1. Look at the color to identify the purity of gold and gold jewelry, the deeper the color. 2. Look at the hardness of the gold and pure gold and low hardness. The nails can be used to draw a shallow mark. The teeth can be used to leave the dental print. The pure gold is soft and easy to bend. The lower the purity, the less easy to bend. 3, listening to the sound identification of the gold with more than 99%of the real gold to throw it on the hard ground, it will make a tap sound, there is no rhyme or elasticity. The fake or low golden sound is crispy and has no dullness. Generally, the sound of "Dangdang" is made, and there are surplus sounds. 4. Burning with fire to identify gold with fire, the jewelry will be burned red (do not melt the jewelry), and observe the color change after cooling. Black is not pure gold. 5. The weight of the gold and gold jewelry should have a deep fall in the hand, and the fake gold jewelry feels lightly. This method does not apply to the gold jewelry inlaid with gems.
