Platinum is a silver-white metal that is even more valuable than gold. It will not corrode or tarnish as many metals do when exposed to air. It can be used as a catalyst in processes that change harmful pollutants into nonpollutants. Platinum is also a favorite with jewelers. Its resilience and hardness make it ideal for gem settings. Most platinum is produced in Russia, Japan, South Africa, and Colombia.
