Apophyllite
About
Apophyllite is a translucent to transparent mineral that often forms with pyramidal terminations. Its name derives from the Greek words apo ("off") and phyllon ("leaf"), referring to its tendency to flake apart when heated. Found in shades of white, green, and colourless. Major sources include India, Brazil, and Mexico.
Birthstones & Anniversaries
Apophyllite is not a traditional birthstone.
Crystal Healing Energy
The overarching theme of apophyllite is spiritual connection and clarity. Apophyllite is believed to enhance intuition, promote mental clarity, and encourage a strong connection to higher realms. Its uplifting energy is thought to create a sense of peace and balance, making it ideal for meditation and spiritual work.
Facts
Water Content: Apophyllite contains water within its crystal structure, contributing to its clarity and unique refractive properties.
Basal Cleavage: Known for its perfect cleavage, apophyllite flakes easily along its crystal planes when handled roughly.
Major Sources: India is the leading producer of high-quality apophyllite, particularly from the Pune region.
Variety of Colours: Green apophyllite is particularly rare and highly sought after, while clear and white varieties are more common.

TreatmentsApophyllite is typically untreated, with its natural clarity and colour highly prized.
SyntheticsSynthetic apophyllite is not commercially available due to the abundance of natural material.
ImitationsApophyllite is not typically imitated as its not used in jewellery due to it’s hardness, and the material is also abundant and affordable.
similar materialsQuartz: Clear quartz can resemble apophyllite but is harder and lacks apophyllite’s characteristic basal cleavage.
Selenite: Similar in clarity but softer and with a fibrous texture.
Calcite: Can appear similar in crystal habit but reacts with acid and has a different cleavage pattern.
