One of the mineral world's most dramatic and coveted color combinations: a museum-grade, electric-blue cavansite rosette on a crystalline heulandite matrix with stilbite. From the legendary basalt quarries of the Pune district in Maharashtra, India, this large cabinet piece features a prominent, centered spherical "ball" of radiating cavansite crystals.

The cavansite exhibits an astonishing, hyper-saturated cerulean to neon-blue coloration that seems almost unnatural against its host rock. This vibrant blue rosette rests like a solitary jewel atop a broad, circular plate of microcrystalline, creamy-white heulandite, which provides a stunning, high-contrast background that glitters intensely under light. Top-quality cavansite with such intense color and centralized placement is scarce, making this a prized acquisition for serious collectors and a breathtaking natural sculpture for display.
