  1. 1. Look at the gloss and dispersion of light
    The polished diamonds are more dazzling than rough. At the same time, the standardized diamonds can better express its unique light with a strong dispersion color, manifested as a "fire color" with five colors and beating. Compared with the unique imitation diamonds with high decentralized colors, the scattered color of the diamond is soft and soft, and the dispersed diamonds with color machines and dazzling. However, to accurately control the difference between the scattered colors of diamonds and imitation diamonds, a large number of inspection is needed.
    2. Line diamond appraisal test
    because the cutting of the diamond is usually standardized, almost no light can pass through the process of the pavilion, so when the diamond sample table is placed on a piece of paper with black lines, There is no black line on the paper on it. The same phenomenon can occasionally appear on diamond imitation with high refractive indexes, such as artificially manufacturing titanate and synthetic golden stone, but it is not seen as needed; Say, you can see the curved black line.
    3. Harbin Qi Diamond Appraisal Experiment
    The breath of the test sample. If the water vapor of the sample appearance is quickly dispersed and it feels fresh, it is declared that the sample is diamond; The sample of stating is the imitation of diamonds. This is because of the high thermal guidance of diamonds. This is also called "breathing experiment" or "fog experiment". When doing this experiment, if the sample is small, you need to apply a magnifying glass to hold it. In addition, because the evaporation rate of water vapor is greatly affected by room temperature, this method should not be adopted in summer.
    4. Fighting Effect
    This is a diamond appraisal method that determines the relative refractive index (especially suitable for the refractive index with a refractive index of 1.80). The measurement method is to place the table or bottom of the sample on the table on the paper with the tip of the handwriting. The scale of the white word traces can be seen through the sample.
    5. Shadow diamond diamond identification
    The shadow map method is a method used to distinguish the refractive index greater than 1.81, single refractive and cutting: [to standardize the diamond -like diamond sample. During the inspection, the jewelry table must be completely immersed in the jewelry table with a diaodium methane solution. Take the shot jewelry and look at the shadow graphics projected on the white violation scene. The comparison of the shadow graphics of different products through the process can distinguish diamonds and their imitation products.
    6. The water support test
    This sample completely washed the sample to make it no oil. After that, the small water droplets were on the table table. If the water droplets can keep the sample appearance, it is stated that the sample is diamond; if the water droplets soon soon Disposal, the sample is a copy of the diamond.
    but such a large diamond ring is best to use professional appraisal methods.
