Apophyllite
Main Deposits
Apophyllites can be found in the USA, Brazil, Russia or South Africa, although the most famous specimens worldwide are those from India in the Poonah district.
Description and Characteristics
Apophyllite is not a single mineral, but rather a group of hydrated potassium, calcium, and fluoride/hydroxide phyllosilicates typically found in the cavities of basaltic rocks and low-temperature volcanic zones. It belongs to the tetragonal crystal system and is notable for its very intense pearly luster on its exfoliation faces, forming pyramidal crystals or rectangular prisms that are often found associated with zeolites; its structure is so sensitive to heat that, when heated with a blowtorch, it loses water and exfoliates into white sheets, a characteristic that gives it its name.

New-Age Properties
Apophyllite is a powerful energy conductor that acts as a conscious bridge between the physical and spiritual realms. It facilitates access to the Akashic Records and maintains grounding during out-of-body experiences, ensuring a smooth transfer of information.
