The Madagascar’s Paraiba

Image module

Grandidierite is one of the rarest gems in the world. This blue-green silicate can recall Tourmaline paraiba and is just as fascinating.

Discovered at the beginning of the 20th century by Alfred Lacroix, the deposits are mainly found in Madagascar. It was named in honor of the French explorer and naturalist Alfred Grandidier (1836-1921) who studied the natural history of the island.

Some stones have been found in Algeria and New Zealand, however their small size does not allow faceting.
Grandidierite is one of the ten most rare gems in the world.

Very included and generally small, pure stones of more than one carat exceed the price of diamonds.

The hardness of 7.5 on the Mohs scale, the cut grandidierite can be set on a necklace, earrings or a ring.
