Digger Glass

Digger Glass or Jeremy SinkusI was a mineral and fossil dealer and used to dig crystals around the county in the late 90’s and early 2000’s. At the Quartz Mining competition in Mt. Isa Arkansas in 1998, my "Diggerite" glass tourmaline has been recognized and analyzed by the “gem laboratory of Great Britain“ and published in the “Journal of Gemology” and “Rocks and Minerals” Magazine. Digger Glass is often invited to display as a guest exhibitor at the Tucson Gem and Mineral Show. Did you know tourmaline is classified as a “borosilicate mineral?”
