An extra quality Azurite Mineral Rough. Electric blue in colour on both sides and solid, this is an excellent collectors specimen. A blast of colour for the collection, quite hard to photograph it is so bright and dark blue. There is some Malachite is also visible on the back and interesting layering visible from the sides. A good, chunky piece of quality Azurite for the crystal or mineral collector. Azurite is a popular mineral due to its vibrant colour, a deep blue called “azure”, hence its name. Quite a heavy piece for its size, due of course to the Copper content.
7cm x 10.5cm x 2.1cm, 254g.
The colour is due to Copper which is a strong coloring agent. Copper chemically combines with the carbonate groups CO3 and hydroxyls OH. Azurite has been used as a dye for paints and fabrics for eons. Unfortunately its colour is too deep and larger crystals can appear black. Small crystals and crusts show the lighter azure colour well. Azurite is often associated with its colourful close cousin Malachite.
