Natural Apophyllite with Heulandite and Stilbite on Matrix – 130 g

This natural Apophyllite with Heulandite and Stilbite on Matrix specimen features translucent pale green to mint-green Apophyllite crystals intergrown with white to cream Heulandite and Stilbite formations. The specimen displays a complex combination of crystal habits, including blocky to prismatic green crystals, elongated white fibrous growth, and smaller peach-toned mineral formations across a contrasting dark matrix. The varied colors, crystal forms, and dense natural growth create a distinctive and richly textured collector specimen.

Geological Note

Apophyllite, Heulandite and Stilbite commonly occur together in cavities and fractures of volcanic rocks. Apophyllite may form clear to pale green translucent crystals, while Heulandite commonly develops as tabular or bladed crystals and Stilbite forms radiating, fibrous, or sheaf-like aggregates. These minerals form through mineral-rich hydrothermal fluids circulating through volcanic rock cavities and fractures 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.
