Platinum

 Platinum is the rarest and sturdiest of all jewelry metals. The purity of this metal makes it naturally hypo allergenic which is good for people with sensitive skin. As a result of the density of this metal makes it the most secure metal for setting gems in. It also has a naturally white color therefore it will not need plating or fade. Over time there will be natural wear and tear such as patina or minor scratches. The best way to clean platinum is warm soapy water and a soft brush.
