Bustamite, Galena, Calcite
Broken Hill, Yancowinna Co., New South Wales, Australia
Small Cabinet, 9.1 x 7.8 x 5.7 cm
Intergrown calcite and massive bustamite are the matrix for prismatic, flesh colored crystals to 7 cm across, and the piece weighs about 500 grams. Bustamite is an uncommon mineral species in crystal form known best from this locality (old workings, though) and from Franklin in New Jersey. Specimens from each appear similar. The calcite even fluoresces in each case. Here, though, the galena crystals embedded in the calcite matrix give it away as Broken Hill material.
