Description

Dominating the specimen, a well-developed twinned whewellite crystal stands out by its size and transparency, accompanied by several smaller crystals of the same mineral.

The main crystal shows a prismatic morphology with well-defined faces, displaying slightly satin to vitreous surfaces with a cream-white to faintly yellowish coloration. Its structure exhibits sharp edges and triangular to prismatic faces, typical of whewellite crystallization.

The mineral occurs on a dark, finely crystalline matrix, creating a strong contrast that highlights the transparency and geometry of the main crystal.
