Description

I acquired this piece a number of years ago for my own collection. It is a large, top quality specimen with beautiful intense green, lustrous and transparent apophyllite crystals to 3.5 cm. The terminations to the apophyllite crystals are unusual as some are pyrimidal while others flat. The largest crystal is doubly terminated with the different types at each end. The numerous snow white stilbite sheaves mostly stand proud of the matrix to produce an overall stunning display piece.

Exellent condition. Originally from the Armin Wendland collection.
