Is a ring stamped RSG gold or fake?

A ring stamped "RSG" typically indicates that it is made of "rose gold," which is a type of gold alloy that includes copper, giving it a pinkish hue. However, the authenticity of the gold can only be confirmed through testing, as the stamp itself may not guarantee that it is genuine gold. It's advisable to consult a jeweler or use gold testing kits for an accurate assessment.
