If you decide to buy a ring, find out first the exact dimensions of the fingers of the person who will wear it. The size is the diameter in millimeters. So, for example, ring 16-gauge has a diameter of 16 mm, etc.
Ask the person you are going to give jewelry, the size of his fingers or it is better to invite him to a jeweler in order not to make the wrong choice. However, if you want to give an engagement ring to his fiancée so that it did not learned, or have to measure her fingers when she's sleeping, or take it quietly for a time one of her rings or to ask the future mother-in-law.
If you do not guess the size, and the ring is too big, you will have to contact the jeweler to slightly reduce the product. Therefore, even when choosing the rings (especially engagement), do not apply an etching (for example, with the date of your proposed wedding). It's not the fact that wedding can be upset, and that decreasing the ring almost always has a small seam of laser welding on its inner side (if the ring is large more than 1 size).
Do not buy "by eye" and rings with a scattering of stones on a circle or made of alloys of different types of gold metals (white and yellow, for example). First, the procedure of reduction of the ring in this case threatens absolute destruction of the product, and, second, the case will take, not every jeweler. In a pinch, if you don't know the exact size, buy a ring with one or two stones, which are usually before the procedure of reduction is removed, to avoid damage to them, and then putting it back in.
Before you give the ring to the wizard, ask him about the possible risks, namely:
would not it be a noticeable seam of laser welding;
- do not deform the ring;
- will not darken if the metal;
- do not burst in the future along the seam ring;
- will there be a noticeable cut metal, which is made before reducing ring.
If the ring is large not more than 0.5 size, it is generally not incised and do not weld, and squeeze on a special machine. However, after that the ring can deform somewhat.
