1.5" Vivid Blue, Cut/Polished Azurite Nodule - Siberia
This is an incredibly vivid-blue azurite nodule that has been cut in half and polished. One half of the nodule is included. These vibrant nodules/geodes come from Rubtsovsk mine in Altai Krai, Siberia.
Azurite is a copper carbonate hydroxide mineral best known for its beautiful and vibrant blue appearance. Azurite typically forms in nodular formations with other colorful, copper-rich minerals. It is a secondary mineral that precipitated in pores, crevices, and caverns from water with high concentrations of carbon dioxide.
Azurite and malachite are known to form in union with each other since their chemical makeup is very similar. In fact, the presence of more or less water in the location of formation is enough to determine whether an abundance of malachite over azurite, or vise-versa, will accumulate.
