1. The size of most rings can be changed to a larger or smaller size, but there are still a small number of rings that cannot be adjusted in size. For example, a ring with a hollow interior cannot be resized, and a ring with a pattern engraved on the ring cannot be resized, because adjusting the size will change the original design of the ring.

2. Many big brands provide free ring size modification services, but as the appeal said, only some special styles of rings cannot be resized. Metal has a certain degree of ductility. Generally, if the product states that the size can be changed, it will not affect the appearance.

3. Changing the ring to a ring has little impact on the ring. 1: Change the ring from large to small: This kind of modification only requires cutting off the excess part of the ring, and then modifying the ring wall. There will be no indelible loss, but some gold weight will be lost in this process. This means that you will lose some of the value of the ring itself.

4. If the ring is too small, it can be enlarged. The method of enlarging the ring is generally to add gold. First measure the ring, cut off the ring holder as needed, then add precious metal with the same material as the ring holder, then weld, grind and polish, and electroplat if required.
