Gold jewelry does not have to identify which brand. In the selection process, as long as the purity and color meet certain requirements, it is very good gold; But when buying, we should pay attention to prevent fake and inferior products from entering our pockets, so as to distinguish the true from the false before buying. The method of distinguishing true and false gold is as follows:
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. In other words, red and yellow (yellow-red) is the best gold with a fineness of over 95%; The fineness of positive yellow is about 80%; Cyan accounts for about 70%; Yellow is light gray, and the fineness is about 50%. Therefore, there is a formula of "seven green, eight yellow, nine five red, yellow and white with gray and half gold". For a long time, there has been a saying that "copper turns green, silver turns black, and gold never changes color".
Weight: The weight of gold is about twice that of silver, lead and tin with the same volume. Real gold feels like falling in your hand, while copper or others only feel heavy and don't fall.
