1. Use magnets. First of all, we need to know the work of gold. Gold is not copper or iron. If the gold jewelry you buy is firmly sucked by magnets, it can be said that such gold jewelry is not pure gold. However, there are also some fake gold that cannot be sucking with magnets, but it does not rule out that it is a real gold jewelry. You need to try the thickest part of the gold jewelry. Because the weight of gold jewelry is very expensive, for example, the gold jewelry necklace, we use magnets to adsorb in the thickest position of the gold jewelry necklace. 2. Use unlawish ceramic cup. First take off your jewelry into a glazed ceramic board. Please note that if your gold jewelry is made of real gold, then a golden stripe on the unlavic ceramic plate will be left. If it is counterfeit, it will be counterfeit. Gold stripes will turn black.
3. Use nitric acid. This is also the method used by most jewelry dealers to test it. The operation method is very simple. We first take a drop of nitrate on the gold jewelry to see if it reacts. After dripping nitric acid on gold jewelry, if nitric acid will produce a green reaction, then it is a fake. If the reaction that the nitric acid is dripped on the gold jewelry is a milky white response, it means that such gold jewelry may be a gold -plated sterling silver -plated silver -plated silver -plated silver It is not a real gold jewelry. If you drip nitrate on the gold jewelry, there is no chemical reaction, indicating that your gold jewelry is real gold.
How to identify authenticity gold, the first way to draw a few times with a needle, scratch is true. The second method is baked with a lighter. The real gold is not afraid of the fire. If you fall on the table, the sound is more dull.

On the screen, we can often see people bite gold with their mouths to test the authenticity. In theory, the color of the gully in the bite has not changed. The higher the goldenness. But we do not recommend this method because this may hurt the teeth. In addition, because lead is softer than gold, bite marks will be left on the gold -plated lead. The second method is the magnetic detection method. Gold is a magnetic metal, so it can be attracted by magnets. This method is simple and easy. Use magnets to suck the golden device. If the magnet can attract gold, it is fake. However, it cannot be attracted by the magnet alone that it cannot prove that this golden device is true, because it may also be made from other non -magnetic metals. The third method is a very professional test method. Generally, only jewelry dealers or craftsmen will adopt, that is, nitric acid testing method. Put the gold in a small stainless steel container, drop a drop of nitric acid on the goldware, and observe the reaction. If the acid is green, then this golden device is either made of ordinary metal or gold plated. Then it is gold -plated copper. If there is no response, then this golden device is true.
