There are two situations in which there is no steel seal on the China Quality Assurance Jewelry and Jade Certificate:

1. The certificate is forged, and it is not the real certificate of China quality assurance jewelry and jade.

2. The certificate is real, but there is a problem in the printing process, which leads to the inability to print the steel seal. I suggest you contact the official customer service department of China Quality Assurance Jewelry and Jade Certificate for further confirmation.

Jewelry and jade certificate is a certificate issued by a professional jewelry appraisal institution or certification institution to prove the quality and authenticity of jewelry and jade.
