AIG Certified 3.27CT high Quality Natural Cobalt Spinel from~Tanzania
Stone:(Cobalt Spinel)
Cobalt spinel usually refers to a gem-quality spinel mineral colored by cobalt. It is famous for its incredibly vivid electric blue hue—often considered one of the most striking blues in the gemstone world.
What It Is
Chemical family: Spinel (MgAl2O4)
Color agent: Trace amounts of cobalt substituting into the crystal lattice
Typical color: Intense, saturated, neon-like blue (sometimes called “cobalt blue spinel”)
Why It’s Special
The blue is exceptionally pure, vivid, and bright—often compared to high-quality sapphires.
Cobalt-bearing spinels are rare, especially in clean, well-saturated stones.
They fluoresce strongly under some types of light due to the cobalt content.

Pourquoi les utilisateurs se surenchérissent-ils ?
Lorsqu'une enchère est placée, il s'agit du montant maximum qu'une personne est prête à enchérir pour le produit. Notre système enchérira alors automatiquement au nom de l'enchérisseur, augmentant progressivement l'enchère jusqu'au maximum pour maintenir sa position de meilleur enchérisseur.
Lorsqu'une icône indiquant « Enchère automatique » apparaît, cela signifie que notre système place activement des enchères pour l'enchérisseur en fonction de son enchère maximale. Cela peut donner l'impression que les enchérisseurs se surenchérissent, mais c'est simplement le résultat de la mise à jour de l'enchère par le système pour refléter la limite maximale des enchérisseurs.
