All About White Gold
A World War II favorite, white gold meant patriotism for that era’s marrying couples, when platinum was taken off the market for use in the war effort. Today, white gold offers affordability and fashionable fun.
White gold gets its color by mixing yellow gold with alloys like nickel, zinc, and palladium. Due to the variety of the alloys used, white gold colors will vary. Sometimes, white gold is covered with rhodium plating to create a bright, pure white finish.
White gold is available in karatages up to 21 karat; it is not possible to have 22K or 24K white gold. Eighteen karat gold is 75% pure, 14K is 58.5% pure, and 10K (the lowest karatage legally sold as gold jewelry in the US) is 41.7% pure.

Advantages and Disadvantages
White gold is a more affordable yet still durable and precious alternative to platinum. It doesn’t tarnish like silver. But some rhodium-plated white gold can “yellow” over time and may need to be occasionally replated with rhodium. However, some manufacturers are creating white gold alloys that are white enough not to need rhodium plating. Be sure to ask your jeweler about these newer alloys.
When gold is alloyed with nickel, it can be allergenic to a small percentage of wearers who have sensitive skin. In response, many refiners and manufacturers are now offering white gold that doesn’t contain nickel.
