Natural Botryoidal Stilbite with Heulandite Crystal Cluster – 150 g

This natural Botryoidal Stilbite with Heulandite specimen features abundant cream to honey-beige botryoidal Stilbite growth covering a contrasting dark natural matrix, with prominent white to translucent Heulandite crystal formations intergrown throughout. The rounded Stilbite aggregates display a smooth to finely textured botryoidal habit, while the white Heulandite crystals show elongated and bladed forms with attractive natural luster. The combination of rounded golden-cream growth, white crystal formations, and dark matrix creates a distinctive and richly textured collector specimen.

Geological Note

Stilbite and Heulandite are zeolite-group minerals that commonly occur together in cavities and fractures of volcanic rocks. Stilbite may develop as radiating, fibrous, sheaf-like, and locally rounded or botryoidal aggregates, while Heulandite commonly forms tabular to bladed crystals. These minerals form from mineral-rich hydrothermal fluids circulating through cavities and fractures in volcanic rocks over geological time.

Please Note: Natural mineral specimens may naturally contain variations in color, crystal formation, transparency, texture, inclusions, fractures, cavities, chips, luster, and matrix. Each specimen is naturally formed and may differ slightly from the photographed piece.
