Most gold rings can be enlarged or reduced in size, but there are still a few gold rings that cannot be adjusted in size. For example, a gold ring with a hollow inside cannot be resized, nor can a gold ring with a pattern engraved on it, because resizing will change the original design pattern of the gold ring.

Plain rings are not easy to change, which will destroy the pattern. You can go to their store and ask if it's a trade-in or something.

If it is a plain ring, the ring arm is relatively thin, and it may not be possible to enlarge it.

If it is a mosaic style, there are many diamonds, so it is not recommended to enlarge it.

If it is a single main stone, or there are not many styles of diamonds, the ring arm has a certain thickness and can be enlarged. However, it is recommended to enlarge it within 3 sizes, and a little gold may be needed.
