It’s elemental. Like gold and silver, platinum is a pure natural element found on the periodic table. Dense, ductile and malleable, it’s considered one of the noble elements because of its non-reactive nature. It doesn’t corrode. It doesn’t tarnish. Its enduring nature makes it perfect for jewelry. Over time, platinum pieces develop a patina, a soft sheen born of fine scratches from wear. Although desirable, the patina may be removed by a simple soft polishing restoring the original smooth surface.
