Green gold

Green gold is a greenish-yellow gold alloy with no added copper.

The colour is created by approaching the atomic ratio gold:silver 1:1, which in the best case corresponds to a gold content of 646, where the most distinct green tone occurs. Since in this case the silver content is already over 40%, the colour tone is relatively light. Up to a third of the silver can be replaced by cadmium, which intensifies the green tone, but reduces the favourable tarnishing properties and the melting temperature. The alloys are very soft and have little colour strength. Green gold is seldom used, usually e.g. for the depiction of foliage leaves or similar.
