How do Jewelers make white gold?

Answered by Jason Smith

Jewelers create white gold through a process that involves mixing pure gold with metal alloys and then plating it with rhodium. This combination results in a stunning piece of jewelry with a beautiful silvery-white appearance and warm undertones.

To begin, the jeweler starts with pure gold, which is a bright yellow precious metal. However, pure gold is too soft and malleable to be used for jewelry, so it needs to be mixed with other metals to increase its strength and durability. These other metals are referred to as alloys.

There are several different alloys that can be used to create white gold, including palladium, silver, and nickel. These alloys not only enhance the strength of the gold but also contribute to the overall color of the final product. For example, palladium can give white gold a slightly grayish hue, while nickel can create a brighter, whiter appearance.

The jeweler carefully measures and mixes the pure gold with the chosen alloy(s) in precise proportions. This mixture is then heated to a high temperature until it becomes a molten liquid. The jeweler must ensure that the mixture is thoroughly combined to achieve a uniform color and composition.

Once the molten mixture has been properly mixed, it is poured into a mold to create the desired shape of the jewelry piece. The mold is then allowed to cool and solidify, resulting in a solid piece of white gold.

However, the process doesn’t end there. While the white gold may already have a beautiful color, it is still not as bright and shiny as desired. To achieve that lustrous, brilliant appearance, the jeweler applies a thin layer of rhodium plating.

Rhodium is a precious metal that belongs to the same family as platinum. It has a bright white color and is highly reflective, making it an ideal choice for plating white gold jewelry. The jeweler carefully coats the white gold piece with a thin layer of rhodium, using a process called electroplating.

Electroplating involves immersing the white gold piece in a solution that contains rhodium and applying an electric current to create a chemical reaction. This reaction causes a thin layer of rhodium to adhere to the surface of the jewelry, resulting in a bright white and highly reflective finish.

The rhodium plating not only enhances the appearance of the white gold but also provides a protective barrier against scratches and tarnish. It helps to maintain the beauty of the jewelry piece over time, ensuring that it retains its stunning white color and shine.
