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 at the Unificada mine in Potosi. It features dozens of exceptionally rare, translucent, incredibly beautiful green color (with a slight iron coating), euhedral "butterfly"-twinned crystals measuring up to 11 mm of this great phosphate on matrix. Very few specimens seem to have been found.
