How to tell the true from the false when buying diamond ornaments? The most worrying thing about buying expensive things like diamonds is buying fake diamonds. Now there are many merchants on the market who pretend to be diamonds with zircon and transparent crystals. In order to prevent the loss of prospective diamond buyers in Fuzhou, many people and enthusiasts should learn some common methods to judge diamonds. First, touch judgment method: put the diamond on your arm or face. If it feels warm, it is a fake diamond. Because real stones don't transfer heat, no matter how you touch them, they should be cold. Second, the pencil and pen judgment method: judge whether the diamond is true or false. After wetting the diamond with water, carve it with a pencil, and the appearance of the real diamond will not leave pencil marks. Transparent fake diamonds such as transparent crystal, glass and tourmaline will leave traces. Or dip a pen in ink and draw a line on the diamond. The line of a real diamond under a magnifying glass consists of 1 dot. 3. Falling judgment method: Wipe the upper facet of the diamond clean and drop a drop of water on it with the end of a toothpick. The water spot on a real diamond will be in the shape of a small round water spot. The water stains on the fake diamonds will soon disperse. Fourth, the gloss judgment method: judging whether the diamond is true or false, the real diamond has the characteristics of single refraction, radiant light and dazzling brightness, but you can't see the pattern when you wear it on your hand. Fake diamonds, such as transparent crystals, have chromatic dispersion and low refractive index. A fingerprint can be seen through a transparent crystal, or a straight line can be drawn on a piece of white paper. Put the diamond flat on this straight line and look at this straight line through the diamond. If the lines at both ends of the diamond edge and the lines passing through the diamond are folded or deformed, it can be confirmed that it is a real diamond. If the line is still straight, it is a fake diamond. 5. Thermal conductivity judgment method: judging whether a diamond is true or false is based on the unique characteristic of the largest thermal conductivity of a diamond, and tricking the diamond thermal conductivity meter into testing. If it is a natural product, it can make the thermal conductivity meter buzz and light up a red light, which is the most accurate and portable way to judge a diamond. 6, characterization judgment method: to judge whether the diamond is true or false, the hardness of the diamond is very strong, and it is difficult to leave a notch on it with a blade. In addition, when the diamond is gently placed on the glass, it will leave obvious white marks. Fake diamonds do not have this phenomenon. Or rub the diamond back and forth several times on fine sandpaper. The ones with scratches on the surface are fake diamonds, and the ones without scratches are real diamonds. 7. Breathing judgment: Breathe into the diamond. If the water vapor on the diamond dissipates immediately, it is confirmed that it is a real diamond. If the water vapor stays on the diamond for a few seconds and then dissipates, it is a fake diamond.
