Beautiful specimen of unusually combined Mordenite and Chalcedony. Very delicate structure of sea blue colored Chalcedony stalactites. They are worm-like crystals intergrown together. Atop are grown snow-white sprays of Mordenite. They are very delicate and contrast nicely on the blue background. The specimen has very original and beautiful 360 degree display. In very good condition – some small contacts and imperfections.

Astounding!
