Amethyst in the Goboboseb Mountains was first brought to light in the early 1950s, but concerted prospecting didn’t commence until roughly thirty years later, when collectors and small-scale miners began extracting pale to deep violet amethysts from basaltic geodes. Amethysts in the Goboboseb Mountains formed inside hollow, rounded cavities (geodes) in basalt around 100 million years ago. This region has yielded some of the finest amethyst ever found, coveted by collectors for the deep purple hue. This large (2kg+) specimen is in good condition and displays vibrant purple color when backlit.
