Musgravite Rough Specimen — Certified

Among the rarest gemstones on Earth, musgravite was first described in 1967 from South Australia's Musgrave Ranges and for decades existed only in museum collections. By 2005, fewer than ten faceted examples were known worldwide. A small number of gem-quality crystals have since been found in Greenland, Madagascar, and Tanzania, but musgravite remains one of those gemstones that most jewellers will never handle in a career.

A member of the taaffeite family (another extreme rarity), musgravite displays a soft grey-green to violet colour that deepens with stone quality. Owning a piece of certified musgravite is, by any definition, an extraordinary act of collecting — a stone rarer than any diamond.
