Galena and DolomiteWhat 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.

Specimen # BOL711B91

but it is contacted a little on the back

The pieces from Bolivia are reminiscent of the classic and highly sought after Zambian specimens

my father collected several superb specimens from this locality

This piece must have hardened under ideal conditions as it has amazing clarity for a larger specimen

where the crystals rarely exceeded 6 mm in length

and this is one of only a few pieces that I have ever had to offer

soft yellow and white/grey color crystals of this hard-to-find species on matrix

in late 1977

or native elements

and does have some small “cogs” around the edges
