Kosnarite, Albite
Jenipapo district, Itinga, Jequitinhonha valley, Minas Gerais, Southeast Region, Brazil
Thumbnail, 2.0 x 1.5 x 1.5 cm
A rich thumbnail specimen (one of the best thumbs, in fact) with the top completely covered by a mat of sharp kosnarite crystals. Minor zanazziite, as well. Horrible pic, I know. A bit better in person 2 x 1.5 x 1.5 cm
