That is interesting. I remember some years ago when rose gold was introduced. There were some lovely jewelry applications. I remember buying my wife a gold necklace that had gold and rose gold intertwined. It was quite lovely actually. I most imagine this would be used much the same as a decorative feature.
My parents bought me a ring from Egypt with my name in hieroglyphics that was Rose Gold. Personally, I like rose gold better than any oher alloy.
