When we buy jade, we want to buy natural A-car jade, but the B-carved jade that has been processed on the market is endless, so how to identify B-car jade has become a big problem for us. B goods jade is the jade formed after pickling injection, although it looks good, but in fact the price is far less than the A jade.
Comparison of the three emeralds of A, B and C
A goods jade, refers to the natural jade without any artificial treatment, the color of jade is natural, uneven, and some colors are excessive. Under strong light transmission, the jade color will have a "color root", and the texture of the fly wing will be seen on the polished surface.
B goods jade, is the jadeite treated by pickling injection, although the surface is very good, but there is a gel, more impurities, turbid color, dull sound, the white fluorescent light will be filled under the UV lamp.
C goods jadeite is a type of jade that has been dyed. Under the light, the color is not evenly distributed. The inner filling is distributed in a network. The color floats on the surface, and the light is lightened.
Specific identification of A goods, B goods jade
1, gloss contrast
Natural A goods jade is generally glass luster, warm and transparent, strong reflection; while B goods jade is a "resin" luster, although it looks very good transparency, but the gloss is dim, it seems no spirituality.
The natural A-car jade color naturally has a layered feeling, and some are obviously excessive; the color of the B-car jade is too bright or the color is somewhat yellowish, unnatural; the green distribution of the C-car jade is even, not excessive.
3, surface structure comparison
A goods jade surface is smooth and bright, with inlaid, interwoven connection structure, it seems to be orange peel; B goods jade because of strong acid corrosion, so under the magnifying glass can see some network of acid etching or some injection cracks .
4, the contrast of the ground
The natural A cargo jade has a strong penetrating power and is crystal clear. The jade has a "flies" structure inside, and the reflection is very strong; while the B-ember jade structure is loose, the light penetration is weak and relatively fuzzy.
5, certificate comparison
The last thing I have to say is the jade identification certificate. If you can't worry about the above methods, then you can only rely on the appraisal certificate. The appraisal certificate will have the appraisal result of jadeite, whether it is A goods or B goods. See you know.
