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.

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。
