Types and nature of precious metal
Precious metal simply means a rare metal with low production, which is, gold (Au), platinum (Pt), silver (Ag), iridium (Ir), osmium (Os), palladium (Pd), ruthenium (Ru), rhodium (Rh), 8 eight types of metals. Any of them have excellent corrosion resistance and acid resistance, and have valuable chemical properties.
Precious metals are stamped to indicate information such as its type and purity, and stamps will be different depending on products. While for products such as ingots, stamps will be big and obviously craved, there are also stamps that is difficult to understand depending on the product, and characters that cannot be read unless you see it with a loupe etc.

In addition, besides from the metal type and purity of the ring, the size of the jewel and the brand name are also stamped. For example, if it’s a diamond, “D”, emerald is “E”, and if it’s a ruby, there is an abbreviation letter such as “R”. In addition, if zero is omitted due to space deficiency, “0.28ct”is expressed as”.28″.
