DESCRIPTION
Grandidierite is a rare mineral that was first discovered in 1902 in southern Madagascar. The mineral was named in honor of French explorer Alfred Grandidier (1836–1912) who studied the natural history of Madagascar
Grandidierites appear bluer in color the more iron (Fe) they contain. A recently discovered gemstone, blue ominelite is the Fe-analogue (Fe, Mg) to grandidierite (Mg, Fe).[4]
Grandidierites display strong trichroic pleochroism. That means they can show three different colors depending on the viewing angle: dark blue-green, colorless (sometimes a very light yellow), or dark green.
While trichroism can usually help distinguish grandidierites from other gems, lazulites can occur with blue-green colors and show colorless/blue/dark blue pleochroism. Nevertheless, lazulites have somewhat higher refractive indices and specific gravity. Grandidierites also have greater hardness.

Pourquoi les utilisateurs se surenchérissent-ils ?
Lorsqu'une enchère est placée, il s'agit du montant maximum qu'un utilisateur est prêt à enchérir pour le produit. Notre système enchérira ensuite automatiquement au nom de cet utilisateur, augmentant progressivement l'enchère pour maintenir sa position d'enchérisseur le plus élevé, jusqu'au maximum spécifié.
Lorsqu'il y a une icône indiquant "Enchère automatique", cela signifie que notre système place activement des enchères pour l'utilisateur en fonction de son enchère maximale. Cela peut donner l'impression que les utilisateurs surenchérissent eux-mêmes, mais c'est simplement le résultat de la mise à jour de l'enchère par le système pour refléter la limite maximale des utilisateurs.
