How to choose jadeite rough stone? What should you pay attention to when playing with raw stones?

The quality of jade is generally graded based on four aspects: color, transparency, texture and clarity. There is no detailed classification of jadeite grades in the national standard, and there are also significant differences in the grading standards among the people. But there are two standards that remain unchanged, namely color and water quality.

First of all, the color should be positive, and secondly, the water quality should be above glutinous (glutinous, glutinous ice, ice, glass).

The identification of finished products is different from that of raw stones. Finished products do not have skins and only need to be analyzed for their color, while raw stones need to be analyzed one by one from the performance of the skin and many aspects. Even if everything is done thoroughly, there is still a high possibility of accidents in the end. Therefore, when purchasing raw stones, we should study the cut and the whole piece of jade material, which can be roughly divided into the following points:

1. Is there greenery? What is the direction and area of ​​greenery?

2. Green concentration and color level

3. Fissures in the epidermis

It should be noted that it is best to pay according to how much green you see. If there is no green, the water quality must be good. If the water quality is good, you need to look at the distribution of cracks. And don't generalize based on a single glimpse. Think from the worst.

1. If a large rough stone has many small openings and each of them has green color, don’t buy it, as it is easy to have “rogue windows”

2. Don’t spend a lot of money on materials with average surface performance

3. Be careful when the broken, cut, rubbed edges of jadeite are green but not polished, as cracks and uneven colors are common.

4. When purchasing jadeite color materials, look for mosses, color mosses and pine flowers on the surface.
