Platinum's density and resistance to wear, make it the most secure, protective metal for settings and protecting your diamond. Radiant and resistant, platinum is one of the most durable of the precious metals used in jewelry due to its density and unique metallurgic properties. It is, however, softer than gold and will scratch more easily. But its purity gives off a cool white sheen that makes it an ideal combination with diamonds. Routine cleaning will help to maintain its unique appearance. Platinum jewelry should be soaked in a mild solution of soap and warm water. Gentle scrubbing with a soft-bristled brush is also recommended to help protect its luster and shine. Over time platinum develops a natural patina. If you want to maintain a glossy look, get your platinum jewelry cleaned and polished professionally every few years. Storing your platinum jewelry items in a fabric-lined box also helps to prevent scratches.
