This thumbnail specimen of matrix has RELATIVELY HUGE, robust balls of dark matte green Greifensteinite rising from its top. While not the prettiest rarity, it is a very significant example for its own species and highly thought of. It comes with a copy of a letter from Dr. Vandall King saying it is the best he knows of (as a specialist in Maine minerals), and that finer had not been seen.
