Summary
[edit]DescriptionAzurite malachite cabochon gemstone.JPG |
English: Azurite and malachite are both crystals formed by the weathering process that breaks down natural copper ore deposits. Azurite is a brilliant blue with a hardness of around 3.5 to 4 on the Mohs scale as well as a specific gravity of around 3.77 to 3.89 and a refractive index of 1.655-1.909. Azurite is mined for use in paint pigments, often producing a range of blues dependent on the mineral’s natural color.
Malachite is the Greek translation of moloche, meaning mallow, due to its color. Read more about azurite / malachite at: http://ezinearticles.com/?Azurite-and-Malachite---The-Travellers-Guardian-and-Peacock-Gemstones&id=2457723 |
