You can, of course, ask about it in the future owner of the jewelry directly or invite him to jeweler for he chose a gift. But if you want to surprise a loved one (or more - a marriage proposal), it would have to make a number of tricks to discover the truth.
Firstly, this can ask relatives of the man, which, however, may be just do not know about it. Secondly, we can somehow try to determine the size, borrowing quietly for a short time another ring from the collection of the person to whom you wish to make a gift.
But if you are in any case not have guessed the size or you donated a ring that is too large you will have to contact the jewelry workshop to reduce its diameter. But be prepared for the fact that after the reduction on the ring can remain a small seam welding laser (especially if it needs to be adjusted more than one size).
That's why jewelers usually do not advise when buying jewelry "by eye" to make them engraved or choose a product with a complex pattern, as well as a scattering of stones (max should be 1-2 stone, which before the procedure can be temporarily removed). It will be difficult to reduce the ring so that the seam is invisible and if it was made of an alloy of various metals.
Giving the product master, do not forget to ask him about the likelihood of damage to the ring during the cropping and subsequent welding. It may be:
- Darkening of the metal;
- Deformation of the product;
- Too noticeable seam;
- Too noticeable cut metal.
The most unpleasant thing that can happen to the ring during or after the procedure reduce - it can burst right at the seam. And then you will either have to melt it, or pass as scrap.
However, if a large ring is not more than half the size it can not diminish, leaving "for growth" or in the process of securing the top to be worn by another. But if you are afraid of it sooner or later lose, you also help the jeweler. Only in this case the ring will not be any crop, no welding, and just a little bit compress on a special machine.
