White gold is not a naturally white metal. It is yellow gold alloyed with other metals to achieve a white look. The white colour is often further enhanced by plating the piece with rhodium. This plating could wear away, revealing the yellow-grey colour underneath.
Platinum on the other hand is a pure and naturally white precious metal which never wears away. It is more precious than gold, whether yellow or white.
Platinum jewellery is 95% pure platinum compared to 18k gold / white gold jewellery which is 75% pure gold.
You can tell the difference between platinum and white gold by their weight. Platinum is a dense metal and weighs 40% more than 18k white gold. Even a simple platinum wedding band is noticeably and reassuringly heavier than the same ring made of white gold.

All precious metals scratch, and platinum is no exception. It is unique in that the metal is only displaced, not lost. Have your platinum jewellery polished if you are interested in maintaining a high shine. Look for an authorised platinum retailer for all adjustments, resizing, polishing and cleaning.
Store pieces separately, in a jewellery box or chamois bag so they don’t get scratched by other items.
Clean platinum in the same way you clean other fine jewellery 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 jewellery cleaning solution.
