What is Celestite?
Celestite, also called celestine, is a strontium sulphate mineral often collected as delicate pale-blue crystal clusters. Typical material appears in pale sky blue, white or colourless shades, and is commonly described as strontium sulphate mineral. The Mohs hardness for this material is approximately 3–3.5; hardness refers to resistance to scratching, not to breaking, cleavage or sensitivity to chemicals. Most examples are better suited to mineral display than regular jewellery because crystals are soft and fragile. Typical geological or commercial source regions include Madagascar; Tunisia; this does not establish the provenance of an individual gem. Dust with a very soft dry brush; avoid soaking fragile clusters and direct impact. Ask for confirmation of identity, natural or lab-created status, and any treatments when choosing an individual stone.
