Translucent blue green Grandidierite as a rare single crystal, though not terminated. 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. Crystals are very rare and ususally the best you can hope for are some crystal
faces as they ususally grow in narrow seams. Translucent with great color.
