Recently, I saw the certificate of diamond ring on the internet, and I can also fake it. How can we non-professional jewelry consumers see the authenticity of the certificate? In China, diamond certificates are mainly divided into GIA certificates and NGTC certificates. GIA certificate is issued by Gemological Institute of America, which is universal. NGTC certificate issued by China National Jewelry and Jade Quality Inspection Center is the most authoritative and circulating certificate in China. If you still can't tell the authenticity of the certificate, the following three methods can also help you tell the authenticity. 1, you can find some professional jewelry appraisers to help you identify. 2. You can enter your own certificate number on some certificate inquiry websites to help you identify. 3. Go to the local jewelry quality inspection department to help you identify.
After the above introduction, you will know how to distinguish between true and false. In fact, you just need to go to a regular merchant to buy it.
