Calcite with Sphalerite
specimen number:
8611363
location:
Blackstone mine, Shullsburg, Lafayette Co., Wisconsin, USA
description:
Colorless glassy mostly gemmy rhombohedral crystals of calcite measuring to 5.0 cm in size set nicely on a black crystallized sphalerite matrix. Slight chipping is present, this still in nice condition for this old Wisconsin classic. The areas with chipping are shown up close in the video, I do think these quite minimal.
Size: 11.0 x 7.0 x 5.0 cm (cabinet)
