Gold is not only the precious metal currency of all countries, but also occupies an important position in the consumer market for a long time. Jewelry made of gold has been the first choice of many people throughout the ages. When buying gold jewelry, you must have heard of "purity", "18K", "alloy" and "standard" and many other terms. Today, Yiheng takes you into the world of gold and sees the different countries for gold. What are the keywords? 1, purity The purity of gold is a very important consideration when buying gold jewelry. The purity of gold "caratage" means the percentage of real gold in any piece of jewelry. 24K gold refers to pure gold, which is soft and flexible, but also easy to deform and wear. This is why pure gold is less used in the production of finely designed modern jewellery. Adding a small amount of other metals, such as silver, copper, and zinc, to pure gold can improve its practicality, durability, and color. 2. Popular gold purity Gold jewelry has different purity. The preference for gold purity is usually based on cultural, regional or traditional factors. For example, 22K gold is mainly used in India, while 21K gold is well received in the Middle East. Most Europeans like 18K gold. The 24 carat K gold, pure gold, is mainly used in East Asian countries and is often used as a tool for investment or exchange. 3, "purity code", the United Kingdom is different The “Carat Code†in the UK Quality Mark will indicate how much pure gold your jewellery contains. The word "carat" comes from Arabic, meaning "bean seed" because many years ago, seeds were used to measure the weight of gold and precious stones. Now, literally, the number of carats in gold refers to how much real gold a piece of jewelry contains. For example, pure gold is 24 carats or has a purity of 99.99%. 4, alloy Many of today's gold is blended with a specific proportion of alloys - alloys can change the color and hardness of gold, making it stiffer and stronger. The carat logo will tell you the ratio of pure gold to alloy. The greater the number of carats, the greater the proportion of pure gold. The minimum carat standards vary from country to country. For example, the minimum standard in France and Italy is 18 carats of gold, Germany is 8 carats, and the United States is 10 carats of gold. But after the First World War, the UK's minimum gold standard reached 9 carats due to insufficient gold supply. 5, the British gold standard Traditionally, most jewellery is used in the UK in 9 carat gold, although there are also 14 carat, 18 carat, 22 carat, 24 carat gold standards. You will find that 9 carat gold (37.5% pure) is shown as 375 in the quality standard (9 parts pure gold than 15 parts alloy). The mark 585 is shown on 14 carat gold (58.5% pure) (14 parts pure than 10 parts alloy). The logo 750 is shown on 18 carat gold (75.0% pure) (18 parts pure gold than 6 parts alloy). The mark 916 is shown on 22 carat gold (91.6% pure) (22 parts pure gold than 2 parts alloy). Pure gold is defined as 24 carats or 99.99% pure. It is generally believed that 9 carat gold is harder and more durable than 18 carat gold, but in fact the 9 carat and 18 carat gold are the same. 6. Gold flags of the United States and Europe In the United States, "Karat" and "K" measure the purity of gold. “Carat†and “C†measure the weight of a gemstone. The K mark tells you the relationship between pure gold and alloy. European carat marks: 999 for 24k gold, 750 for 18k gold, and 585 for 14k gold. There are also signs that contain other meanings displayed on fine gold jewelry. SHAOXING JUNCOO TRADING CO.,LTD , https://www.sxjuncoo.com
