When choosing diamond jewelry, it is of course best to have a professional identification tool, but usually consumers do not have this condition, then some can be identified by the naked eye. The tips are very necessary. The following 3 simple and easy-to-operate methods are shared with you, and I hope they can be helpful to you before you consume. 1. The internal refractive index of the diamond with line identification cut standard is very high, and almost no light can pass through the diamond pavilion to the table, so the bottom of the diamond is placed vertically on a piece of white paper, and the white paper is drawn with pencil black lines. The black line cannot be seen vertically through the table, and the curved black line can be seen in diamond imitations with lower refractive index, such as zircon and cubic zirconia.　　2. Gas identification 　　 The thermal conductivity of diamonds is relatively large, so we breathe out the diamonds. If the moisture on the diamond surface dissipates quickly, this diamond is a real diamond. And if the water vapor on the surface dissipates slowly, the diamond may be an imitation. However, this method is affected by the size and temperature of the diamond, and its use is more restrictive.　　3. Water drop identification　　 Clean and wipe the diamond to make sure that there is no grease on the surface. Then, point small water droplets on the diamond. If the water droplets can stay on the diamond for a long time, then this is a real diamond. If the water droplets disperse immediately, it may be a diamond imitation.　　 The above is about the method of diamond identification. The information comes from the Internet.
