White gold is a popular metal used in jewelry making that has a silvery-white color similar to platinum or silver. However, unlike pure platinum or silver, white gold is an alloy made by combining gold with other metals such as silver, palladium, nickel, or zinc.

The most common metals used in white gold alloys are nickel and palladium, although other metals may also be used. The ratio of gold to other metals in the alloy will affect the color and properties of the white gold. Typically, white gold jewelry is made from 14k or 18k gold, which means that it is 58.5% or 75% pure gold, respectively.

After the white gold alloy is made, it is often plated with a thin layer of rhodium to enhance its whiteness and durability. This plating may eventually wear off over time, revealing the natural color of the white gold alloy beneath.

White gold has become a popular alternative to platinum or silver in jewelry making because it has a similar appearance, is more affordable, and is more durable than silver. It is often used to make engagement rings, wedding bands, and other fine jewelry pieces.
