I have been making questions about alloys of green gold with good working properties and good green colour. Now I am looking for the same information on yellow gold. More specifically what sort of alloys yield a rich but not too coppery looking alloy in 18k?
Would the traditional 18k of 750 pure gold, 125 Pure silver, 125 pure copper be a good choice or would it be more advisable to go with a more silver rich, green tinted alloy instead? Or the other way and go with a more copper rich alloy?
I have seen alloys ranging all the way from 19% of silver to 17% of copper. Which of these would give the results of a richly yellow but not too dark 18k Yellow Gold Alloy with good mechanical working properties?
