Heulandite

This heulandite formed in cavities within volcanic rock, where mineral-rich fluids slowly crystallized delicate, glassy crystals along open surfaces. The Toutle River area, shaped by volcanic activity in the Pacific Northwest, is known for producing attractive zeolite minerals like heulandite.

Light, lustrous, and often arranged in elegant clusters, this specimen reflects the quiet mineral-forming processes that follow volcanic events, preserving crystal growth within ancient lava flows.
