Abstract
A gold alloy that is usable for jewelry and other applications. The gold alloy is made by combining Y % gold with Z % of a master alloy, wherein Y+Z=100. The master alloy includes 16% silver, 71.771% Copper, 12% zinc and 0.229% X, wherein X being selected from the group consisting of silicon, germanium, or mixtures thereof. The gold alloy may be made by first forming the master alloy and then mixing the gold with the master alloy. The gold alloy may also be made by mixing gold with the elements of the master alloy without first forming the master alloy.

A method of forming a gold alloy comprising the steps of:
- adding Y % gold;
- adding ZAg % silver, wherein ZAg=(1600−16*Y)/100;
- adding ZZu % zinc, wherein ZZu=(1200−12*Y)/100;
- adding ZCu % copper, wherein ZCu=(7177.066667−71.77066667*Y)/100;
- adding ZX % X, wherein X being selected from the group consisting of silicon, germanium, or mixtures thereof, wherein Zx=(22.9333−0.2293333*Y)/100.
