375 gold jewelry

375 alloy information

Gold jewelery, which is hallmarked with a 375 gold grade mark, can come in different metal shades and degrees of hardness.

9K yellow gold: 375 yellow gold alloys typically consist of 37.5% fine gold, copper and silver. The gold color may vary slightly depending on the manufacturer, the required degree of hardness, the exact color shade selected by the goldsmith and the surface treatment.

9K red gold: 375 red gold alloys typically consist of 37.5% fine gold, copper and at most only a small amount of silver. The naturally reddish copper influences the color of the alloy dominantly into red. The red gold color can vary slightly depending on the manufacturer, the required degree of hardness, the exact color nuance selected by the goldsmith and the surface treatment. In the case of lighter red gold, one also speaks of rose gold or rose jewelry.

9K white gold: 375 white gold alloys typically consist of 37.5% fine gold, silver and either nickel or palladium. The naturally metallic silver-colored silver, nickel or palladium influences the color of the alloy dominantly into white / silver. The shade of white gold can vary slightly depending on the manufacturer, the alloy composition used, the degree of hardness required, the exact shade selected by the goldsmith and the surface treatment. White gold jewelry is often coated with a thin layer of rhodium after production in order to achieve an evenly beautiful surface shine.

The hardness of 375 alloys can e.g. B. through the use of so-called spice metals such as manganese, nickel, titanium, etc. and through different processing methods (rolling, heating, quenching, hardening) for different areas of application.
