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.

Perché gli utenti superano se stessi?
Quando viene fatta un'offerta, questo è l'importo massimo che una persona è disposta a offrire per il prodotto. Il nostro sistema farà quindi automaticamente un'offerta per conto dell'offerente, aumentando gradualmente l'offerta fino al massimo per mantenere la sua posizione di miglior offerente.
Quando c'è un'icona che indica "Offerta automatica", significa che il nostro sistema sta attivamente piazzando offerte per l'offerente in base alla sua offerta massima. Questo potrebbe sembrare come se gli offerenti stessero superando se stessi, ma è semplicemente il risultato del sistema che aggiorna l'offerta per riflettere il limite massimo degli offerenti.
