110 ct Blue Gem Turquoise Cabachon (#13)

Natural Turquoise Cabachons 2" x 1 1/4" This is a monster piece of super high-grade natural Blue Gem turquoise.  The Blue Gem mine near Battle Mountain, Nevada was long ago pulverized and processed for copper and other precious metals, so turquoise from this location is no longer available.  This extremely hard stone was cut and polished by the DePriest family of Manassa, Colorado in the 1970s.  We bought a collection from Gary DePriest in the 90s and finally decided it needs a new home.  This baby has waited far too long to have its natural beauty and unique character exposed. We offer a 100% satisfaction guarantee on every purchase.

An extensive breccia zone about 10 feet wide is developed between the two bounding sheers. Exceptionally good quality turquoise forms veins u
