RDN33 Hutchinsonite
Quiruvilca Dist., Santiago de Chuco Prov., La Libertad Dept., Peru
19.5x 9.7x 8.5 cm

An rich specimen of this rare thallium bearing mineral, hosting numerous elongated bright crystals scattered around a large matrix.  The crystals are somewhat camouflaged against their matrix, but when you hold the piece in person you will see a lot of them.

Most of the hutchinsonite specimens in collections were recovered from this locality in the 70's and 80's (many had the crystals occurring on orpiment), though over the last 2-3 years I have intermittently seen examples from more recent workings.  

Hutchinsonite is a sulfide of thallium, lead, and arsenic and is probably one of the few minerals containing thallium that you can actually find a decent specimen of.
