The price of diamond rings is influenced not only by the quality of diamond and the material of prayer rings, but also by the workmanship of diamond rings. How do you see the workmanship of a diamond ring?
1. How do you see the workmanship of a diamond ring? Check whether the diamond is firmly embedded. In order to keep the diamond from falling, it is necessary not only to secure the diamond, but also to leave the gap between the diamond and the metal.
2, the diamond ring shape is in line with the requirements of the designer?. If the designer’s diamond ring requirement is symmetrical, the pattern and shape can not deviate from the center, or two symmetrical, or symmetric, must not appear symmetrical on both sides of the rough or inconsistent size.
3, whether the metal surface cracks and the internal surface is bright and clean. Improper casting, welding, and quality of the alloy can leave these marks. A fine diamond ring will not leave a rough surface, nor will it have uneven edges.

The method of examination is to wear the ring first on the little finger, to keep it loose, and gently shake it, so that the lower end of the finger with the ring face does not turn flat
Diamond ring how to clean, diamond ring cleaning is usually very important, because this is directly related to color and other issues.

How to identify diamond grades? In the jewelry market, there are all kinds of diamonds, and how to distinguish a diamond grade is the main problem in diamond trade.
How to identify diamond grades? First of all, the identification of diamond grade should be considered in four aspects:
1. color: diamond color grades are divided into D-E, F-G, h, I-J, k-l.
2. clarity: Diamond clarity level from high to low, detailed can be divided into FL, if, vvs1, VVS2, vs 1, VS2, SI1, SI2, Si3, P1, P2, p3. The less inclusions of diamonds, the more refracted the light, and the more dazzling diamonds are.
3. carat weight: the diamond price is proportional to the square of the carat weight of the diamond in the case that the other three standards are the same. The bigger the diamond, the rarer.
4. Diamond Cut: cut to give second lives, because from the unknown to the public stone fire color into a gorgeous diamond, all by cutting technology. Cut refers to various ratio and cutting parameters of diamond.
Diamond rating is a factor in determining diamond prices. The higher the diamond, the higher the price. Then we were called to the naked eye color, clarity, cut and carat weight?

Diamond fluorescence level
About 50% of diamonds produce fluorescence under ultraviolet radiation. The color and intensity of diamond fluorescence have some influence on the appearance of diamonds, and sometimes even affect the price of diamonds. This is the significance of diamond grading. The following describes the diamond fluorescence level.
Most diamonds have more or less a little fluorescence. In the grading certificates of international diamonds such as GIA, the fluorescence levels are indicated for your reference. According to the standard on the GIA certificate, the diamond fluorescence grade is divided into:
1, none (none)
2, faint (weak)
3, medium, blue (medium blue) or medium yellow (medium yellow)
4, strong, blue (strong blue) or strong yellow (strong yellow)
Although it is a natural diamond fluorescence index, but in the international diamond market, its value depends on the level of 4C, the international diamond quotation no diamond fluorescent this option in our daily life, can not see the diamond fluorescence. When we pick a diamond, we can choose the diamond as long as the 4C is up to its standard.
Of course, superior diamonds only use diamonds without fluorescence and diamond fluorescence. The diamonds in the fluorescence category are blue. They also have strict requirements for the position of the inclusions. Only the diamond with the inclusions in the surface can not be used
