Appraisal method of gold jewelry
1, look at the color: according to the different luster and color of gold, pure gold, k gold, real gold and fake gold can be roughly distinguished. The old jargon handed down from pawn shops is "seven green, eight yellow, nine five red, yellow and white with gray and half gold", which is used to describe the purity of gold. The purity of blue and white color is not high, and the purity of red and yellow color is high.
2. Look at the logo: domestic gold jewelry must be marked according to regulations. 24K indicates that the purity is above 99.6%, and 18K indicates that the purity is above 75%.
3, look at hardness: high-quality gold, with pins or nails can leave traces. More than 97% of colored gold jewelry is folded two or three times, and wrinkles appear at the bend, also known as fish scales; About 95% of the color of gold jewelry is hard when bending, and the scales are not obvious.
About 90% of gold ornaments are hard when bending, and there are no fish scales; Gold jewelry with many impurities will break after two or three bends; If it is made of gold, it will break when bent, and there are obvious sand grains on the cross section.
4, listen to the sound: real gold with a purity of more than 99% is thrown on the hard ground, which will make a beep sound, no rhythm, no elasticity. Fake or low-quality gold sounds crisp and dull, generally making a "Dangdang" sound, with a lingering sound, and violently beating after landing.
