This citrine is from a locality near the village of Lwena on the Congolese-Zambian order, Lubumbashi, Katanga Province, Democrtic Republic of the Congo. Citrine is the only mineral noted for the location and it is found in the form of single crystals and complex clusters of crystals that are sometimes referred to as “Cathedrals”. Citrine is the name given to the yellow-orange variety of quartz. Quartz in pure form is colorless and different varieties (or colors) such as citrine, amethyst or rose are caused by trace impurities in the crystal lattice. Extraction of the citrine specimens from the Lwena deposit appears to be difficult as the specimens are rarely in pristine condition. Unlike most pieces which have some kind of bruising or dings this piece is damage free. The crystals are mostly transparent with internal veiling and they have a glass luster. This piece measures 2 x 1 3/4 x 1 1/2 inches or 50 x 45 x 38 mm.
