Stibnite With Calcite
Small Cabinet, 8.5 x 6.6 x 4.5 cm
Sombrerete, Zacatecas, Mexico
Ex. Richard Heck

We see very little good stibnite from Mexico, and almost nothing with "style" and aesthetics. This piece, though, has both. Stacked poker-chip aggregates in parallel growth of gray but lustrous calcite, to 2.9 cm in length, are the natural pedestal for a diverging cluster of splendent, dark gray crystals of stibnite, to 5 cm in length. This combination of species makes the piece more aesthetic than others I have seen, and we believe this to be a fairly significant locality specimen.
