Ex. Al Ordway
A sharp crystal of this rare sodium-magnesium sulfate. It does need to be oiled with mineral oil to preserve its hydration state, if in a humid environment. This is a great piece, for quality and symmetry! Initially the color looks dark gray, but when backlit it goes mostly white and transparent. An excellent example of this very rare species, self-collected by Al Ordway over many trips to this locality.
