Aquamarine with Phenakite

Here we have an absolutely fantastic saturated gemmy aquamarine from Mt. Antero Colorado. The piece has great luster and is heavily etched. There is a small 0.4cm euhedral phenakite attached to the side of the specimen. The bottom of the crystal is contacted. Mt. Antero may be the highest elevation mineral-collecting locality in the contiguous 48 states, at over 13,000 feet (over 3,962m). It is generally accessible only in late summer and then is difficult due to summer storms and low oxygen levels in the air. It is located within the San Isabel National Forest, about 15 miles northwest of Salida, in a chain of 14,000-foot (4,267m) peaks in the Collegiate Range. Mineral specimens have been collected at Mt. Antero from pegmatites and miarolitic cavities in granite since 1885. (Jacobson, 1979). A true USA classic!
