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.

なぜユーザーは自分自身を上回る入札をするのでしょうか?
入札が行われる場合、これはその商品に対して入札者が入札する最高額となります。その後、当社のシステムは入札者に代わって自動的に入札し、最高額まで入札額を段階的に引き上げていき、最高入札者としての地位を維持します。
「自動入札」を示すアイコンがある場合、当社のシステムが入札者の最高入札額に基づいて入札者に代わって入札を行っていることを意味します。入札者が自らの入札額を上回る入札をしているように見えるかもしれませんが、これは入札者の最高額を反映するようにシステムが入札額を更新した結果にすぎません。
