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.

Zašto korisnici nadmašuju same sebe?
Kada se postavi ponuda, to je najveći iznos koji je osoba spremna ponuditi za proizvod. Naš sustav će zatim automatski licitirati u ime ponuditelja, postupno povećavajući ponudu do maksimuma kako bi zadržao svoju poziciju ponuditelja najviše ponude.
Kada postoji ikona koja označava 'Automatsku ponudu', to znači da naš sustav aktivno daje ponude za ponuditelja na temelju njihove maksimalne ponude. Ovo se može činiti kao da ponuditelji sami sebe nadmašuju, ali to je jednostavno rezultat ažuriranja ponude sustava kako bi odražavala maksimalno ograničenje ponuditelja.
