Historical & Geological Background:
Prehnite is a calcium aluminium silicate mineral that typically forms in low-grade metamorphic and hydrothermal environments, often in cavities within basaltic rocks. It is commonly associated with minerals such as zeolites and quartz.

First described in the late 18th century, prehnite was named after Colonel Hendrik von Prehn, a Dutch mineral collector. It is valued by mineral collectors for its soft green colour and translucent appearance, which can sometimes display a chatoyant “cat’s eye” effect.
