But think about it, if there is so much green, why not cut off a large piece so that we can see it clearly and give you a good price! It is best not to buy such jade materials, or bargain at the standard of brick materials.

(2) Some jade raw materials have pickaxe marks, fractures or cuts on them. When illuminated by a light, they appear lovely green, but they are never polished. Such jade materials must have too many cracks, poor water quality, irregular green color or black content in the green color. Don’t dare to polish because all the flaws will be exposed once polishing? Encounter this situation. You can point out the parts and ask him to polish them before making an offer.

(3) Before jade materials, especially high-grade jade materials, enter our country’s borders, the owners leave many traces of grinding, digging and rubbing when they are looking for green on the jade materials. These traces are all areas without green, and are cleverly camouflaged with sand and glue of the same color as copper. If there are traces of artificial bumps and depressions all over a piece of jade, you should pay as much as the green you see (the value of this green after it is made into a finished product). High-end jade materials will most likely show traces of artificial polishing.

Researchers believe that some high-end jade materials contain high-quality emerald green. If they cut them with a knife and the condition is not good, they will just glue them together and sell them intact.
