If the ring is too big, consider winding a circle of silk inside the ring to protect the ring and change the size of the hand. If it's too small, you can go to the jewelry store to change the ring. The process of changing the ring is not complicated. Open the ring with pliers, then add some platinum according to the size of your hand, and then polish it smooth. The whole process takes no more than an hour.

Trade in the old for the new, or change the style of the ring holder. Now many jewelry stores offer this service, just make up the difference. If your diamonds are of good color, it is worthwhile to do so. If the color is not good, you might as well buy a new one.
