The most important of all appraisal certificates is "inspection conclusion", which is also the first of all kinds of columns in the certificate!
Natural amber has several names-amber, beeswax, blood amber, Jin Po, green amber, blue amber, insect amber and plant amber.
If the identification certificate you get says "amber" or "beeswax, blood amber, Jin Po, green amber, blue amber, insect amber and plant amber", then congratulations! This is natural, untreated amber.
Step 2 read the comments
Sometimes some optimization methods will be marked here, such as covering the surface with colorless transparent film, pressing treatment and so on.
3. What do you think of amber?
Such as "amber (treatment)" or "XXX amber" or "amber XXX" (XXX stands for the name of the treatment method, such as dyeing, color film covering, filling, heating and pressure discoloration, etc. ) appears in the "test conclusion", indicating that it is still amber, but it has undergone an unacceptable treatment method.
In the national standard (GB/T 16552-20 10 name of jewelry and jade), the treatment methods such as dyeing, color film covering, filling, heating, pressure transformation, etc. are clearly defined and listed in the "Remarks" column. You also need to pay attention when buying. Can you accept this treatment?
Step 3 look at the recycled amber
If you see such a test conclusion, you should pay attention to it: it means that this piece of amber is made of amber fragments or fragments by artificial means, which is often called "pressed amber".
At this time, please pay attention to the "Enlarge and Check" option in the certificate abstract, which will tell you the internal structure of this amber.
As the name implies, seeing this conclusion, you must have put amber back like a puzzle. If you have a "magnification check", the certificate will tell you that there are traces of splicing. The splicing material can be partially or completely amber.
4. Natural resin
Special note: they are not amber at all!
If it is stated as "natural resin" in the appraisal conclusion, it means that the fossil age of this sample is still very short, and it can't reach the level of amber.
5, imitation amber
See these words, don't hesitate, they are 100% not amber. It is an artificial material that looks like amber, such as our most common plastic family.
