18 Carat Rose Gold

In its pure form, gold is 24 carat and has a distinct, intense yellow colour. 18 carat rose gold is represented by the ‘750’ hallmark signifying a pure gold content of 75%. Similarly 14 carat is ‘585’ with 58.5% pure gold content and 9 carat ‘375’ has 37.5%.

By mixing a variety of other metals, the concentration of pure gold is reduced to achieve a lower carat. This process is known as alloying. 18 carat rose gold (or pink gold as it is also known) is achieved by adding a high concentration of copper, which influences the colour of the metal. The characteristic reddish-pinkish colour of copper and the quantity added will influence the shade of pink achieved.

Traditionally used in vintage jewellery, the rise in popularity of this style in recent years has seen rose gold used in modern and contemporary designs, especially for rose gold diamond engagement rings.
