It depends on the specific physical object.

In order to judge the authenticity of jewelry, we can't jump to the conclusion that it must be a fake.

If it is jewelry with national inspection qualification certificate, you can rest assured of its authenticity.

The authenticity of jewelry depends not only on the brand, but also on the physical state of jade and the authoritative testing data of the laboratory.

If you have any questions, just ask.

I hope the answer can help you.
