description:
Fine example for the species, the specimen a compact grouping of lustrous banded rockbridgeite. In good condition.

Located in Waidhaus within the Upper Palatinate region of Bavaria, Germany, the Hagendorf South Pegmatite is a world-famous zoned granitic pegmatite deposit that was extensively mined for feldspar and lithium over many decades starting in the late nineteenth century. Formed through complex magmatic and hydrothermal processes, this historic mining site is internationally renowned among mineral collectors and scientists for its extraordinary diversity of phosphate minerals, boasting numerous type species. Among these is rockbridgeite, a striking dark green to dark brown secondary mineral that forms as a result of the low-temperature aqueous alteration and oxidation of primary iron-bearing phosphates within the pegmatite's weathered zones.
