Galena and Dolomite Childrenite Quartz of this quality is

Quartz of this quality is not usually seen from any locality in Colorado

The stacked appearance of the crystals

and it belongs to the only group of minerals that form naturally “round” or “cylindrical” crystals

I must stress that the Wavellite crystals are also very gemmy

Galena and Dolomite Childrenite Quartz of this quality isWhat an eye catching sulfide association specimen from the Black Cloud mine. The Galena crystals are essentially cubic in habit but show a slight amount of what I would describe as being slightly built up with minor stepped faces almost resembling "Cathedral Gothic" Pyrite. Associated with the Galena one can see beautiful snowball esque groups of intergrown vitreous, cream colored Dolomite rhombs. The matrix is a mix of Sphalerite, Pyrite and Galena.
