**Distinguish between true and false: look at the color, look at the mark, look at the hardness, listen to the sound, weigh the weight.
1. Look at the color. According to the different luster and color of **, you can roughly distinguish pure gold, K gold, real gold, fake gold. The old jargon handed down from the pawnshop, "seven green, eight yellow, nine five red, yellow and white with gray and half gold" is to describe the purity of **, the color is green and white, the purity is not high, and the color is red and yellow, and the purity is high.
2. Look at the mark. Domestic ** jewelry is marked with a kill mark in accordance with the regulations, marked with 24k means that the purity is above, and 18k is marked with a purity of more than 75%.

More than 97% of the ** jewelry, after bending two or three times, wrinkles appear at the bend, also known as fish scale patterns; About 95% of the ** jewelry in color feels hard when bent, and the fish scale pattern is not obvious; About 90% of the color of ** jewelry, when bent is very hard, there is no fish scale pattern; ** jewelry with more impurities will be broken after bending two or three times; If it is made of raw gold, it is broken when bent, and the section has obvious sand grains.
4. Listen to sounds. When real gold with a fineness of more than 99% is thrown on hard ground, it will make a horn sound, with no rhyme and no elasticity. Fake or low-color** sound is brittle and no dullness, generally makes a "dangdang" sound, and the sound has an aftersound, and beats violently after landing.
5. Weigh the weight. **The specific gravity is that the fineness has a greater relationship with the specific gravity, and when the specific gravity is close, the higher the pure gold content. The weight of the weight is proportionate to the size of the volume, and the shape is large and light, which may be adulterated.
But generally in the hand, if there is a slight sense of heaviness, it can be perceived as real gold jewelry, which shows that the ** body is small and heavy. Be vigilant against bulky and light jewelry, and carefully distinguish whether it is a fake or a semi-counterfeit.
