The face of this specimen is coated in many sparkly volborthite crystals. The platy, yellow-green, crystals of volborthite come from the Monument #1 Mine in Navajo County, Arizona, a uranium-vanadium (U-V) occurrence. The mine operated intermittently from 1942 to 1950 and briefly reopened in 1954. This mine is known for producing quality volborthite specimens, an uncommon secondary mineral composed of hydrated copper vanadate. The matrix also contains chrysocolla, adding contrast and further interest to this rare mineral specimen.
