Topaz

specimen number:
2354009

location:
Karengerenge, Kalumbila, Zambia

description:
Very choice lustrous gemmy Imperial topaz crystal. Sharply formed and in great condition.

Located in the North-Western Province of Zambia near Kalumbila, Karengerenge is situated within the mineral-rich Lufilian Arc region, where Neoproterozoic Katangan metasedimentary rocks hosted extensive regional metamorphism. Geologically, the surrounding basement host rocks feature rich pegmatitic and quartz-veined structures that favor high-grade mineralization. Historically, while the broader Kalumbila region became prominent for large-scale modern commercial open-pit copper mining, localized artisanal mining and collecting around Karengerenge gained distinct popularity among mineral collectors for producing fine gem-grade topaz crystals, including sought-after pink, imperial, and sherry-colored varieties.
