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.

Waarom overbieden gebruikers zichzelf?
Wanneer een bod wordt geplaatst, is dit het maximale bedrag dat een persoon bereid is te bieden voor het product. Ons systeem zal dan automatisch bieden namens de bieder, waarbij het bod stapsgewijs wordt verhoogd tot het maximum om hun positie als hoogste bieder te behouden.
Wanneer er een pictogram is dat 'Automatisch bod' aangeeft, betekent dit dat ons systeem actief biedingen plaatst voor de bieder op basis van hun maximale bod. Dit kan lijken alsof bieders zichzelf overbieden, maar het is gewoon een resultaat van het systeem dat het bod bijwerkt om de maximale limiet van de bieder weer te geven.
