"FOOLS GOLD"
Weight 50.37 cts app
Size 25 x 23 x 14 mm approx
Chalcopyrite (or copper pyrite), looks like, and is easily confused with Pyrite, Chalcopyrite is one of the minerals refered to as "Fool's Gold" because of its bright golden color. But real gold is a more buttery yellow and is ductile and malleable.
As an ore od copper, the yield of chalcopyrite is rather low in terms of atoms per molecule. It is only 25%, compared to other copper minerals such as chalcocite, cuprite,covellite,or bornite However the large quantities and widespread distribution of chalcopyrite make it the leading source of copper. Chalcopyrite is a common mineral and is found in almost all sulfide deposits. Fine crystals of chalcopyrite have a unique character and can add to anyone's collection.
Chalcopyrite is a copper iron sulfide mineral that crystallizes in the tetragonal system. Currently, the most common source of copper ore is the mineral chalcopyrite, which accounts for about 50% of copper production
It has a brassy to golden yellow color and a hardness of 3.5 to 4 on the Mohs scale. Its streak is diagnostic as green tinged black.

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.
