Musgravite

Musgravite
Musgravite 5.03 cts, Ratanapura, Sri Lanka

Very rare collector gemstone Musgravite cushion weighing 5.030cts from the Ratanapura, Sri Lanka.  Musgravite is an extremely rare member of the taaffeite family that was discovered in 1967 in the Musgrave Range of South Australia. Facet grade musgravite was not reported reported until 1993 and as of 2005, there were only eight musgravite specimens, three of which were identified by Murray Burford, a Canadian gemologist. The mineral was has since turned up in Greenland, Madagascar, Antarctica, Sri Lanka, and Tanzania.  Because of its similarity to taaffeite it is probable that some stones originally thought by their owners to be taaffeites, are actually musgravites. The largest known musgravite is owned by Multicolour.com and weighs a 5.74cts
