This specimen is from a brand new find for the species in the Machacamarca mining district in Bolivia. It is not from the typical locality - the Unificada mine in Potosi. It features several exceptionally rare, translucent, incredibly beautiful green, euhedral "butterfly"-twinned crystals of this great phosphate. It is a very rich specimen from a very exciting new find, which hopefully could one day produce specimens of the same size and quality as those from Unificada.
