Grandidierite is an extremely rare mineral and gem that was first discovered in 1902 in southern Madagascar. Named by A. Lacroix in 1902 in honor of Alfred Grandidier (20 December 1836, Paris, France - 13 September 1912, Paris, France), French explorer and naturalist. He visited Madagascar three times between 1865-1870, crossing the island three times. With others, he wrote L'Histoire physique, naturelle et politique de Madagascar, a work spanning 40 volumes.
