How to Identify A-Grade Jade

Three characteristics of natural jadeite

Structural characteristics of jadeite: Natural jadeite has three characteristics that other jades do not have, namely orange peel effect, bean texture, and jadeite texture (fly wings).

1. Orange peel effect

On the surface of jade, there will be bumpy ripples like orange peel, which is a unique phenomenon of jade. Because the crystals are arranged at different angles, their hardness is different. Due to the different hardnesses during polishing, several batches of effects appear.

2. Bean properties

Bean texture refers to the granular feeling on jade jewelry that can be seen with the naked eye. The strength of the bean depends on factors such as how tight its texture is. Jadeite of good quality can only be seen with the help of a magnifying glass.

3. Jadeite

The industry calls the quality of jadeite "fly wings". It is easier to see in the rough jadeite. The jadeite is like small sequins on clothes, which will sparkle under the light.

The other is the three physical and optical elements of jade: the refractive index of light, the density of jade, and the hardness of jade.

The refractive index of jade is 1.66, the density is 3.33, and the hardness is between 6.5 and 7. These physical indicators need to be determined with the help of testing instruments from testing agencies.

If a piece of jade meets the above characteristics, it must be grade A natural jade.
