If the name is jade, or add a bracket, commonly known as "A goods", it means that jade is true and natural; After the jadeite of goods B and C are treated manually, they will be marked with the words "treated" or "preferred". Certificates are divided into big certificates and small certificates. Different testing equipment, different testing items, but the conclusion is equally reliable.

First, only natural A goods will issue a certificate of "jade" results. Secondly, if it is B-quality jadeite, there will be an item marked as "Jade (Treatment)", "Jade (Bonding)", "Jade (B-quality)" or "Jade (Optimization)" in the certificate. Third, the jadeite of C goods will be marked with "Jade (Dyed)".

Goods A are natural jadeite whose internal structure has not been artificially processed. If it is the natural jade of A goods, only the words "jade" will be found, and the words "A goods" and "natural" will not be marked.
