1.7" Vibrant Blue Azurite Crystals - Milpillas Mine, Mexico

This is a gorgeous cluster of lustrous, pristine, deep-blue azurite crystals collected from the Milpillas Mine in Sonora, Mexico. Small amounts of fibrous malachite crystals can be found peppered across the azurite. It has been mounted to an acrylic display base for a clean look.

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.
