Information about Angelite

A commonly used trade name for Blue Anhydrite, which is a fairly uncommon mineral that is similar to Gypsum. Anhydrite actually changes to Gypsum in water, which is why this stone is relatively uncommon – this is reversible with a fairly small amount of heat in certain circumstances.

Due to its Calcium content, this stone can be ground up and used as a soil treatment, and is used in construction and building materials like plaster, along with Gypsum. Synthetic Anhydrite is actually a side product of the production of Hydrofluoric Acid, although this is far more likely to be used in construction materials than tumbled!

It is found in a range of places, especially in arid climates, where water has not turned the stone into Gypsum – Mexico produces some excellent specimens with a good blue colour.

It is a relatively soft stone, and is not often used for jewellery for that reason. It is usually found tumbled, or carved into decorative objects, or cabochons for wirewrapping.
