3.15CT Natural katlang Topaz cushion Cut Stone
Weight:(3.15)CT
Stone:(Topaz)
Origin:(Pakistan from Katlang)
Topaz is a silicate mineral made of aluminum and fluorine with the chemical formula Al2SiO4(F, OH)2. It is used as a gemstone in jewelry and other adornments. Common topaz in its natural state is colorless, though trace element impurities can make it pale blue or golden brown to yellow-orange.[7] Topaz is often treated with heat or radiation to make it a deep blue, reddish-orange, pale green, pink, or purple.[8]
Topaz is a nesosilicate mineral, and more specifically, an aluminosilicate mineral.[9] It is one of the hardest naturally occurring minerals and has a relatively low index of refraction. It has the orthorhombic crystal system and a dipyramidial crystal class.[10]
It occurs in many places in the world. Some of the most popular places where topaz is sourced are Brazil and Russia.[7] Topaz is often mined in open pit or alluvial settings.[11]

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