2025年3月5日 · Jalpaite is a very rare species, and only a few large crystals are known to exist. This specimen, believed to have been found around the turn of the 1900s, is a monster for the species. And, it is quite attractive!

Jalpaite (SXRD-analysed) as aggregates of dark grey, short prismatic, ductile crystals on quartz. Found by Richard Bayerl in August 2013. The matrix of the specimen consists of quartz, colourless fluorite and much strongly covellinised chalcopyrite.
