Description

One of the finest samples of orange-red jeromite on a single rock crystal we've had so far.

There are only 5 localities worldwide where this mineral was found and this is by far the best. In the moment jeromite is discredited as a species, but we hope that someone is working on it. Described as "an amorphous As-S-Se phase of variable composition".

Poisonous because of its high arsenic content.
