Coloradoite & Native Gold - Bessie G Mine, La Plata County, Colorado

Description

Coloradoite & Native Gold - Bessie G Mine, La Plata County, Colorado.
Incredible specimen of coloradoite from the historic Bessie G Mine way high up in the La Plata Mountains. These specimens are not just small amounts of Coloradoite in rock as typical from this locale, but highly concentrated massive forms of this extremely rare telluride mineral. Contains micro native Gold crystals on the backside and perhaps other tellurides. ** Please note that coloradoite is a toxic mineral as it contains high concentrations of mercury. The chemical formula for coloradoite is simply HgTe, or Mercury and Tellurium. **
