Precious Metals Magic

Excerpt:

A precious metal is distinguished by its high economic value and its resistance to corrosion or oxidation. Their high luster or reflective shine and their high electrical conductivity make them more valuable than the metals used for other purposes, such as iron, lead, or tin. 

The noble metals gold, silver, platinum and palladium and are used as currency in coinage and/or in jewelry or art. Other precious metals include the platinum group metals: ruthenium, rhodium, palladium, osmium, iridium, and platinum, of which platinum is the most widely traded.
