Yellow gold and white gold are both very well known to even occasional jewelry shoppers. But what is this rose metal? This, my friends, is rose gold! This metal is also knows as Russian gold, due to the metal’s popularity in Imperial Russia and the Soviet Union. Rose gold is, of course, an alloy of gold, copper and silver (typically 4%). The copper is what gives it this warm, sensuous color. Today rose gold is often used in jewelry items that combine yellow, white and rose gold for a special effect.
