Calcite on Sphalerite
Availability: 1 in stock
Bright gemmy amber scalenohedrons populate the surface of massive sphalerite. Some cleaved crystals knocks this one off the top tier. Hard to find anything of this quality from the 1980’s workings. I purchased this piece in 2005.
Locality: Minerva #1 Mine, Cave in Rock District, Hardin County, Illinois
