Taking care of platinum and gold is less tricky than taking care of silver. Platinum is a precious metal that has a shiny white finish. Platinum does not tarnish or corrode. It is by far the most wearable metal of all. With time, however, platinum changes its finish from shiny to matte. Simple polishing can buff the color back to its original shiny lustre.
Gold requires more attention than platinum but less than silver. Gold is quite a hard metal, yet its surface can scratch. Because of this, gold needs to be kept in a separate storage place away from hard gemstones like diamonds, as they can easily scratch your gold jewelry. Extra care is needed when handling white gold as the various alloyed metals in white gold make the color not as bright as platinum. Because of this, there is platinum plating on all white gold jewelry. With time, platinum plating wears out which makes white gold jewelry look dull. Rhodium plating is the process of recovering the white lustre of white gold jewelry and should be done periodically on white gold pieces.
