Second, the following is more detailed!

Humans knew about the existence of gold as early as 6000 years ago and used it as an ornament. At present, the popular gold ornaments in the international and domestic markets mainly include pure gold, K gold, gold plating, gold plating, imitation gold, color-changing gold and so on.

Pure gold jewelry is made of pure gold. As the saying goes, "there is no shortage of gold", which means that the content of pure gold is less than 100%. In fact, 99% and 99.9% of gold are called pure gold products. This kind of pure gold jewelry is soft in texture, red and yellow in color, and will never pan-color. However, it is easy to deform and wear, and it cannot be inlaid with all kinds of exquisite gems.

K gold is to add a small amount of silver, copper, zinc and other metals to gold to enhance its strength and toughness. In order to express the gold content in K gold, K value is often used. The gold content of 1K is about 4. 166%. The gold content of 24K is about 99.99%, so it is pure gold. Generally, the materials used in gold jewelry are 22K (gold content is about 9 1.65%), 20K (gold content is about 83.32%), 18K (gold content is about 74.98%) and 14K (gold content is about 58.2%). K-gold jewelry is simple to renovate, and can be inlaid with all kinds of diamonds, emeralds, pearls, precious stones and carved saws to create all kinds of exquisite patterns. Most diamond rings with diamonds are 18K gold. The tip of the gold pen is written with "14K" or "14K", which means that the tip of this gold pen is 14K gold.

Gold-plated jewelry is made of copper, silver or alloy, and the surface is plated with a layer of 24K gold, which has the same appearance as pure gold jewelry. But the electroplated metal is not durable and will be worn away after a long time.
