Description
Azurite, similar to the more expensive lapis lazuli, is a naturally occurring blue copper crystalline mineral originally found in the Sinai desert. It is a pale, slightly greenish sky blue used as a pigment since ancient times and found in Eighteenth Dynasty (1543–1292 BCE) Egyptian wall paintings. Also known as mountain blue or as Azurro Della Magna, it is a major source of the blues used by medieval painters in Europe as deposits were subsequently identified in France and Saxony.
