Witherite - classic USA (Ref: AC-309)

Choice, old (1960 vintage) cluster of two main Witherite crystals with minor Calcite and Fluorite on the back. The larger crystal is about 6 CM across, quite large for the specie. The front, or display side, is in good condition, the back right rear edge is cleaved but still displays well. The top crystal is more complete and even though smaller is the focal point. The larger lower crystal is less complete due to cleaves but makes a nice base for the upper. This is vividly fluorescent in all wavelengths, and the crystal terminations show the classic rounded step-type structures. The prism faces have the small stair-step structures that are classic for the specie. Witherite was fairly common in the early years of mining in the Fluorspar region, but really good specimens were rare, and since they were not colorful very few were saved. These now rank as some of the very best ever found on earth. I am told there is no longer any locality in the world where any is being found, and certainly not large fine crystals like these. A very good modern classic.
