Vibrant Blue Cavansite / Pentagonite Cluster with Phosphorescent Calcite Crystals on Druzy Stilbite Over Basalt Matrix clear green fluorite trace Pb or rare earthBeautiful blue Cavansite pentagonite radiating crystal cluster on a bed of tiny stilbite crystals that are atop basalt matrix. Also present is calcite that has a bright white color as well as green phosphorescence under 365nm long wave ultraviolet light. A cluster featuring both Cavansite and Pentagonite is a highly desirable and relatively uncommon association, most famously from the Deccan Traps region of India. Cavansite typically forms vivid
