Platinum is, in a way, the best metal for jewelry rather than silver or gold, which does not stain like silver.

Since several jewelers began to use the metal in the late 1800s, platinum quickly grew in popularity, becoming particularly fashionable for the establishment of colorless stones, which lasted until 1940, when platinum use was restricted to industrial production of chemicals needed to strengthen the war. Platinum has been replaced by white gold because of these restrictions, but has returned to be popular in recent years.

Platinum alloys are used in a wide range of configurations where chemical inertia or wear resistance are important, including medical devices, laboratory instruments, electrical contacts, spark plugs and turbine engines.
