If you drip nitrate on the gold jewelry, there is no chemical reaction, indicating that your gold jewelry is real gold.

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.
