Metallic, and silver-white in color, one of the precious metals, although considerably less valuable than gold or platinum. Exposure to oxygen or the air causes a black oxidation to form on the surface (silver-oxide), also known as tarnish.

We offer gold, silver and platinum in our jewelry settings.
