In the gold jewelry market, gold is a precious metal. Many people think that gold is not just a consumer product. More people regard it as a way of investing. So how do you identify gold and gold jewelry? How to maintain, clean, and save? Look at the color According to the different luster and color of gold, it can be roughly distinguished from pure gold, K gold, real gold, and fake gold. Gold is better with gold, while the color of sand gold is a bit blue. If you have a long history of gold jewelry, there is a saying that "the copper turns green, the silver turns black, and the gold never changes color." The high purity gold is golden yellow with pure and soft color. Literacy Whether it is gold jewelry, platinum jewelry, there will usually be a gold jewelry stamp. For example, a gold ring with the words "AU" > 999 printed on the inside. If any jewelry is engraved with the English letter "GK", its content is "gold plated". Consumers should identify the authenticity of gold jewelry by identifying whether there is a seal on the jewellery, whether the seal meets the above requirements, and whether it is clear. Test hardness The higher the gold content of the jewelry, the softer it is. The hand is easy to bend, the toughness is good, and it is not easy to break. The hard things will leave a clear scratch; the lower the gold content, the harder it is, the more force it needs to bend, and It is easy to break, and when scratched with hard things, the scratches are not obvious. 掂weight Gold is heavier than other metals in comparison to other metals. The same volume of gold, its weight is 1.8 times that of silver and 2.2 times that of copper. Therefore, the real gold care should feel heavy in the hands, and the fake gold feels lighter. Gold maintenance method Gold is soft and easy to deform, so don't pull necklaces and other accessories. When you sleep, remove the jewelry to avoid deformation. If you don't wear it for a long time, apply the velvet bag and put it in the jewelry box to avoid rubbing damage with other jewelry. Chemicals such as detergents and disinfectants will change the color of gold. Therefore, gold jewelry should be removed before cleaning and swimming, so as to avoid chemical changes in the surface. Pure gold jewelry should avoid direct contact with perfumes, hair gels and other cosmetics. In the case of cosmetics containing mercury and lead, it will produce chemical reactions, which will easily lead to white spots on the surface of the gold ornaments. At this time, you can restore the original color by baking it under the alcohol lamp for a while. If you can't solve it, you can get a gold jewelry store for professional jewelry care.
