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.

なぜユーザーは自分自身を上回る入札をするのでしょうか?
入札が行われる場合、これはその商品に対して入札者が入札する最高額となります。その後、当社のシステムは入札者に代わって自動的に入札し、最高額まで入札額を段階的に引き上げていき、最高入札者としての地位を維持します。
「自動入札」を示すアイコンがある場合、当社のシステムが入札者の最高入札額に基づいて入札者に代わって入札を行っていることを意味します。入札者が自らの入札額を上回る入札をしているように見えるかもしれませんが、これは入札者の最高額を反映するようにシステムが入札額を更新した結果にすぎません。
