Grandidierite was first discovered in 1902 in Madagascar by Alfred Lacroix, a French mineralogist. Lacroix named the mineral in honor of French explorer and naturalist Alfred Grandidier (1836–1912), the first authority on the natural history of Madagascar.
Since its initial discovery, samples of Grandidierite have been found in only a few locations around the world, including Malawi, Namibia and Sri Lanka. But the few gem quality specimens have come mainly from Madagascar.
Gem-quality Grandidierite is extremely rare, and it often appears on the list of the 10 rarest varieties in the world, along with gems like jeremejevite, painite, benitoite and taafeite.
Gemologically, Grandidierite is a magnesium aluminum borosilicate. It has a hardness of 7 to 7.5 on the Mohs scale, similar to garnet; a density of 2.85 to 3.00, in the approximate range of tourmaline; and a refractive index of 1.590-1.623.

Zašto korisnici nadmašuju same sebe?
Kada se postavi ponuda, to je najveći iznos koji je osoba spremna ponuditi za proizvod. Naš sustav će zatim automatski licitirati u ime ponuditelja, postupno povećavajući ponudu do maksimuma kako bi zadržao svoju poziciju ponuditelja najviše ponude.
Kada postoji ikona koja označava 'Automatsku ponudu', to znači da naš sustav aktivno daje ponude za ponuditelja na temelju njihove maksimalne ponude. Ovo se može činiti kao da ponuditelji sami sebe nadmašuju, ali to je jednostavno rezultat ažuriranja ponude sustava kako bi odražavala maksimalno ograničenje ponuditelja.
