  1. It should be a customer phone number applied for by a jewelry dealer. Most of the national certified testing agencies use a fixed phone number, not a 400 phone number. Because the 400 telephone is easy to apply, the recognition is not very high. Authoritative jewelry testing agencies provide network encoding query on the website. You can see if there is a testing agency certification on the tag!

  2. Henan Provincial Product Quality Supervision and Inspection Institute's Gold and Silver Jewelery Inspection Center can be turned on, just like 12315, civil servants drink tea all day to read newspapers, how can you control your phone. However, the website can provide verification services.
