One of the characteristics of gold is its softness, so it is difficult to inlay a variety of exquisite styles, especially when it is inlaid with pearls, precious stones and jadeites. Therefore, people add a small amount of silver, copper, zinc and other metals to the gold to increase the strength and toughness of gold. The gold ornaments made in this way are also called K gold.
K gold jewelry is characterized by low gold content, low cost, and can be made into various colors, and is not easily deformed and worn. K gold is divided into 24K gold, 22K gold, 18K gold, 9K gold, etc. according to the amount of gold. The most common 18K gold in China's market, its gold content is 18 × 4.1666 = 75%, the mark on the jewelry should be "18K" or "750".
K gold can be made into various colors according to needs. There are various colors of K gold jewelry popular in the world. Everyone has yellow and white. When gold is mixed with 25% palladium or nickel, it will become white, and the main component that makes up it is gold. This is called white gold. Consumers should also pay attention when purchasing, do not confuse platinum and white gold (or K platinum). Our commonly known Platinum, its canonical name should be platinum, its purity is not represented by K and PT, such as PT950 means that the content of platinum in jewelry reaches 95%%; white K gold (K Platinum) is gold and other metal synthesis The products, white K gold, K white gold jewelry and platinum jewelry sold on the market are two completely different products.
