Silver jewelry without an appraisal certificate is like gold without an appraisal certificate. In addition, 925 is not pure silver, which means that silver with a silver content of 92.5% and above 98% is considered pure silver. Generally, all silver ornaments on the market are without certificates, but there is a very practical method to distinguish whether they are pure silver or not.

Any sterling silver jewelry will be marked with "S925", indicating that the silver content is 925 per thousand. In the industry, 925 is considered as pure silver. If you don't feel at ease, there will also be a jewelry appraisal office near the jewelry store, so you can re-examine it.

Silver jewelry processing technology;

Qi Diao Process: This is an ancient gold and silver processing process, which is common at home and abroad. Hammer the gold and silver thin, then chisel it into a relief effect, or chisel out rich decorative patterns. Generally speaking, the larger the area, the richer the effect.

Melting method: this technology is very common in Europe and is only used to make silver. The method is to use the physical characteristics of uniform and rapid heat conduction of silver, blow with fire, heat the thin silver sheet to the moment of melting, remove the heat source, and make uniform wrinkles on the silver sheet. Jewelry made of this material has strong decorative effect and natural charm.

Japanese wood grain metal: the main material is also silver, and the production method is very interesting, artistic and decorative. The method is to weld pure silver with different contents of copper-silver alloy, nickel-silver alloy, copper, brass and copper (sometimes with a little gold) layer by layer, and then knead and flatten it, so that the metal surface will have different color and texture effects.
