Where in the world?

According to Forbes, grandidierite the 3rd most rare gemstone in the world. First discovered in 1902 by the French mineralogist Alfred Lacroix in the southern region of Madagascar. .

Lacroix paid homage to the renowned French explorer and naturalist Alfred Grandidier by naming this glorious gemstone after him – the first authority on the natural history of Madagascar.

Exquisite colour, hardness and location make jewellery quality grandidierite hard to come by. Since its initial discovery in 1902 it has only been found in a few countries around the world, those being Malawi, Namibia and Sri Lanka. But the few gem quality samples have come largely from Madagascar.
