Natural Prehnite 45.6ct Oval Cabochon

A large oval with an even, pale yellow-green body and a consistent scatter of black needle inclusions distributed uniformly from edge to edge, with no strongly clear zones or heavy concentrations. The regular, balanced patterning gives this stone a steady, predictable character across the surface, with the needles fine enough not to break up the base color significantly. High-gloss polish.

The consistent epidote distribution in this piece is typical of African prehnite that formed in a uniformly inclusion-bearing crystal environment. Prehnite is always untreated. At 34.6x20.5mm this large oval suits substantial pendant and brooch settings.
