It is certainly possible to increase the size of the ring, but you should always consider whether or not the silver piece has a rhodium coating. Rhodium darkens when heated.

If this happens, the defect is repaired by rhodium-plating.

Uncoated silver jewelry can fade from heat, then it will need additional treatment.

Gold is a soft metal that lends itself well to a variety of work.

To stretch a gold piece at home, you will need a metal cone of the right size, foil, a torch, and a rubber mallet. The ring is strongly heated with a burner, then put on the cone, pre-wrapped in foil. The mallet should be easily tapped on the decoration, achieving the desired diameter.

The method enlarges the ring up to 3 sizes. But if you are not sure of the result, it is better to consult a specialist.

Customers often wonder how to stretch a ring that has become out of size? Modern equipment allows both increasing and decreasing the diameter of the jewelry. This is one of the most common services provided by jewelry shops.

It is not recommended to roll the products yourself. Without proper skill, it is easy to damage the ornament. The procedure is quite inexpensive, so you will save time and avoid possible defects.


I began to wonder if it was possible to increase the size of the ring on my own. It turned out that there is only one homemade "recipe" - using a burner and a cone. Using this method, I was able to roll out the white gold jewelry by half the size. It had no effect on its appearance.

I asked the jeweler to increase the diameter of two rings. After examining one of them, the jeweler refused to do the work, saying that the jewelry is brass with gilding. The second red gold ring was enlarged in half an hour. I am very happy with the result.
