Other/historical names associated with this locality:
Mdarara
Large ruby crystals in green (Cr-bearing) zoisite matrix ('anyolite'), well-known on the mineral market.
The mine is named after a nearby Maasai village (Mdarara).
Located ca. 27 km W of Longido, and about 100 km NW of Mt Kilimanjaro.
See also the mineralogically similar locality http://www.mindat.org/loc-211915.html.
Note on the mineral list: The amphibole embedded in the green zoisite has been identified as pargasite rather than "aluminotschermakite" (a synonym of tschermakite) or tschermakite, see http://www.mindat.org/mesg-7-279523.html.
