Welcome to CoreFacts, where we're always short on time and big on science. I'm Steve Sobieszczyk. Let's get right to it, today's question is:

What is white gold?

White gold was originally developed to imitate platinum, and is usually an alloy containing about 25% nickel and zinc. If stamped 18 karat, it would be 75% pure gold.
