Apophyllite is a mineral group rather than a single species, best known for its bright, reflective crystal faces and exceptionally high light transmission. It is often immediately recognizable by its glassy luster and natural sparkle.
The name Apophyllite comes from the Greek words apo (away) and phyllon (leaf), referring to the mineral’s tendency to flake or exfoliate when heated — a property noted by early mineralogists.
Apophyllite most commonly forms as well-defined prismatic or pyramidal crystals, often with a square or rectangular cross-section. These crystals frequently grow in clusters and are commonly associated with other zeolite minerals such as Stilbite, Heulandite, and Chalcedony.
Major sources of Apophyllite include India (particularly the Deccan Traps), Brazil, Mexico, Iceland, and parts of Germany.
Apophyllite belongs to a group of hydrated potassium-calcium silicate minerals. It commonly forms in volcanic basalt cavities where mineral-rich fluids slowly crystallize under stable conditions.
Crystals grow with strong cleavage in multiple directions, which is why Apophyllite often displays extremely flat, mirror-like faces. These planes reflect light efficiently, giving the crystal its distinctive luminous appearance.
Apophyllite can occur in several color varieties, including clear/colorless, white, green, peach, and yellow. Color variations are influenced by trace elements and growth conditions.

⚠️ Handling:
Apophyllite has perfect cleavage and can chip or flake easily. Handle gently, especially clusters.
☀️ Sunlight & Heat:
Generally stable in indirect light, but avoid excessive heat which may damage crystal structure.
🧼 Cleaning:
Avoid water immersion. Clean gently with a soft, dry brush or compressed air.
📦 Storage & Display:
Display in a protected location away from vibration or frequent handling. Apophyllite displays beautifully under soft, indirect lighting.
