This piece is exceptional for its structure. Distorted elongated glassy lustered crystals bisect, penetrate, twist and twin. One can see small satellite crystals as classic “poker chips” (prismatic hexagonal crystals). The seed crystals must have gone through some temperature and pressure changes as they start and stop. Different shades run in parallel to the elongated axis. A serious piece. Ex Paul Lazar and Geoff Krasnov.
