Minerva Mine #1, Rosiclare Level, Cave in Rock
3.2 x 2.9 x 1.8 CM (thumbnail)
Late Summer 2021
Textbook perfect form and top quality Witherite crystal on matrix from the Minerva Mine. It is not often we see a super Witherite in thumbnail size, this is in perfect condition, no damage and looks fine from any angle. The form of this piece looks much like a classic English Witherite but it is from Illinois where this is a quite rare habit. There were just two important localities for fine Witherites worldwide, Cumbria in the UK and the Minerva Mine in the USA. Both locales are now classics and neither produces anything today. This piece is also intensely fluorescent.
Witherite on Fluorite
Minerva #1 Mine, Cave-in-Rock, Hardin County
2.8 x 2.6 x 1.8 CM (thumbnail)
A complete ivory colored Witherite crystal sitting on a blue crystalline Fluorite showing classic form. From the famed Minerva #1 Mine, this is a well formed thumbnail specimen in very good condition. The faces of the Witherite have the characteristic tiny stepped structures that are so definitive for this locality.
