Description

Every mineral is a story of chemistry, pressure, and patience. Indian trap basalts host a staggering variety of zeolite minerals. Apophyllite forms cubic or pyramidal crystals, often colorless or pale green, perched on salmon-pink stilbite fans. The combination is one of mineralogy’s most arresting — ice-clear prisms on the warmth of stilbite.

This specimen originates from Jalgaon, Maharashtra, India, one of the world’s most significant localities for this type of material. Collectors and scientists have drawn from this region for generations, and for good reason: the combination of geological conditions here produces specimens of exceptional quality and clarity.

Every specimen is unique. Photographs approximate the visual experience, but the real thing — its weight, its luster under a raking light, the way it catches the corner of your eye — can only be experienced directly.

Formation

This specimen formed through geological processes operating over timescales that dwarf human history. The specific combination of chemistry, temperature, pressure, and time at this locality produced material of exceptional quality that makes it a valued addition to any serious collection.
