About Scolecite

Scolecite is a hydrated calcium aluminosilicate zeolite mineral that typically forms delicate, colorless to white prismatic crystals with a silky vitreous luster, often arranged in radiating sprays and clusters. It is commonly found in amygdaloidal basalts and volcanic rocks in India's Deccan Plateau, Iceland, and Colorado, USA. The interplay of its translucent needles and reflective luster makes scolecite a favorite among mineral specimen collectors.
