A collectors’gemstone is the group of naturally occurred minerals that are rarely found in gem quality.
Musgravite [(Mg,Fe,Zn)2BeAl6O12]or Magnesio taaffeite is among the rare and sought-after gems by collectors.
Faceted musgravites have been firstly foundin Sri Lanka and were reported by Demartin et al. (1993).
Musgravite is also known from some other localities,such as Musgrave Ranges Australia, France, Greenland, Madagascar, Antarctica (Schmetzer et al., 2005), Tunduru, Tanzania (Schmetzer et al., 2007) and from Myanmar (Renfro, 2013; Leelawatanasuk et al., 2014). Recently, the GIT-Gem Testing Laboratory (GIT-GTL) had a chance to identify two exceptional-quality musgravite never before tested by our lab.
