Many people subscribe to the rule that says you shouldn't mix metals. And sure, you do you, but that rule isn't actually a rule that you need to follow. Stacking rings is all about personal style and creativity. You can freely combine gold, silver, rose gold, and other metal finishes to craft a look that's uniquely yours. The key is to have fun with it and balance your stack in a way that feels right to you. Try coordinating different textures and gemstones, or play with varying ring widths to add depth. Just remember, when stacking rings, the only real rule is to express yourself!
