During the resizing process, a small amount of metal is added or removed to increase or decrease the size to fit the new size required. As a result, the ring may become slightly thicker or thinner when completed. This is a small difference and may or may not be recognizable. Resized rings are inspected by Quality Assurance to ensure that they meet our high standards and that the rings fit the required size. For free resizing, mail the ring to our office. Alternatively, if you want to stay local, you can resize directly at a location near you.
