Guangdong Gold, Silver and Jewelry Testing Center is an authoritative testing institution approved by the Guangdong provincial government, with independent legal personality. The certificate inquiry system of the center has undergone strict technical audit and security test to ensure the accuracy and credibility of the inquiry results.
Credible. Many certificates in the jewelry industry are issued by this testing center, including Lukfook Jewelry. The color of the certificate is blue, abbreviated as GDTC.
Generally speaking, such testing centers will not falsify, nor will they forge testing certificates, for fear that businesses will cheat. I suggest you go to another testing center, such as Guangdong Gold and Silver Jewelry Testing Center, or other authoritative organizations. Generally speaking, the inspection fee for jadeite will not exceed that of 50 yuan.
