What is the difference between platinum and white gold?
Platinum is a naturally white metal that will never lose its brilliant luster. White gold is an alloy created using yellow gold. White gold looks similar to platinum, but it usually needs to be frequently plated over time to maintain its white color, adding additional expense.
Why is platinum more expensive than gold?
Platinum’s rarity means that its price is invariably higher than that of gold. The process of making a piece of platinum jewelry also requires a higher level of craftsmanship.
