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.

Zašto korisnici nadmašuju same sebe?
Kada se postavi ponuda, to je najveći iznos koji je osoba spremna ponuditi za proizvod. Naš sustav će zatim automatski licitirati u ime ponuditelja, postupno povećavajući ponudu do maksimuma kako bi zadržao svoju poziciju ponuditelja najviše ponude.
Kada postoji ikona koja označava 'Automatsku ponudu', to znači da naš sustav aktivno daje ponude za ponuditelja na temelju njihove maksimalne ponude. Ovo se može činiti kao da ponuditelji sami sebe nadmašuju, ali to je jednostavno rezultat ažuriranja ponude sustava kako bi odražavala maksimalno ograničenje ponuditelja.
