1. 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. 2. 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. 3. 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. 4. The water support test The diamond completely washed and cleaned to make it no oil. After that, the droplets on the sample on the sample. If the water droplets can keep the sample appearance, it is stated that the sample is the diamond; if the water droplets are very good Expressing it, the sample is that the sample is the imitation of the diamond. 5. The hot guide test This method is very common. When he detects diamonds, if the instrument is displayed in the red area and makes a sound, it may be a diamond, but the current imitation products can not be tested with the hot guide instrument. It is a comprehensive consideration for diamond appraisal. The expansion data This droplet test: This test is based on the oil of the diamond (after trying the diamond surface with your hands, you will find that the diamond looks greasy). Specific method: Use oily pen to draw or write on the surface of the diamond, and when other gems or the surface of the diamonds are done on the same experiment, the oil trace will show a discontinuous drip shape. Similar to this, there is also a pencil line method in the folk, which is to wet diamond samples with water, and then draw a line on its surface with a pencil. Gem variety.

If the water vapor on the surface of the diamond is quickly dispersed, then this diamond is true. If not, then it may be fakes. This method mainly uses the high heat guidance of diamonds, and the fake diamond thermal conductivity is not as strong as real diamonds, then water vapor will stay for a long time. 2. Draw a horizontal line on the white paper, and then cover the diamond's pavilion on the horizontal line. If the line can be seen through the diamond, then this diamond is fake. If you can't see any line, this is a real drill. This method mainly uses the high discount rate of diamonds. The higher the discount rate, the stronger the reflector, and the corresponding transparency will be reduced. Therefore, the real diamond cannot see the horizontal line below. On the contrary, some counterfeit products are not high and have a strong transparency to clearly see the following lines.n3. The oil -based pen is used with oily pens such as ballpoint pen or neutral pens. A line is drawn on the diamond. If you leave clear marks on the surface, the real diamond is left. counterfeit. This method is mainly to use the oil of diamonds. When the diamond encounters oil -based strokes, the pen oil will be adsorbed on it. 4, dripping diamonds, in addition to being close to oil, also have hydrophobicity. Therefore, we determine that the true and false diamonds can drip a drop of water on the diamond. If the water droplets will not immediately spread out of the diamond, then this is the real diamond.n1 morenBleak
Quickly use the naked eye to distinguish the authenticity of the diamond. You can choose the following methods: 1. Note that the gloss of the gemstone and the scattered The diamond should show a typical diamond luster. According to the color scatteredness of the diamond (0.044), the grinding standard diamond finished product should show obvious "fire color". This type of imitation diamonds with cutting standards see the colorful light from the crown observation, and the diamond " "Fire color" is generally only blue and orange light. 2. Pay attention to the appearance of some characteristics of the diamond Due to the high hardness of the diamond, there should be no rubbing marks on the surface of the diamond. And the hardness of the generation diamond is not as good as diamonds, so wipe marks are often seen on the surface; because the high refractive index of diamonds (2.417) and the excellent cut work, when the top of the diamond finished on the text on one text, the part from the pavilion will not be able to see it from the pavilion. The word is called "reading method". 3. Pay attention to some auxiliary appraisal features of the diamond although the following features cannot directly obtain the identification results, they can achieve the purpose of prevention. The main characteristics are: pay attention to the "volume and price ratio" of diamonds. The basic feature of diamonds is that the small price is high. If there is violation, you need to pay attention. If you buy a 400mg (2CT) diamond with 3,000 yuan, you should cause doubt.
4, liquid droplet test This is based on the oilyness of the diamond (after trying the diamond surface with your hands, you will find that the diamond looks greasy). Specific method: Use oily pen to draw or write on the surface of the diamond, and when other gems or the surface of the diamonds are done on the same experiment, the oil trace will show a discontinuous drip shape. The expansion information: The maintenance method of diamond: 1. When you do housework, do not let the wearing diamond dyed oil or bleaching water, oil pollution will affect the luster of the diamond; bleaching water will be the water. Make metal spots. 2. It is not advisable to wear diamond ornaments for heavy work. Although the diamond is hard and wear -resistant, it may also be damaged if the texture is hit according to its texture direction. 3. Do not put the diamond or other jewelry in a drawer or jewelry box, because the diamond will scrape other jewelry when rubbing. At the same time, platinum jewelry should not be worn at the same time as gold jewelry at the same time. Because gold is soft, if rubbing each other, it will not only damage the gold jewelry, but also make the gold dye on the platinum, make it yellow, and it is difficult to remove it. 4. Each year, platinum jewelry should be sent to the jewelry shop for inspection to check whether the diamond and inlaid are loose and worn to renovate in time. 5, diamonds are adhesive to fat, diamonds that stick to skin fat, cosmetics and kitchen oils will lose their gloss, so they should be cleaned once a month. The method of cleaning is: Soak the platinum jewelry into the jewelry cleaning solution for about 5 minutes. After removing, use a small toothbrush to brush the diamond, then put it in the filter and rinse it with water, and finally dry the moisture with a soft cloth.

If you want to quickly distinguish the authentic diamonds with the naked eye, you can drop a drop of water on diamonds and imitation diamonds. Diamonds have the characteristics of exclusive water, so the water will form a water droplet on the surface of the diamond. And most imitation diamonds do not have the characteristics of reprimination. Water droplets will form a thin film on it. This simple way can directly identify the authenticity of diamonds.
