When adjusting the split ring, transparent fishing line, red line or gold line can be taken according to the aesthetic requirements, the line is wound around the opening and tightened, and the ring is fixed after being adjusted to a suitable size, and the redundant line is subtracted to complete the adjustment of the ring. You can also cut a small piece of fine transparent thin rubber tube into a length of about 1 cm, put one end of the movable ring into the rubber tube, move the rubber tube, put this end into the joint at the other end, and finally reinforce the adjusting ring.
Other methods
There is a kind of "ring repair artifact" on the Internet, which is a commodity specially used to repair rings. Just like a transparent telephone line, it does not affect the beauty of the ring, and can also be used to slowly wrap around the intersection of the open ring and fix it. When you adjust the size yourself, it is best to have a ring stick around you, which will be very convenient to adjust. There are various types of hand inches on the finger stick, which can be adjusted directly on the stick according to the types of fingers, which is accurate and convenient.
Generally speaking, the size of rings with small hardness is easier to adjust. For rings with high hardness such as platinum and K gold, it is best to go to a jewelry store for professional adjustment. Arbitrary adjustment is easy to cause the deformation of the ring, and it is not easy to find the tools available at hand. The use of some tools may also damage the surface of the ring.
