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.

为什么用户出价高于自己?
当有人出价时,这是某人愿意为产品出价的最高金额。然后我们的系统将自动代表竞标者出价,逐步提高出价直至最高价,以保持其最高出价者的地位。
当出现“自动出价”图标时,表示我们的系统正在根据出价者的最高出价为其出价。这可能看起来像是出价者在出价高于自己,但这只是系统更新出价以反映出价者的最高限额的结果。
