Icy Azalea - Green Apophyllite on Chalcedony from Pune, India

This pocket was discovered at basalt construction site in Pune, India. It is a Green Apophyllite with various associations. Stilbite, Heulandite, and Micro Calcite. The Micro Calcite is UV reactive and Phosphorescent. 

The Apophyllite features Crenelated formations. This happens when there is a sudden stop in growth in the pocket, which is due to changes in the environment. This caused the Apophyllite to form micro points over and over again, causing the jagged looking edges. We call this formation Crenelated. 

The Apophyllite has a beautiful minty hue. Hematite Inclusions also give some of the specimens red hues.
