Description

A significant, non-micro specimen with an association of exotic sulfosalts on barite-pyrite-sphalerite ore. Andreadiniite occurs as black metallc crystallizations up to 2 mm long (yellow arrow) while protochabournéite is the larger, scaly mass (red arrow). Both specis are exclusive of the locality. Individually analyzed specimen by single-crystal XRD at Pisa University.

Andreadiniite is a unique assemblage of elements and has been found in very few specimens. This is arguably the best offered so far.
