sorelle jewelry wholesale 1. Color, the higher the goldenness of the gold, the deeper the color. The old -fashioned "Qiqing Eight Huang Jiu Chi" circulating in the pavement is the purity of gold. The color of the color is not high, and the color is red and the purity is high.
2. Weight. Gold is a heavy metal, the proportion is 19.32, and the same volume of gold is about 1.2 times heavier than copper. This is why scammers choose to use brass to cheat. The 0.2 times gap alone is difficult to detect by feel.
3. Hardness. The golden texture is soft and good for ductility, which is conducive to processing to create jewelry with different forms. This is why people choose gold making jewelry. Gold with high purity can leave traces with a bite with your teeth, while the brass is more hard and not easy to bend.
4. Sound. Because the golden texture is soft and the proportion is relatively large, there is only a sound that falls on the ground without making a crisp sound.
5. Burning. This is also a way to think of the authenticity of gold and false people. The so -called "real gold is not afraid of fire" is the truth. If the brass is put on the fire, the color will become dark, and the gold will not be, and the surface color will not change significantly.
6. See the mark. Domestic gold jewelry must be used to be killed in accordance with regulations. It indicates that 24K represents a purity of more than 99.6%, indicating that 18K means that the purity is above 75%.
