Where is Nantong Jade Appraisal?
There are gem and jade appraisal stations in prefecture-level cities, which can identify jade and jadeite.

Identification of jadeite can go to the local jewelry and jade quality supervision and testing center, which 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.

Structure: After the jadeite is corroded by strong acid and alkali, some substances are brought in and out, and corrosion is formed on the surface and inside along the mineral crystal, resulting in internal connected cracks. Under the irradiation of transmitted light, we can see the crisscross cracks inside. Under the condition of reflected light, the corrosion pits or cobweb network structure on the surface are clearly visible.

Jade can go to an authoritative jewelry and jade appraisal institution with national qualification certification for instrument appraisal and issue an appraisal certificate. In this way, the result is exact, the authenticity is clear at a glance, and it can be foolproof.

General jewelry appraisal bureau, jade wholesale market, large jewelry stores can identify the authenticity of jade.

Jade can be identified in a regular jade shop. You can also try to test the hardness, listen to the sound or look at the texture to identify the authenticity of jade, but if you are not professional, it is recommended to go to a special institution for identification, because professional people do professional things.
