    It is difficult to distinguish the authenticity of diamonds with the naked eye. It mainly depends on whether there are professional identification certificates
    The introduction of several diamond identification methods:
    Methods
    , Its crystal structure can be regarded as a tetrahedron combination connected to the top of the corner, repeated and three -dimensional arrangement. Diamonds composed of tetraonal bodies are common in cube, octagonal, and diamond -shaped duodenal crystals. The surface is smooth and flat, forming a mirror -shaped, and there will be no smooth pattern or grooves. Those with smooth texture or grooves are imitation.

    Methods 2
    This Edit Diamond Hardness is extremely high. You can observe the waist of the diamond. If it is a sand -like waist, it is most suitable for this method. Because the diamond is harder than any imitation, it will not appear thin stripes like imitation. R n
    Methods three
    The same because diamonds are harder than imitation products, the face lines of imitation products are often more dull than diamonds, and diamond's face line must be sharp. Essence
    Methods 4
    The principle of rigidity of diamond ratio ratio of imitation products, aspect wires of imitation products often wear out.
    Methods 5
    If diamonds have natural faces, there is a chance to find the unique "triangular growth pattern" of diamonds on the natural surface.
    Methods 6
    . If the diamond appears, the appearance is usually staircase, and the imitation products will be completely different in arcs or shells.
    The method
    The gravity test method
    The proportion of the proportion of gemstones on the market; we can use a 3.32 specific solution to test the true and false diamonds. The proportion of natural diamonds is 3.52, and all natural diamonds will sink in the gravity water, so all gems floating on the proper liquid can be certain that it is not a diamond.
    This observation method
    The diamonds have a high discount rate, and the higher the diamonds with a higher discount rate, the stronger the light reflection force, and the lower perspective. You can prepare a piece of paper with a straight line, and the two unknown diamonds to be determined are facing down, covering the straight line. Straight lines are definitely not natural diamonds.
    The parental method
    diamonds have a "oil absorption" for fat, and imitation diamonds have no such characteristic. Put the diamond with a small amount of oil on the face and rub the diamond with your thumb. The thumb will feel a kind of sticky, not easy to slide, and imitation diamonds will make the thumb feel smooth [1].
    This test
    The natural diamond heat transfer ability is good, and the heat is scattered fast. The diamonds that are about to be tested are close to the mouth, gently breathe, so that the tested diamonds are covered with a layer of light mist. At this time, the diamond fog volatilizes immediately. If it is a natural diamond, the fog will immediately dispersing. It will be dispersed for a while to imitate the diamond.
    metrics and weight
    1 Natural diamonds of carats are about 6.50 mm (0.65 cm). Most counterfeit diamonds are at the same weight. difference.
    The growth point
    In observing under the magnifying glass, there are often grooves and triangular growth points on the crystal surface of the real diamond, and there are three categories: ① ordinary glass with aluminum oxide, due to the refractive index and color dispersing Improve, easy to enter, but low hardness. ② Use chemical sapphires and colorless spinels to imitate, and the hardness is close, but the refractive index is low and there is a dual refractive phenomenon. It can be seen under the magnifying glass.
    If artificial oxidation 锆 imitation
    has high hardness and good refraction, but it will reflect more color light when rotating. Compared with the real product when rotating Obvious differences.
    The hardness test
    diamonds are the hardest natural production substances. There is nothing to draw on the diamond. If you can draw traces, it is by no means diamond.
    The heating test
    The breath at the same time on the defense diamond and other similar items. If the diamond is the surface, the water mist on its surface should evaporate faster than the water mist on other items. This is because the diamond It has high heat -conducting reasons.
    Observe the reflection light
    This can observe a very thin matte and glitter reflex light at the waist circumference of the diamond. The characteristics of diamonds are unique.
