Generally speaking, it is easier to make the ring smaller, just cut off the redundant part of the original ring and weld the two sections together. The amplifier ring is relatively complicated. Some can achieve their goals by knocking, and some must cut off the original ring and add a precious metal material of the same material.

If the ring is enlarged, find a suitable place to cut it, then gold-plated or cut it, and finally weld and polish it (of course, it must keep its shape). This method of changing the size is suitable for rings with simple structure and no special material. If the number of changes is within a certain range, such as Bulgari's spring ring, this method cannot be used.

However, it should be noted that not all styles of rings are suitable for modification. Some rings are limited by materials or inlays and cannot be resized at will.

Some rings contain special materials, such as some spring rings and Cartier tricolor gold rings with ceramics, which cannot be exchanged in this way.
