This simple, dainty ring can be made in sterling silver or 14k gold-fill. It's hammered for texture, which means it's also hardened and durable. It can be slightly adjusted, but try to get as close to your size as possible.
Your midi ring size is 3-4 sizes smaller than your usual ring size. For example, if your ring size is 7, your midi ring sizes vary from 3-4. You can try 4 sizes smaller to get a comfortable fit, and adjust the ring to be smaller if necessary.
