{"product_id":"azurite-on-malachite-13","title":"AZURITE on MALACHITE","description":"Not only is this a wonderfully 'contrasty' colourful miniature of Malachite and Azurite from the famous Copper Queen mine at Bisbee, Cochise Co., Arizona, but its textures are intriguing too. The Malachite, if indeed that is what it still is, shows the classic concentric growth banding and mid-green colour which one might expect for Malachite but it possesses an unusually soft, smooth, porous talc-like texture, suggesting that maybe it has altered to Chrysocolla, or perhaps Chalcoalumite, but with some of the colour of Malachite remaining. Presenting as a cross-section through the layers of copper mineralization, the concentric bands of botryoidal Malachite are then encrusted by a 4 to 5 mm thick layer of deep blue bladed Azurite crystals, aggregated in compact clustered rosetted forms on the outer surface where its colour is so dark blue as to look almost black. A really fascinating and intriguing Bisbee specimen.
