Rose gold is an alloy of gold and copper, and the copper gives it a reddish look. Copper is also its weak point. In ordinary rose gold, the colour can fade when exposed to sunlight or seawater. Rolex and Omega both add other metals to their rose gold to stop this.
What is the difference between rose, red and pink gold?
People often use rose, red and pink gold as if they were the same thing. What actually separates them is how much copper the alloy contains. Copper is the metal that gives the gold its reddish tint, and the more copper there is, the redder the gold looks. The alloy has had other names too. It was popular in Russia in the early 1800s and was once known as Russian gold.
Why does rose gold fade?
The copper that gives rose gold its colour is also its weakness. In ordinary rose gold, the copper can fade over time when it is exposed to things such as sunlight or seawater. Rolex deals with this by adding platinum to its own rose gold, which it calls Everose. The brand introduced Everose gold in 2005. The platinum is there to stop the copper from fading.
What is Omega’s Sedna gold?
Sedna gold is Omega’s patented 18K rose gold. It is made of gold, copper and palladium. A traditional recipe would use silver, and Omega uses palladium in its place. The palladium is meant to keep the reddish colour from fading. Omega says Sedna gold resists discolouration much better than standard 18K red gold. Like Everose, it is meant to solve the same problem: copper that loses its colour over time.
