Abstract
Klein Spitzkoppe has been producing topaz crystals for over 100 years. Since the discovery of the pegmatite in 1889, many fine crystals have been collected and thousands of carats of gemstones have been faceted from colorless, transparent, so-called "silver topaz." Most topaz specimens consist of loose crystals, but some rare matrix pieces with microcline and smoky quartz are known. Associated collectable minerals including beryl (aquamarine), green fluorite, phenakite and bertrandite have also been found there.
