Green Cuprian Powellite (Chile!)

Item Description

This is a very rare specimen of a new varietal of cuprian powellite that was identified during analysis of the szenicsite associations from this remote mine, only found in the 1990s by Terry Szenics. I bought much at the time, and to my knowledge, no more of this material has been found since then. Most of the gemmy and lustrous crystals are a beautiful apple-green, with fewer, darker green. Bright yellow fluorescence, as you would expect from powellite
