Antique sterling silver brooch highlighted with rose and green gold
Gold is alloyed with other metals that results in producing different colours. Rose gold is made by primarily adding copper to the gold when being alloyed resulting in the lovely warm tone to it, and today green gold is made by adding silver to the gold, however the green colour is more a soft green-yellow colour. Years ago cadmium was added resulting in a stronger colour. While never a strong green such as yellow or white gold, the tone of green in antique pieces is more pronounced.
