Platinum & other metals

What is the difference between platinum and white gold?

Platinum is a naturally white metal that will never lose its brilliant lustre. White gold is an alloy created using yellow gold. White gold looks similar to platinum, but it usually needs to be replated over time to maintain its white color, adding additional expense.

How do I know that a piece of jewelry is made of platinum?

All platinum jewelry is hallmarked. There are a number of symbols or marks that have to be displayed on a piece of jewelry to indicate that it is high purity platinum. Here are some examples of the platinum marks to look for:

How can I distinguish platinum from other white metals?

Platinum is denser than gold, so an identical ring made in platinum rather than 14kt gold would be around 60% heavier and 40% heavier than a ring made in 18kt gold.

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.
