Angelite, the blue-white variation of Anhydrite, is a sulfate-based stone that can easily convert to gypsum depending on its natural habitat at the time of formation and deposit. Angelite is sometimes referred to as Blue Anhydrite. This name comes from the Greek word, anhydras, meaning “without water.” It is typically found in salt flat basins, tidal flat nodules, salt dome cap rocks, and within igneous rocks. It can be found in a number of places where the salt content is high and water concentration low. Most commonly it can occur with gypsum and other Calcite stones. 

Angelite was first discovered in Peru and came on the market in the late 1980s, making it a newer crystal. Angelite is a very precise formation and color of the anhydrite gems. Even though it is found worldwide, it is still considered a rare stone. The trade name of Angelite carries intentional connections to the word angelic and is linked with this connotation as it has "heavenly" blue colors and soothing characteristics.
