Celestite
Celestite, a strontium sulphate mineral with formula SrSO₄.
Also known as: celestite · selestit
Celestite is a strontium sulphate mineral with formula SrSO₄. It pale blue crystal clusters are prized by collectors; fragility limits jewellery use.
Its physical identity is distinct from spiritual interpretation. It is associated with silence, contemplation and a sense of spaciousness. These correspondences are symbolic uses in modern crystal culture, not measured mineral effects.
Because of its low hardness it should be protected from scratches and impact and cleaned gently with a dry, soft cloth. Spiritual interpretations belong to belief and personal experience; they do not replace medical diagnosis or treatment. Mineral dust must not be inhaled during cutting or grinding.
