Teach you how to understand jadeite identification certificate in three minutes! Don't say you don't understand the certificate.

A jade certificate is definitely a necessary condition when buying jade, but there are still many jade fans who leave messages in the background to ask about issues related to jade certificates. That thin piece of paper often hides deep tricks, and people who are not clear can easily fall into the trap of the certificate.

1. Don’t make these mistakes

1. Misconception 1: Do you need a certificate to get in? Don't be stupid!

I have always reminded jade lovers that jadeite without a certificate should never be purchased, and jade lovers have all remembered this reminder. However, some jade fans, when buying jadeite in shopping malls, ask the boss for the certificate as soon as they enter the door. Doing so is equivalent to writing the words "I am a newbie" on their face.

Certificates are indeed important for jadeite, but it is not wise to ask for the certificate as the first thing when buying jadeite. When the boss sees you doing this, he will directly classify you as the type of customer who “only recognizes certificates but doesn’t understand jadeite.” Then, it is inevitable that you will be falsely reported in prices and sell inferior products as good ones. Therefore, even if you really don’t understand the quality of jadeite, don’t ask for jadeite as soon as you enter the door. You can check the jadeite carefully first, and then ask the boss for a certificate after looking at one or two pieces of jadeite.

2. Misconception 2: Certificates that do not indicate A-grade products are fake!

I wonder if jade lovers have noticed that some certificates have the words "A-grade" while some do not. Some jade lovers believe that only natural jade will be identified as "A-grade", so certificates without the words "A-grade" must be fake. This is also a misunderstanding.

In fact, A-grade, B-grade and C-grade jade are commonly known in the industry. Many certificates will indeed indicate "Jade (A-grade)" in the appraisal results. However, some national and provincial jade certificates do not have the words "A-grade" marked on them. But this does not mean that the jade is not A-grade, as long as the certificate is valid and the appraisal results of the certificate do not include the words "Jade (processed)".

3. Misconception 3: If the origin is not indicated on the certificate, it must be fake!

Some gem fans who don’t understand certificates think that they can find out the origin of jadeite on the certificate. But in fact, according to the national standard for jewelry and jadeite names, the origin is not involved in the naming and will not be displayed on the certificate. If you see words like "Myanmar XX field" on the certificate, the certificate is definitely fake.

2. What does the certificate look like?

What should you look at after getting the jade certificate? Don't just look at it blindly, pay attention to these items on the certificate:

1. Look at the logo:

Jade certificates will have one or more of "CMA", "CAL" and "CNAL". For ordinary customers, there is no need to remember the specific meanings of these letters, but you can have a basic understanding of them.

"CMA" is the basic requirement of national law for testing and inspection agencies, which must be included in all certificates; "CAL" refers to the mark of testing and inspection agencies that have passed national quality review and approval; and "CNAL" is the mark of national laboratories, which is also recognized internationally.

2. Check anti-counterfeiting:

A genuine certificate will have a steel stamp or anti-counterfeiting mark. A certificate without these is of questionable credibility and is not worth trusting.

3. Check whether the pictures and texts match:

There will be a photo of jadeite on the certificate. When buying jadeite, pay attention to whether the jadeite you get and the photo on the certificate are the same item. Combined with the data on the certificate, see if there is too much difference in shape, size, and weight between the two. In order to sell B-grade and C-grade jadeite, some merchants will use other certificates with similar appearance to impersonate the certificates of these processed jadeite and deceive customers.

4. See the notes:

Many people will ignore the notes on the certificate. Don’t underestimate this seemingly redundant and useless item. Many times, there are many tricks hidden in it!

The trick in the comments

(1) Polishing powder residue: Although jadeite must go through a polishing process, normal jadeite will not be noted on the certificate as having polishing powder residue.

If there are such remarks, it means that some unscrupulous merchants, in order to sell jadeite with poor color or no color at a high price, use colored polishing powder to polish and dye it, and then directly wax it. In this way, the color is sealed in the wax, making it look very beautiful. Jadeite treated in this way can still be issued an A-grade certificate, but there will be a reminder in the remarks column. If you ignore the remarks, you may be cheated.

(2) Color not tested: This situation often occurs in red jadeite. If there are similar words in the remarks, it means that the red jadeite may have undergone optimization methods such as heat treatment (optimized red jadeite is still considered natural jadeite in the industry).

(3) Contains other minerals: Some A-grade jadeite certificates have the note "Contains other minerals" on them. This means that although this jadeite is natural jadeite, it contains a lot of impurities and associated minerals and its purity is not high. Its value is definitely not as good as jadeite without such a note.

Warm reminder: Jade certificates are actually not that complicated, just pick out the key points and read them~
