There is no such thing as green gold!
There are however gold alloys which appear green.
When jewellers speak of green gold, they mean green gold alloys.
Green gold alloys are made by leaving the copper out of the alloy mixture, and just having gold and silver. In most cases, it is more of a greenish yellow, rather than what most people would describe as green.
Eighteen carat green gold would therefore contain:- Gold 75%; Silver 25%
Most green gold alloys are rather soft to be used for general jewellery purposes, but it can be used very effectively for decorative effects on hand-made pieces of jewellery.
