What is K Gold? K gold refers to the alloy of gold and other precious metals. What is K's K? K K's K is a shorthand for Karat. K is actually a way to calculate the gold content. This method comes from the Mediterranean coast, where there is a carob tree, which grows exactly the same size no matter where it grows, so it was used as a measure of weight in ancient times. In 1914, Karat was internationally defined as the standard for calculating gold content. According to international standards, K gold is divided into 24 types. The gold content of 1K is about 4.166%, and so on, the gold content of 14K gold is 58%, the gold content of 18K gold is 75%, and the pure gold is 24K. Due to the limitation of technology, people can't extract 100% pure gold now, so the gold content of 24K gold mentioned in the market is 99.9%, which is 23.98K. Therefore, it is stipulated in the national standards that merchants are not allowed to use the non-standard standard method of 24K gold to mark the gold content. K gold as a jewelry use Although there are 24 kinds of K gold, the K gold used as jewelry materials in the world is not lower than 8K. Among the 17 K gold used for jewelry materials, 14K and 18K are the most used. Why do 18K, 14K gold have multiple colors? The reason why various kinds of colored gold appear color is because of the addition of other metal components, so that its color has changed. The more common ones are: 18K white gold composition: 75% gold + silver + nickel + platinum + zinc or 75% gold + palladium 18K rose gold composition: 75% gold + copper + silver + zinc, etc. 18K gold composition: 75% gold + silver + nickel + zinc, etc. 18K black gold composition: 75% gold + concentrated iron 18K purple gold composition: 75% gold + lead The special one is platinum, which changes its atomic arrangement order to make its reflection spectrum more uniform, but it still absorbs some light, so 18K white gold does not look so bright. In general, the bright 18K white gold we see on the market is coated with a layer of enamel. After a long time, the coating peeled off, and the jewelry gradually showed its original appearance. Will it be allergic with 18K gold? Because 18K, 14K gold is an alloy, the alloy will contain a small amount of nickel, etc., and nickel is one of the main metal species that cause allergies. It will not be allergic, but also depends on the individual's physical fitness and content, so people who are allergic to metal suggest Wear gold or platinum. Why are the colors of rose gold jewelry different? For example, for 18K gold, 18K gold is a multi-metal alloy containing 75% gold and the remaining 25% is other metals. The remaining 25% of the metal types and ratios are different and the colors will be different. The formula of each gold factory is different, so the color of the products of different manufacturers will be slightly different. The color of different batches of products may also have subtle differences in color due to the adjustment of the formulation ratio. Maintenance knowledge K gold is very stable and does not easily change color. It will not fade and change color for many years. However, jewellery is worn all the year round. The body's sweat contains various substances. Some of them react with silver and copper in K-gold jewellery to produce a chemical reaction, which produces silver chloride and copper sulphide, which can easily make the jewellery dim. In addition, like talcum powder and massage cream containing scrub ingredients, it is easy to cause abrasion with K gold jewelry, making the jewelry dull. K gold jewelry should be kept away from chemicals, such as high-volatility perfumes and hair gels, high-chlorine swimming pool water, detergents, laundry detergents, hand sanitizers, etc., which will affect the gloss of jewelry to varying degrees.
