Old Yuma Mine (Yuma Mine), Saguaro National Monument, Amole District, Tucson Mts, Pima Co., Arizona, USA
Miniature, 4.0 x 3.6 x 2.6 cm
Old Yuma Mine vanadinites compare favorably with the best United States vanadinites, including the Apache and North Geronimo (Pure Potential) Mines. And Old Yuma vanadinites are less common. Lustrous, brick-red, hexagonal vanadinite barrels to 5 mm cover the matrix on this classic specimen. The vanadinites have a preferential coating on one face. This piece probably dates to the 1960s or 1970s. Ex. Jaime Bird Collection.
