Welcome to SuchenGems!
Bastnasite is a rare, hexagonal gemstone known for its warm colors, typically ranging from wax-yellow to reddish-brown, and its vitreous to greasy/pearly luster. It is a source of rare-earth elements and is difficult to cut due to its softness and brittleness, but its high refractive index makes it an interesting gem for collectors.

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.
