Diamonds are very expensive things that are expensive for others to accept. Now with the depletion of diamond resources, the price of diamonds has also climbed. For such a valuable thing, you must purchase it through regular channels. When purchasing, you should pay attention to the authenticity of the diamond. If you buy a fake, it is really crying and crying. Although the diamonds now have certificates, they are still more reassuring, but there are also some defective products. We should know some knowledge about diamond identification. After all, know more about it and not lose it. Today, Xiaobian teaches you some simple and practical home diamond identification methods, so that fake diamonds have nowhere to hide in front of you. Pencil identification After weaving the diamond with water, scrutinize it with a pencil. The surface of the real diamond will not leave traces of pencil scratching. Transparent diamonds such as crystal, glass and tourmaline will leave traces. Pen identification Put a pen on the ink and draw a line on the diamond. The line of the fake diamond under the magnifying glass consists of small dots. Characterization The hardness of the diamond is very strong, and it is difficult to leave a mark on it with a blade or the like. In addition, a light stroke on the glass with diamonds will leave a more pronounced white mark, and the fake diamonds will have no such appearance. Drip identification Wipe the upper facet of the diamond and use a drop of water on the end of the toothpick. The water droplets on the real diamond will have a medium round water droplet shape, and the water droplets on the fake diamond will spread out quickly. Photometric method True diamonds are single-refractive, radiant, dazzling, and can't be seen on the hands. A fake diamond that is pretending to be a crystal, etc., has a poor dispersion and a low refractive index, and is visible through crystals. Thermal conductivity identification Finally, the diamond has the highest thermal conductivity. It is tested by a diamond thermal conductivity meter. If it is a natural product, the thermal conductivity meter can beep and light red, which is the most accurate and simple way to identify diamonds. . It can also be identified based on some of the characteristics of the diamond itself: 1. Single-refractiveness of diamonds The single refractive power of a diamond is determined by the nature of the diamond. Other natural or artificial gemstones are mostly birefringent. Under the observation of a 10x magnifying glass, the implied diamond is easy to see the overlapping image of the angular line and the two bottom lights at the same time. An image with overlapping bottom light can also be seen if the difference in birefringence is small, such as zircon. 2. Adsorption of diamonds Diamonds have a certain affinity for grease and dirt, that is, oil is easily absorbed by diamonds. Therefore, touching the diamond with your fingers will feel sticky and your fingers will feel sticky. This is not what any gems do. This method requires training to grasp the subtle differences. 3, the characteristics of a straight line The diamond surface is polished very smooth. Use a pen to smear ink on the diamond. If it is a real diamond, the surface is left with a smooth continuous line, characterized by a straight line. The counterfeit goods are left with lines of small dots. Observation with this method should be done with the aid of a magnifying glass 4, unique diamond shine Under roughly 100 degrees of incandescent lighting, the well-cut diamonds and counterfeit products are compared with each other, and it is easy to see which one has diamond luster. This method should not be carried out under too dark or too strong light.
