Description

Very rare to find locality specimen of apophyllite with a nice porcelain white colour, with minor volcanic matrix. The crystals have pyramidal terminations {101}, with the prism {110} scarcely developed, and only present as a rhombic face. The terminal (001) face is scarcely developed or typically absent, so the ends are very sharp. Good representative specimen that I collected on October/3rd/2023 (second picture).

This piece is the second apophyllite from Gruevo ever offered on e-rocks.
