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.

Name: GRANDIDIERITE GEMSTONE

Why are users outbidding themselves?

When a bid is placed, this is the maximum amount a user is willing to bid for the product. Our system will then automatically bid on that users behalf, incrementally increasing the bid to maintain their position as the highest bidder, up to the specified maximum.

When there is an icon indicating 'Auto Bid,' it means our system is actively placing bids for the user based on their maximum bid. This may appear as if users are outbidding themselves, but it's simply a result of the system updating the bid to reflect the users maximum limit.

Audit

The Gemstone Sheriff program allows our members to request an audit on any product, which is completed by an independent Gemologist who assesses the accuracy of the item description and pictures.
