Celestite, also called celestine, is strontium sulfate that grows as pale blue, glassy crystals, often lining the inside of geodes. It's soft and fragile, so it's sold mostly raw, as clusters, geode pieces and single crystals.

Before You Buy Celestite

How blue is it?

Usually pale sky blue, sometimes nearly colorless, white or gray. The glassy crystals often line the inside of a geode, so it's mostly sold as geode pieces and clusters.

Celestite or angelite?

Different minerals that can look alike. Angelite is a trade name for pale blue anhydrite, a calcium sulfate usually sold tumbled or polished. Celestite is strontium sulfate and feels noticeably heavier for its size.

Will the blue fade?

It can. Celestite's blue may fade with long exposure to strong light, and high heat bleaches it. Keep display pieces out of a sunny window.

Care

At 3 to 3.5 on the Mohs scale, its crystals scratch and chip easily. Lift a cluster by its base and dust it with a soft brush; mild soap and warm water are fine when needed.
