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.

為什麼用戶出價高於自己？
出價時，這是一個人願意為產品出價的最高金額。然後，我們的系統將自動代表投標人出價，逐步將出價提高到最高價，以保持其最高出價者的地位。
當出現「自動出價」圖示時，表示我們的系統正在根據投標者的最高出價主動為其出價。這可能看起來好像出價者出價高於自己，但這只是系統更新出價以反映出價者最高限額的結果。
