This specimen is from Maharashtra, India. Its main minerals are stilbite (the flattened crystals at the base) and thompsonite (the massive sprays at the top).
The first photo was taken under long wave ultraviolet lighting. The photo below was taken under short wave ultraviolet lighting. The specimen shows best under a combination of both lighting conditions. The thompsonite fluoresces white under UV lighting. The blue to purple is the UV lighting reflecting off the non-fluorescing stilbite crystals.
