How to identify B-grade jadeite with the naked eye, I really learned it after watching it

To identify B-grade jadeite, you can carefully observe the jadeite's luster, color and surface characteristics with the naked eye.

① Gloss

The fillers added to B-grade jadeite are generally organic polymers such as resin or plastic. The addition of these organic substances will affect the luster of jadeite. Therefore, B-grade jadeite usually appears as a mixture of glass luster, resin luster and waxy luster.

②Color

Although the color of B-grade jadeite is natural, after being soaked in acid solution, impurities are removed and the base is made white, but it will also affect the green color of the jadeite, making the green appear yellowish and look very unnatural. The green distribution has a slightly floating feeling, and the original silk-like and band-like color is gradually expanded, destroying the directionality of the original color distribution.

③Surface characteristics

During the processing of B-grade jadeite, there is an obvious difference in hardness between the organic filler used and the jadeite itself, so the surface of very B-grade jadeite is prone to unevenness. Obvious grooves will appear at the original cracks, and the position of the filler is obviously lower than the two sides. Many cracks form criss-crossing "ditches".

However, it is important to note that B-grade jadeite with better processing technology has a very smooth surface and does not have the above-mentioned phenomenon, so more careful observation and testing are required.
