Group of Rutile crystals, one of them of good size, on a limonite matrix that resembles a conglomerate. The Rutile crystals display a perfect example of the classic cyclic twin, with very bright, striated faces and a deep red color, visible in transparency and reflections under intense light. Although the first locality given on the market was the D.R. of Congo, the correct locality is Zambia, close to the D.R. of Congo border.
Kinyanfumbe is located in Mwinilunga District, Northwestern Province, Zambia, within the northern extension of the Central African Copperbelt. The area is underlain by Proterozoic metamorphic rocks of the Lufubu Group and volcano-sedimentary sequences of the Lufilian Belt, affected by Pan-African tectono-metamorphic processes. Local mineralization, of hydrothermal and metasomatic character, includes Quartz, Feldspar, and Be–Nb-bearing minerals formed in pegmatites and veins related to late-tectonic granitic intrusions.
