I am going to be making a ring from green gold soon and have decided I probably want to go with green gold. The master alloy I will be using can be used for both 14 and 18 karat, it is composed of 85% Silver and 15% copper and nothing else (homemade master alloy)
I don’t know whether or not I should go with 14 or 18K to achieve the greenest possible colour. Most refiners say their 18K mix is greener than their 14K, however I have also heard that 18K green is more of lemon yellow than a true green. I have used a 14K green composed of 58.5% gold and sterling silver which turned out surprisingly green but a bit soft. Around as soft as sterling, which would incidentally be the hardness of the 18K alloy using the 85% silver master alloy.
Anyway I digress, which would be greener, 14K it 18K?
