What is K gold: "K" is an abbreviation for "Karat" and "Karat" is a rewrite for "Carat". "Carat" (transliteration "carat") originated from a carob tree on the Mediterranean coast. The tree is 12 to 15 meters high. Whenever planted, the beans are about 15 cm in size (imperial). In ancient times, people used this bean kernel as a weight measurement weight. Along with the habit, it becomes the unit for measuring the weight. In 1914, the international standard weight of "Cela" was 0.2 grams. In order to distinguish the gold "carat" and the gem "carat", people changed the English "Carat" which represents the weight of gold to "Karat", abbreviated as "K", as a method to measure the gold color in the world. The method calls pure gold 24K, 1/4 of pure gold is called 1K (about 4.166%), 14/24 is called 14K... It forms 24 grades from 1K to 24K. K gold is an alloy of gold and other metals. K gold jewelry is characterized by low gold content, low cost, and can be made into various colors, and the hardness is improved, and it is not easy to be deformed and worn. K gold can be made into various colors according to needs. There are various colors of K gold jewelry popular in the world, and the common ones are yellow white rose red. The most common "18K gold" in the Chinese market, its gold content is 18 × 4.1666 = 75%. I often hear people say Platinum, what is Platinum? White gold or platinum? Platinum: Platinum (Pt) gold, the natural element "platinum" is a rare precious metal element in the earth's crust, chemically more stable than gold. According to the national precious metal jewelry standard, only platinum can be called platinum. The “Pt900†or “Pt950†seen on the jewelry store's products means that the platinum content of the jewelry is 90% and 95% respectively. The purity of platinum jewelry is not indicated by “Kâ€. Will 18K gold fade? Since the process of preparing and processing K gold jewelry is very mature, the common k gold on the market has good chemical stability and will not easily change color, especially yellow K gold. However, the white K gold and the color of the K gold such as the rose after a long time of wearing, or contact with the hard object, the color of the coating will slightly fall off, showing a yellowish color, or uneven color, some people think this is gold The cause of insufficient color. In fact, the discoloration or fading of K-gold jewelry is closely related to the sweat of the human body. 99% of human sweat is water, and about 1% is waste and harmful substances in the human body, such as: chloride, lactic acid, urea, urea ammonia. When these materials come into contact with silver and copper in K-gold jewellery, they produce a chemical reaction that produces silver chloride and copper sulphide, and exhibits deep black chemical salts, which are the main cause of discoloration of K-gold. This chemical salt will fall off the K gold jewelry, contaminating the wearer's skin, leaving a very noticeable black stain on the skin. Secondly, the contact of cosmetics with K-gold jewelry will also cause a chemical reaction. Long-term exposure will cause discoloration of K gold. Gold-plated: Gold-plated jewellery is marked "GP" or "KP". It is based on the principle of electrolysis to coat a very thin layer of gold on the surface of jewelry made of silver or copper. Package gold: commonly used KF. The gold foil is wrapped on the surface of a metal material such as silver or copper. (Specially, after the implementation of the new national standard after May 2016, the labeling and naming of thousands of gold and 10,000 gold are not allowed) In the domestic market, consumers generally believe that the higher the gold content, the better, they all prefer the gold jewelry, and describe other things will also be expressed in terms of gold content (like a certain university with high gold content). K gold in the domestic mainland market, whether it is a variety of bracelets, chains, pendant jewelry, jewelry bracket inlaid jewelry, are mainly 18K. In Hong Kong, Macau, Taiwan and Western Europe, North America, jewelry inlays are mostly 9K, part 14K. (exclusive to American K Gold) In terms of value preservation, the higher the gold content, the higher the recovery price. K gold is mainly reflected in the craft, but with the development, gold and silver and other precious metals slowly become jewelry, people will slowly change into the pursuit of fashion and like to wear K gold jewelry. K gold maintenance: 1. Avoid direct contact with high-volatility items such as perfumes and hair gels. 2, to avoid contact with chemicals, such as detergents, nail polish, etc. 3, remember to remove the jewelry when swimming, to avoid chemical changes in the surface layer after exposure to sea water or pool water. 4. If the K gold jewelry after wearing is tarnished due to stains and dust, just soak and clean the K gold in a neutral detergent diluted with warm water, remove and dry. 5, often wipe with a flannel to maintain the gloss of the K gold surface.
