This long, slender beryl crystal is blue enough to be considered an aquamarine, although its hue has a significant greenish cast. It has a distorted hexagonal cross section, with a natural contact termination at one end, and basal cleavage and fracture at the other. The crystal is quite transparent, with a few dark inclusions and a series of basal internal fractures that display as a dozen white zones when the crystal is illuminated with a bright light. The clarity of the crystal is marred by striations running the length of the crystal, leaving only a few thin windows through which one may examine the interior. Other than the fracture at one end, the only dmage is a fracture near the base where the specimen was removed from its host rock. There are a number of contact points and small pits where more of the host rock was removed, leaving small (often dirty) cavities.
