Aquamarine is a pale-blue to light-green variety of beryl.[2] Greenish-blue aquamarine can be changed to pure-blue by heat.[3]
The aquamarine has a chemical composition of Be3Al2Si6O18,[4] also containing Fe2+.[5] It has a hardness of 7.5 to 8.[6] Aquamarine contains no or little noticeable inclusions.[7] But it can have inclusions like mica, hematite, or salt-water.[8]
Aquamarine is a common gemstone.[9] However there is a rarer variant of aquamarine called maxixe which is deep blue in color,[7] but its color can fade due to sunlight.[1] The color of maxixe is caused by NO3.[10] Dark-blue maxixe color can be produced in green, pink or yellow beryl by irradiating it with high-energy particles (gamma rays, neutrons or even X-rays).[11]

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。
