Afghanite, (Na,K)22Ca10[Si24Al24O96](SO4)6Cl6,[1] is a hydrous sodium, calcium, potassium, sulfate, chloride, carbonate alumino-silicate mineral. Afghanite is a feldspathoid of the cancrinite group and typically occurs with sodalite group minerals. It forms blue to colorless, typically massive crystals in the trigonal crystal system. The lowering of the symmetry from typical (for cancrinite group) hexagonal one is due to ordering of Si and Al.[1] It has a Mohs hardness of 5.5 to 6 and a specific gravity of 2.55 to 2.65. It has refractive index values of nω=1.523 and nε=1.529. It has one direction of perfect cleavage and exhibits conchoidal fracture.[3] It fluoresces a bright orange.

Argemsjewelry shipped item to wrong address and zip code, I did not receive item, then have to go through a long refund process. I would save myself time and not buy from this seller again.

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。
