A piece of botryoidal arsenic, this one has good luster, but also seems to have a bit of dirt or rust in the crevices-- the pictures show this well.

Although not particularly flashy, these specimens are probably the best native arsenics to come from Peru—and they certainly represent a significant occurrence of the species, being every bit as good as the classic German or Czech pieces.  Of course these days, it is extremely rare to see such large plates of solid arsenic from the old localities.

 These were found within the last year and a half—I had actually heard about them before my last Peru trip, but none of the people I met there had any available.  I finally managed to track some down recently, so here they are…. With that said, I imagine they will be slow sellers, but as cool as they are, I had to find some. 

 This piece displays good botryoidal from, and when viewed from the side you can see the many layers that make up the specimen.
