Rhodonite is an attractive mineral that is often carved and used in jewelry. It is named after the Greek word for rose, rhodon. Its rose-pink color is distinctive and can only be confused with rhodochrosite and the rare mineral, pyroxmangite, MnSiO3. Rhodochrosite however is streaked with white minerals such as calcite and is reactive to acids. While rhodonite does not react to acids and is usually associated with black manganese minerals and pyrite. Pyroxmangite is a little harder to distinguish because the two minerals are closely related and x-ray studies are usually needed when found massive. Crystals of pyroxmangite are often twinned as is not the case with rhodochrosite crystals. Crystals of rhodonite, while not in nearly the same abundance as massive rhodonite, are still found and distributed on the mineral markets. They come from a few notable localities and are considered classics by collectors.

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.

Revizija

Program Gemstone Sheriff omogućuje našim članovima da zatraže reviziju bilo kojeg proizvoda, koju dovršava neovisna Gemologist koja procjenjuje točnost opisa artikla i slika.
