This specimen features calciovolborthite, now officially known as tangeite, from the Monument 1 Mine in Navajo County, Arizona. Tangeite is a rare calcium copper vanadate, typically found as a secondary mineral in the oxidized zones of vanadium-bearing hydrothermal deposits. This mineral is even more intriguing when observed under microscope or loupe. The Monument 1 Mine is known for producing high-quality specimens of this rare mineral. Tangeite forms through the alteration of primary vanadium minerals in the presence of copper and calcium, giving rise to the eye-catching green hues. Specimens like this one offer an excellent opportunity to study the mineral's crystallography and colour.
