Thier polish and luster were still perfect, giving dramatic proof of platinum's incomparable strength and durability. Another ancient people who created adornments from platinum were the Incas. They even went so far as to throw great amounts of the metal into the sea, thinking that it might become a cheap imitation for silver. Finally, during the eighteenth century, platinum's value as a metal supremely suited for jewelry started to take hold. Then in the nineteenth century, platinum became the de-facto standard for setting the finest of the newly discovered gemstone, the diamond.
Platinum is the hardest of the precious metals, it never tarnishes.
Its intense luster remains intact over the years, and it is completely hypoallergenic. Platinum is extremely dense, and remarkably heavy. Much more so than silver or gold. This property of platinum enhances and ennobles the quality of the jewelry from which it is created. The ultimate stability of platinum over the years is unmatched.
