📜 Key facts

AgeVaries by deposit
Origin & sourcesMorocco, Mexico, England and the USA. It is often sold as 'selenite' wands and towers.
CompositionFibrous gypsum (CaSO₄·2H₂O). Most 'satin spar' sold today is gypsum, not calcite, although the name was once also used for fibrous calcite and aragonite

How it forms

Gypsum grew in parallel fibres in veins, giving a silky sheen. It is soft (Mohs 2) and slightly water-soluble, so keep it dry.
