Rare crystal of Grandidierite. When you can find any, Grandidierite specimens are almost always just massive pieces. Though non-terminated or crudely terminated,
this is a complete crystal all around. Grandidierite is a rare magnesium aluminum borosilicate first discovered in 1902
in the Anosy Region of Madagascar and often appears on lists of the 10 rarest gems in the world. Highly translucent with great blue green color.
Weighs 1.2 grams.
