Natural Stilbite with Heulandite Crystal Cluster – 20 g

This natural Stilbite with Heulandite specimen features a striking elongated formation dominated by cream to pale honey-colored Stilbite, with broad fan-like and radiating crystal growth. The Stilbite displays fine natural striations, a delicate fibrous texture, and a soft pearly luster. Numerous white to translucent Heulandite crystals are intergrown throughout the formation, creating contrast and additional crystal detail. The unusual vertical growth and layered crystal arrangement give this specimen a distinctive sculptural appearance.

Geological Note

Stilbite and Heulandite are zeolite-group minerals that commonly occur together in cavities and fractures of volcanic rocks. Stilbite frequently forms fan-shaped, radiating, sheaf-like, or fibrous aggregates, while Heulandite commonly develops as tabular or 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.
