This is a fantastic cluster of massive phenakite crystals. The largest crystal is 3.3 cm across. Phenakites this size are exceptionally rare. There are three smaller phenakites on the backside of the massive one. Phenakites from this mine tend to be rather cloudy, but these are rather transparent. It has a contact at the bottom of the large crystal where it attached to another crystal. It has some embedded mica crystals. Fantastic piece. 25.8 grams.
