Apophyllite

Apophyllite is apophyllite group. Glassy square or pyramidal crystals can look almost too perfect, which is part of their natural appeal. This page separates mineral facts from retail terminology and traditional crystal symbolism so you can compare pieces more confidently.

What Apophyllite is

Apophyllite commonly forms as secondary crystals in cavities of basaltic volcanic rocks, often with stilbite and other zeolites. Its listed Mohs hardness is 4.5–5, and its crystal system or structural category is Tetragonal / orthorhombic group members. The chemical composition is commonly written as Complex hydrated potassium-calcium silicate.

What to look for when buying

Perfect-looking clusters can still be natural, but inspect for glue around broken points and matrix joins. Treatments are not automatically a problem, but they should be disclosed. For apophyllite, common treatment or enhancement notes include: Usually untreated; repaired points and glued matrix pieces can occur.

Care and display

Water: Avoid soaking and sudden temperature changes; crystals have good cleavage. Light: Keep away from strong heat and prolonged harsh sun.

Traditional associations

A crystal should not be used as a substitute for medical, mental-health, financial or other professional advice.

Where it works visually

Common display ideas include shelf, bedroom. Placement should also account for hardness, cleavage, sunlight, humidity, pets, children and how easy the specimen is to knock over.
