Penroseite Locality: Virgen de Surumi mine (Pacajake mine; Pakajake mine), Pakajake Canyon (Pacajake Canyon), Chayanta Province, Potosí Department, Bolivia (Locality at mindat.org) Size: 4.9 x 2.4 x 1.8 cm. Penroseite is a very rare nickel, cobalt, copper selenide and this rich and fine specimen is from the Type Locality - the Virgen de Surumi Mine of Bolivia. The famous selenium minerals from this locality have often been falsely attributed to the Hiaco mine (2km west, on the opposite flank of Pakajake canyon) or to the Colquechaca mine (28km southwest), but neither of those mines yields any selenium minerals at all. Silvery, metallic, parallel-growth blades of penroseite comprise nearly all of this very rich specimen. Accompanied by a 1950s era, faded Burminco label that has a penciled-in, August, 1951 date. Ex. Mullane Collection. Weighs 60 grams. Mineral

Pentagonite Locality: Wagholi Quarry, Wagholi, Pune District (Poonah District), Maharashtra, India (Locality at mindat.org) Size: miniature, 5.4 x 5 x 4.5 cm Pentagonite I had to pull out the thesaurus for this specimen, it is that spectacular! The three lustrous and razor-sharp Pentagonite crystals (up to 1.6 cm!) sit perfectly balanced within the vug, and they have the classic deep blue color that is so highly desired for the species and so rare in the mineral kingdom. This miniature is nonpareil, desirable and superlative. It is just an amazing piece...to have such long, gemmy crystals, and have them so immaculately protected in a perfectly-sized vug for the collector, not too big and not too small, that displays them so nicely....i mean, its ridiculous. And, its mailable, safely. Mineral
