About the stone

What is Heulandite?

Heulandite is a zeolite that grows as flat, coffin-shaped crystals with a pearly face, in white, peach, red or green.

Maharashtra's basalt quarries produce colourful heulandite, often with stilbite and apophyllite.

Care & cleaning

A softer stone — wipe with a soft, slightly damp cloth, avoid harsh chemicals and knocks, and store separately from harder crystals.
