The original very aerial and stalagmitic Enargite crystals have been entirely pseudomorphed by Sphalerite crystals that in turn have been partially covered by white Smithsonite crystals, as well as small disseminations of Galena and Cuprite. How capricious mineral paragenesis can be!
Considering its complexity, the specimen has been analyzed, and the analytical report will be sent to the buyer.
This specimen comes from the collection of Michel Perraudin who, as can be seen in the images, had it wrongly identified, which is no surprise as it is a piece that begged for a very precise analysis, since its visual appearance did not indicate what it finally turned out to be.
