Ex. E. Morales from J. Minette (mine manager at the time), November 1983

An extremely interesting specimen with double terminated Colemanite crystals perched on the sides and tops of agregates of Calcite crystals forming stalactic growths. The Calcite is a beige color with a hint of green and the Colemanite are clear to white (more clear in person than the pictures indicate). The specimen is glued to the stryofoam base of a perky box which is a very good idea considering the delicacy of the specimen not to mention keeping it free of dust.

Condition: Excellent

Flaws: Nothing Appreciable
