请教14k(请问14k怎么样)(请问14k有何特点)?

Each carat (written as "k") of gold contains 4.166% pure gold. K gold is a type of gold alloy made by mixing gold with silver and copper in specific proportions, with 24K being the purest form of gold. Generally, the higher the percentage of silver in K gold, the greener the color, while a higher copper percentage gives a reddish-purple color. K value is a rough approximation of the percentage of gold in the alloy and is often represented by even numbers, such as 24K, 22K, 20K, and 18K. 18K gold means that 18 parts of gold are mixed with 6 parts of other metals (usually silver and copper), resulting in a gold content of about 75%. The calculation formula for the gold content is K value divided by 24 multiplied by 100%, which is equivalent to K value multiplied by 4.1667%.

24K gold is considered pure gold and is often represented as "1000‰", but its actual gold content is 99.99%, or 23.988K, according to the national standard GB11887-89.
