Sometimes the simple things in life are the best. So, we took inspiration from the circle. This 14k yellow gold round charm feels simple, vintage, and nostalgic. A 0.4 Ct semi-precious rainbow moonstone is showcased in the middle, while a 0.025 Ct diamond hides on the back for a reversible surprise.
