2.8" Apophyllite Crystals on Chalcedony - Maharashtra, India

This is a cluster of lustrous apophyllite crystals on chalcedony, collected from the Deccan Traps (the world largest basalt flow) in Maharashtra, India. The red mineral aggregations are unknown, however they're intertwined with apophyllite and chalcedony formations, resulting in some vibrant inclusions that are best viewed under magnification.

This specimen comes from the Deccan Traps, a large igneous province and one of the largest volcanic features on Earth, in the Pune Province of western India. In the course of quarrying for other materials or digging wells, sometimes large pockets of zeolites and other minerals are unearthed in the volcanic rock.

Apophyllite, while not a zeolite itself, is almost always found associated with zeolites in the same pockets. It has two crystal habits: a rectangular prism capped by a steep four-sided pyramid, or a pseudo-cubic structure. While not a well-known mineral to the general public, it is popular among mineral collectors due to its pastel colors and beautiful crystal formations.
