Platinum is a naturally white metal so it will not cast any of its own color into a diamond. Usually 95% pure (by comparison 18 karat gold is 75% pure), platinum never fades or tarnishes but keeps its natural white color for a lifetime. As platinum is so pure, it is naturally hypoallergenic and ideal for those with sensitive skin.
Platinum’s unequalled durability and resistance to wear makes it the most secure and protective metal, which means your jewelry will be protected for a lifetime of wear. Platinum does not change shape or wear away so precious stones are held firmly and securely. The density of platinum makes it more durable than other jewelry metals.
Clean platinum in the same way you clean other fine jewelry to maintain its fine appearance and ensure that it lasts. Either use a mild solution of soap and warm water, and gently rub it with a soft cloth, or buy a jewelry cleaning solution.
