T o date, a variety of interesting mineral inclusions have been reported in the emeralds from the deposits at Milzu-Kafubu, in Zambia (Sinlzanlzas, 1981). These include the micas biotite and phlogopite, rutile, and apatite. Recently, the author had the opportunity to study three rough emeralds and one faceted stone from this locality with inclusions that appeared to be tourmaline, a mineral that' has been reported as inclusions in emeralds from the Urals in the Soviet Union and from the Habachtal mine in Austria (Sinlzanlzas, 1981; Gubelin, 1974) but has not previously been noted as occurring in Zambian emeralds. If the inclusions the author observed are in fact tourmaline, then a new paragenetic relationship could be established and a new species added to the list of known inclusions in Zambian emeralds. To this end, the geology of the area is reviewed and the inclusions themselves described in detail. Also, the gemological properties of these
