1.4" Chalcedony Encrusted Quartz and Chabazite Crystals - India

This is a beautiful, 1.4" wide specimen that features an association of quartz crystals and chabazite crystals that are encrusted in chalcedony, collected from Madhya Pradesh, India. This formation occurred within a cavity/vug in the basalt host rock. Apophyllite, barite, and julgoldite crystals have also been reported as being present within some of these vugs.

Chabazite is the name for a series of minerals that include chabazite-Ca, chabazite-K, chabazite-Mg, chabazite-Na and chabazite-Sr. The variety of the crystal is dependent on the cation present during formation (Ca, K, Mg, Na or Sr). The red chabazite is commonly a calcium dominant variety (chabazite-ca), the most prevalent of the chabazite series. Crystals usually exhibit a rhombohedral habit and can display a variety of colors including red, orange, yellow and colorless.

The general chemical formula of chabazite is (Ca,K2,Na2)2[Al2Si4O12]2 · 12H2O .
