Gold is one form of jewelry that never goes out of style and is as popular as ever. Pure gold jewelry doesn't stain or stain like less alloys. Usually, if a person has a problem with their skin, it is due to their body, not sleeping. Gold is very delicate and can be made into any shape, including short hair such as strands and thin sheets. One of the most important things that most people look for while buying gold jewelry is cleanliness. The jewelry industry has a global system to identify this factor. Your finger ring may be marked 18K, 14K, or 10K, with K standing for karat, a system used to describe the percentage of pure gold in an item. The higher the carat number, the higher the percentage of gold in your gold jewelry. K 24K gold is pure gold. K 18K gold consists of 18 parts gold and 6 parts of one or more additional metals, which make up 75% of the gold. K 14 K gold consists of 14 parts gold and 10 parts of one or more additional metals, making up 58.3% of gold. K 12K gold consists of 12 parts gold and 12 parts one or more additional metals, which make up 50% of the gold. K 10K gold consists of 10 parts gold and 14 parts one or more additional metals, making up 41.7% of gold. 10K gold is the minimum carat known in the United States as "gold". Gold jewelry in Europe is represented by numbers indicating the percentage of gold: K 18K gold is marked as 750 which represents 75% gold • 14K gold is marked from 585% to 585% Goes • 12K gold is marked 417% to 417%. Your gold jewelry must have a mark or trademark identifying its manufacturer. The country of origin of the item may also be included. You'll find examples of pure gold jewelry, but pure gold is fragile and practically impossible to wear for everyday wear. Other metals may be added to make it more durable (and reduce its cost). Solid gold is durable, so it's a great choice for jewelry that you'll wear regularly. If you are allergic to nickel or other metals, choose products with a high gold content, such as 18K or 22K gold jewelry.
