Watch a video of this specimen by following the Vimeo link below: https://vimeo.com/1011829183 Here is a splendid quality and architecture azurite specimen from the porphyry 'iron caps' of Arizona (possibly from Morenci mine)! It shows a stunning assemblage of azurite rosettes made up of extremely thin crystals which makes for a velvet-like visual effect, that displays an intense royal blue colour. Some halloysite-type clear clays are trapped here and there, which could maybe help identifying the accurate locality. Overall, the specimen is in excellent condition: this is really a superb American azurite and an international classic! Ex anonymous Parisian collection.
