So you've decided to surprise his girlfriend to buy a wedding ring for his beloved, to please my mother a surprise gift. The question remains: how do you know what size ring would be suitable? Whether it is a product of silver or gold, with stones or without, any shape and size - the size of the ring is determined by the same rules. For Russia, the size of the ring is considered to be the internal diameter in millimeters, but in European countries, for example, consider the size of the American ring circumference.
Compliance is easy to define: the geometry of the course, we know that the circumference equals the diameter multiplied by the number Pi (who has forgotten, it is equal to 3.14). Hence the formula: L = D x 3.14
But do not forget two important factors:
1. By measuring the diameter of your finger, do not forget to reserve to the ring finger is not squeezed, but it was a little "room for growth." This must be done so that the finger can change its thickness, depending on external factors (naturally, within reasonable limits). For example, in the hands of very hot weather tend to swell, increasing in size. There is a downside - if you make the stock too high, then the cold ring can fall off. In general, as in all things, be aware of the gold (or in this case, silver) in the middle. But if all you make a mistake with the calculations, do not worry. Nowadays it is possible to increase or decrease the diameter of the ring, even the size of a half.
2. It should be borne in mind that in choosing the size of thin rings (eg, wedding), and large-sized rings (or rings) is too's some difference. For wide rings (more than 8 mm) of space should be more, but for more subtle, respectively, lower.
3. The thickness of the fingers of his left hand and right - different! Yes, this is true despite the fact that visually it is almost impossible to determine. That is precisely the need to measure the finger, which will be "ringed" and it was on the arm. Despite the fact that the size of the rings in different countries indicate differently, in almost any European jewelry store you will be called the circumference in millimeters. In any case, give a table of the size of the rings in the United States, Britain (UK), Japan and Germany.
