Spherulitic Rhyolite Display Specimen — 963 g

An individual display specimen of spherulitic rhyolite, showing a vivid geological palette of moss green, olive, smoky grey and iron red, punctuated by pale cream spherulites.

This substantial piece preserves the visual language of a volcanic flow in miniature: rounded spherulites, green altered matrix, red iron-rich zones and dark mineral seams crossing the stone. Spherulites are radial mineral growths formed as silica-rich volcanic material cooled and crystallised.

Presented as a natural rough/cut geological specimen, this is the exact one-of-a-kind piece pictured. Its irregular edges, seams, fractures and variations in surface texture are natural features of the stone. Photos taken while rhyolite was wet
