Silver is a white metal that is the most highly reflective metal. Silver fine jewelry is usually fashioned into sterling silver, an alloy of silver that is 92.5 percent silver and 7.5 percent copper. Sterling silver is more durable than pure silver. Silver is less expensive than platinum and gold, but it tarnishes over time and requires regular cleaning. It has to be cleaned more frequently than the other metals. Sterling silver is sometimes plated with yellow or rose gold to give the look of a yellow or rose gold piece. This plating fades, especially with daily wear.
