The Patch Mine near Central City in Colorado is one of the most classic localities on the front range. Gilpin County is the site of the first discovery of Gold in Colorado, and the Patch Mine (often referred to as the Glory Hole Mine) is a still standing landmark just southwest of Central City. This piece is filled with classic, sharp, lustrous, water-clear, colorless scepter Quartz crystals associated with black tetrahedral Sphalerite crystals on massive Quartz matrix. Colorado collectors will tell you that obtaining specimens from Gilpin County is very difficult because the vast majority of the mining took place before WWII and good pieces simply are not around.
