Can the ring be resized
The size of the ring holder can be adjusted. The size of a diamond ring can be changed through some methods, and there are also many merchants who offer free ring changing services. However, not all diamond ring holders can be changed in size. Some simple styles of diamond rings can be changed in size once, as too many changes can have an impact on the ring itself.
For some styles that are more exquisite or have diamond rings set on the ring arms, it is not recommended to change the size of the ring, as it can easily damage the ring holder itself.
