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 cups. 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.

First prepare a candle, lit the candle with a lighter, and then clamp the gold with the crickets to burn it on the candle until the surface of the gold is black. Put the black gold in the cold water for cooling. Looking at the color of gold, if the gold is found to return to the golden yellow, it means real gold, because real gold is not afraid of fire refining. If it is fake gold, no matter how long it is cooled, it cannot be restored to the original color.
