Resizing
There are four known methods for sizing any ring - the first of which is simply using a ring stretcher to stretch the ring to a larger size. This can only be done on plain wedding bands that have no stones in them. Stretching any ring many sizes can result in thinning of both the thickness and width of the band.
The second method is also used solely on plain wedding bands. The ring is first placed in a cylindrical bowl that is a size smaller than the ring. Then, with a flat-shaped tool, pressure is applied to an area of the ring, which compresses it. With both stretching and shrinking, no gold is added or lost in this process.
The third method, used for sizing rings up, involves cutting the bottom of the shank, pulling the two sides apart, building a bridge of new gold based on the size needed and then soldering it in - preserving the thickness at the base of the ring, where it is most essential.
The last method, used for sizing rings down, is accomplished by cutting the bottom of the shank, taking out the proper length of gold and soldering the two sides back together.
One concern that customers tend to have relates to the integrity of the side stones after a ring has been sized either up or down. The stones are always checked before and after sizing; if any of them are loose, they are tightened before continuing on to the next steps in the process. This ensures that none of them will be compromised during and after the sizing.
