A brilliantly transparent gem, sphene has fire greater than that of diamond! This gem is named from the Greek word for “wedge,” as its crystals are typically wedge shaped, but may be referred to by its mineral name, titanite. Another characteristic sphene possesses is birefringence, or double refraction, meaning that light splits into two rays as it passes through the gem. As a result, the back facets appear as double images, giving the gem a soft, hazy appearance, similar to the doubling seen in zircon.

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。
