Very esthetic specimen of celestine from Morocco. It shows us a large group of prismatic crystals of this strontium sulphate, very well defined and faceted, and with an excellent transparence that allows us to see a soft bluish color. They are disposed on a compact matrix. This locality is northeast of Imilchil town.
