Description

Beautiful gemmy dark green grossular crystals associated with possibly clinozoisite microcrystals.

It is very tempting to trim this specimen but there are numerous microcrystals scattered on the matrix.  Also, we have decided not to do so in order to respect the original collector's point of view, which is the study of minerals in their geologic environment.
