstones. In addition to the stones we collect from our own mines, we work with other miners around the world that are also dedicated to fair trade. Tourmaline, sunstone (labradorite), opal, turquoise, variscite, and citrine are among the stones that we produce in the USA. We also specialize in Peruvian blue,green and pink opal and Mexican fire opal. In addition to our Peruvian opals we also work extensively with natural color green and blue (gem silica) chalcedony from central Peru.; http:/www.outofourmines.com/
