Azurite crystals. The specimen at top right is polished, the specimen at bottom is in its natural state. Azurite is a hydrated copper carbonate mineral. Its name refers to its colour, azure. In medieval times, the mineral was ground up and used by painters as a blue pigment. Azurite's colour also makes it popular with mineral collectors.
