Azurite mineral specimens with malachite from Namibia, azurite is an eye catching rich blue mineral specimen and a major copper ore. This mineral has been known to humans for centuries and aside from being a copper deposit indicator was also historically used as a blue pigment for early paint and in jewellery. It is a carbonate mineral which is unstable at the surface, more so than malachite, as such, it has a tendency to pseudomorphically be replaced by malachite, which is why the two are so often found together, creating vibrant contrasts of green and blue. These particular mineral specimens come from the Tsumeb Mine (5.1 sublevel, west 4 stope), Tsumeb Oshikoto region, Namibia and is rare to obtain. Supplied in lots of 250 grams in a polythene bag with an information label. The size of the pieces ranges from approximately 5 mm to 2 cm.
