At present, there are two main mainstream materials: Au750 and PT950. Au is the abbreviation of gold, and 750, like 950, refers to the content of a precious metal. Then it is easy to understand that Au750 refers to a mixture of 75% gold and other metals. Pt950 refers to a mixture of platinum and other metals with a content of 95%. They are mainly used to make inlaid ornaments. Someone asked, which is better? Both sides have advantages and disadvantages. It's hard to say which is better. It depends on your choice. Because of its high gold content, Au will turn yellow during long-term wearing, while PT will not change color, but platinum is easy to lose shape and wear because of its soft texture.
