Precious metals have always been a detector of prosperity and high social rank. Just remember that jewelry was always a very inaccessible good for ordinary people. Only kings and emperors, priests and pirates could own the jewelry. Ancients believed that precious stones have always had some magical power that is why jewelry was so rare and prohibitive. There are two types of jewelry – stones and metals. Obviously both of them are unique because of their appearance. It seems that our fanatic desire to have jewelry is the result of some psychological peculiarities. Probably we have inherited this weakness. But you know that jewelry gives a feeling of freedom and identity.
