GUNNISON CRATER TEKTITE™

Gemstone Mining and Development

Research Suggests Devonian Extinction Link

Tonko Mining Company was founded in an effort to promote the research and development of our valuable and scientifically important assets.  Presently, this is a small “mom and pop” type of operation that puts environmental concerns at the forefront of all endeavors.  Our discovery of the Gunnison Meteorite Crater was supported, in part, by the documentation of the unique gemstone Gunnison Crater Tektite™ formed naturally in the crater’s center.

Heirloom Collector’s specimen selection now available.  Please see our new Product List.
