Prehnite Specimen

Prehnite is a calcium aluminum silicate mineral typically found in cavities and fractures within volcanic rocks. It commonly forms rounded, botryoidal masses, but can also develop distinctive radiating aggregates of small crystals.

This specimen displays pale yellow-green to green prehnite in densely clustered, fan-like formations, with individual radiating structures visible across both sides of the natural matrix.
