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.

¿Por qué los usuarios se superan a sí mismos?
Cuando se realiza una oferta, este es el monto máximo que una persona está dispuesta a ofertar por el producto. Nuestro sistema ofertará automáticamente en nombre del postor y aumentará la oferta de manera gradual hasta el máximo para mantener su posición como el mejor postor.
Cuando hay un ícono que indica "Oferta automática", significa que nuestro sistema está realizando ofertas de forma activa para el postor en función de su oferta máxima. Esto puede parecer como si los postores estuvieran pujando más que ellos mismos, pero es simplemente el resultado de que el sistema actualiza la oferta para reflejar el límite máximo del postor.
