Rare Grandidierite 0.21ct Exceptional Gem Quality Madagascan Grandidierite 4.5x3mm

Grandidierite was first described in southern Madagascar in 1902. The mineral is very rare; gem-quality material of facetable size was almost unheard of in the market before the summer of 2015. The pieces I have for sale are from my collection, purchased in 2015 alongside the GIAs verification of the material find in Madagascar.
