Sphene, also known as titanite, is a rare calcium titanium silicate mineral. It is prized as a gemstone due to its striking brilliance and fire, which often rivals that of diamond. Its name derives from the Greek word “sphenos,” meaning “wedge,” referring to its typical crystal shape.
Key Characteristics:
1. Color: Sphene occurs in a variety of colors, including green, yellow, brown, orange, and reddish hues. The green variety is often the most sought after in jewelry.
2. Luster: It has an adamantine to resinous luster.
3. Fire: Sphene exhibits high dispersion, splitting light into a rainbow of colors, making it highly sparkly under proper lighting.
4. Hardness: It has a Mohs hardness of 5-5.5, making it relatively soft and suitable for occasional wear in jewelry.
5. Clarity: Sphene stones often contain inclusions, but clean specimens are more valuable.
6. Crystal Structure: It crystallizes in the monoclinic system, forming wedge-shaped crystals.

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。
