It is dark because the carbon atoms in the lighter flame are not completely burned, and "carbon deposits" are formed on the surface of the ring. There are other methods for identifying diamond rings. For example, diamonds are the hardest natural generated substances. There is nothing to draw on the diamond. If you can draw traces, it is not a diamond. There is also a diamond crystal cells as a five -faced tetraonal body. The crystal structure can be regarded as a tetraonal combination connected to the top of the corner, and the rules are repeated and three -dimensional arrangement. Diamonds composed of tetraonal bodies are common in cubes, octagonal, and diamond -shaped twelve -sided crystals. The surface is smooth and flat, and it becomes a mirror. Those with smooth texture or grooves are imitation.

wholesale fashion jewelry chinatown ny How to distinguish the authenticity of diamond ring:
The trick 1: The naked eye appraisal method (1) Observing the "fire color" diamonds of diamonds is also called "fire color". Soft and cold blue light. Therefore, consumers can distinguish the authenticity of diamonds by identifying this special "fire color". (2) Whether the diamonds are sticky because the diamond has a kind of affinity for greasy, so gently touch the surface of the diamond with my fingers, it will have a sticky feeling. (3) Inspect whether the diamond or face is placed on the arm or face. If it feels warm, it is a fake diamond. Because real diamonds do not pass heat, no matter how you touch it, it is cool. Tips 2: Simple test method (1) Line tests put the diamond table down on a piece of paper with lines. If it is a real diamond, you can't see the lines on the paper, otherwise it will be the imitation of the diamond. Because the diamonds are impenetrable under normal circumstances, the diamonds cannot see the lines on the paper. (2) Natural diamonds have a strong ability to close the oil. When the oil -based pen is used to pass the real diamond on the surface, it can leave clear and continuous lines. Instead, ink often gathered into small droplets when the surface of diamond imitation is scratched on the surface of the diamond, and continuous lines cannot appear. (3) Harbin test on the diamond. If the water on the diamond disappears immediately, it proves that it is a real diamond; if the water stays on the diamond for a few seconds, it disappears before it is a fake diamond. (4) Wipe the diamonds on the fine sandpaper several times on the fine sandpaper. The marks of wipes on the surface are fake diamonds, and the real diamonds without rubbing marks.
