Unique and Striking Azurite Malachite Stud Earrings.
These colorful stones are set in heavyweight Sterling Silver prongs, Truly heirloom pieces that will last a lifetime.
The stones measure approximately 10mm across.
The bright blue and green copper carbonate minerals azurite and malachite are known as secondary minerals, because in the geological sequence that leads to lovely specimens like the one in the photo they form from pre existing elements and minerals, replacing them with something more appropriate for the environmental conditions. In the case of these beauties the journey likely started with hot copper rich fluid being expelled from a crystallising granite somewhere in the depths of the Earth. Conditions were anoxic and the copper was carried in a loose bond with an element such as sulphur or chlorine, until the fluid encountered a change in chemical or pressure/temperature conditions that forced some elements out of solution.
