- Beraunite With Kidwellite
- Miniature, 3.4 x 3.3 x 2.8 cm
- Coon Creek Mine (York Mine), Shady, Polk Co., Arkansas, USA
- Ex. Martin Zinn
A very rare specimen of crystallized beraunite, colorful and showy. This is exceedingly rare material in such quality! These were found just once, I am told, in the 1960s. The specimen is from a pocket which produced probably the best of species for beraunite in the US. The kidwellite, a green mineral, is a nice association and was first found in Arkansas.
