Gold shows its colors

Elegant red, popular rose or classic shades of yellow gold — how are the many fine nuances of gold created? Why do alloys with other metals play a role in these nuances? We’d like to show you how this incredible range of colors is created and reveal how various metal alloys help our casters achieve the most subtle shadings.

01

Pure gold does not melt until its temperature rises above 1,000°C. Nonetheless, at room temperature pure gold is too soft to reliably maintain its original shape and appearance over the long term. This is why our casters alloy gold with other metals such as silver, copper or palladium.

In Germany the fineness of an alloy (i.e. the content of the most precious metal it contains) is always expressed in terms of parts per 1,000. For example, an alloy that is 75 percent pure gold is expressed as 750 parts per 1,000 (18 carat gold).

03

The composition of the remaining metals in the alloy makes it possible to create a broad spectrum of desired colors and nuances. The color accents of rose gold are primarily created with copper. Yellow gold, one of the most popular gold alloys, is the result of combining pure gold with silver, copper, and zinc.

 

04

The white color of white gold was formerly created by adding nickel. After more and more cases of nickel allergy came to light, jewelrymakers switched from nickel to palladium, a chemical element in the platinum group.

Here you can discover the colors, variety, and creative inspirations engendered by gold.
