Prehnite cast after Calcite (uncommon old locale)

Item Description

Prehnite specimens are uncommon from this old obscure South African locale and this is a dramatically sculptural large example. Frosted, translucent, pretty mint-green, bladed crystal aggregates that formed as casts after calcite rhombs compose this impressive piece. The stalactites really add pizzazz. The back or base is very flat, indicating that the piece grew against a large sharp crystal. The left side with the stalactites is very 3-dimensional. Excellent and rare in this quality large material. A fine example from the small lot we obtained.
