I don't think so. Take jadeite as an example. Jade identification certificate generally includes nine contents: number, verification code, identification result, shape, total mass, color, enlarged observation, remarks, inspector and reviewer (the names of inspector and reviewer are generally handwritten).

On the back of the certificate, there are generally three nationally recognized marks (CMA, CAL and CNAS/ilac-MRA) and an anti-counterfeiting label, which is very important and difficult to forge.

The anti-counterfeiting mark on the certificate, steel seal, network query and other methods can prove the source of the certificate.
