As we all know that a precious metal is a rare metallic chemical element of high economic value. Historically, Gold and silver as precious metals were important as currency.
For example, “solid gold” refers to an item that contains some gold at least 10k and is not hollowed or layered. Gold plated metal has a thin layer of gold deposited over a base metal such as copper or silver. This plating is made by electrically charging the gold to the base metal and is done by placing the base metal into a solution that contains gold and electrically charging it for just an instant. This result in a very thin layer of gold being applied that will eventually lose its brightness and color the more it is worm. This type of gold is the least expensive.
Shecy uses the national standard for Jewelry — Fineness of precious metal alloys and designation of China. for example, it defines that the precious metal named 14k solid gold should contain at least 585‰ pure gold, the 18K solid gold should contain at least 750‰ pure gold, etc.
