Generally speaking, the normal raw material price of S925 silver is about one gram in 2.5 yuan, and it is more reasonable in 4 yuan after being processed into finished products. If the silver jewelry is plated with a layer of palladium (Pd is used to prevent silver oxidation, and palladium is about 85~95 yuan per gram), then the price will be more expensive, about 4.5 yuan per gram.
The lowest price of S925 original silver I have ever seen is one gram from 2 yuan, so it makes sense to say that the finished product is around 4 yuan.
