Winding the thread to make it smaller: the older generation often used the method of winding the ring with red thread to adjust the size of the ring. If the ring you buy is too big, you might as well follow this method and choose a transparent fishing line to wrap around the inner ring of the ring to make it smaller, which can play a role.

Smaller washer: Technicians from professional jewelry stores or luxury maintenance agencies will make a washer with the same precious metal as the ring and put it on the inner wall of the ring, thus reducing the size of the ring. Gasket methods can be divided into local gasket, integral gasket and movable gasket. This method not only won't cause any damage to the ring, but also has a wider scope of application. Is the most commonly used ring reduction method.

Cut gold to make it smaller: General professional jewelry technicians will also use the method of cutting gold to make a small ring, which requires cutting at the right position of the ring, removing the corresponding precious metals, and then welding and polishing. This method will cause a certain loss to the ring, and it is only used for precious metal rings with single material and few or simple diamonds.

Add gold to make it bigger: compared with making the ring smaller, there are relatively few ways to make it bigger, so it is more difficult to make it bigger than making it smaller. The common process of adding gold to enlarge the ring is to cut it in a suitable place, then add precious metals of the same material and weld and polish it. If the ring has a special shape, more diamonds or special materials, this method is not applicable.
