Diamonds have won the hearts of the public with the white and flawless natural beauty since ancient times. It is extraordinary to buy diamond jewelry. A complete evaluation of a diamond can only provide the most detailed quality situation only by relying on diamonds to rely on diamond identification 4C certificates. In recent years, people have paid more attention to the quality of diamonds, and the diamond appraisal certificate has become an indispensable part of the diamond production and sales industry. The diamond appraisal certificate must first prove that the diamonds measured are true. In other words, the first thing that the certificate must ensure that the diamond is a natural diamond, not an imitation product or artificial diamond. The first test in the laboratory is the authenticity of diamonds (such as hardness identification, heat conduction test, etc.). In addition, the appraisal certificate also includes the weight, color, clarity, cutting ratio, shape, fluorescent, radioactive and other objects of diamonds. These all need to be completed in the laboratory with special instruments. In daily appraisal, there are some simple and easy ways to identify diamond authenticity: 1. Line test:
On a piece of paper with a line, if the proportional diamonds can not see this line through the diamond, and the vast majority of imitation products allow enough light to pass, at least a part of the line. 2. Drop test:
The ink will leave a line when the diamond pen is scratched on the surface of the diamond. It can also be tested with water drops. On the surface clean diamonds, the water will keep the spherical shape for a long time, and the water on the imitation product will spread out in a relatively short period of time. This methods can help consumers preliminary judgment of the authenticity of diamonds, and detailed quality requires professional laboratories to detect and classify.
If you hold the drilling three stones, ask the boss if you can let me smash the glass. Dare to say that if you can smash the glass boldly, you can buy it. It is not very scientific but practical!
