1, Jewelry Appraisal Bureau
You can go to the local jewelry and jade quality supervision and testing center to identify jadeite. The local jewelry agency is more authoritative. In addition, in some jade crystal wholesale distribution centers, such as Sihui, Donghai and other cities, there will also be gem testing institutions. National jade appraisal institutions mainly include China Jade Appraisal Center, Beijing Jade Appraisal Institute and Shanghai Jade Appraisal Center. These institutions have a professional team of jade appraisers and advanced equipment technology, which can accurately identify the authenticity, quality, color and texture of jade.
2. A large jewelry store
If you buy jadeite in a regular jewelry store, under normal circumstances, the jewelry store will also issue a quality appraisal certificate for jadeite, which can only be done by an authoritative organization. Moreover, the identification certificate will have the number of the certificate and the model of the jade, which can be found on the phone or website on the identification certificate.
Appearance identification of jadeite
1, color. After years of washing, the real jade has a very natural softness. Most fake jadeites are synthetic, and the color is a coquettish and frivolous feeling, lacking the restrained beauty of ancient rhyme.
2. texture. The surface of natural jadeite jade is moist and delicate, mainly oily luster or glass luster. After dropping a few drops of water on the surface, the water drops on the surface will condense into dew. The surface of fake jadeite is rough and dry, and it will disappear immediately after dripping.
3. structure. When identifying true and false jadeite, you can observe it under strong light. The texture of natural jadeite is dense and delicate, and we can see the obvious interwoven structure, some of which are clustered and some are distributed in clouds, just like cotton wool. The interior of fake jadeite is clean, or bubbles are generated.
