An exceptional and highly sought-after specimen of Afghanite from the legendary Sar-e-Sang locale in Badakhshan, Afghanistan. It showcases a rich, deep blue color with striking zoning and is accentuated by small, scattered Pyrite crystals. The piece exhibits extremely strong UV-reactivity, a hallmark of the finest Afghanite, transforming under short-wave ultraviolet light. This remarkable fluorescence, combined with its defined crystal structure and aesthetic Pyrite association, makes this a particularly desirable specimen for advanced collectors of fluorescent minerals or rare feldspathoids.
