How to distinguish jadeite from water foam?

There are several obvious differences between jadeite and water bubble: the structure of jadeite is far more delicate than that of water bubble; the color of jadeite is richer; the rigidity and glossiness of jadeite are stronger; the refractive index, specific gravity and hardness of jadeite are all higher than those of water bubble. Therefore, we distinguish and identify jadeite and water foam based on these aspects.

The first method: weighing and scoring

Because the density of jadeite is higher than that of water jade, there is a big difference in weight between the two. When you hold jade in your hand, you feel a distinct pressure, while jade feels light and airy. At the same time, the hardness of jade is much higher than that of water foam, so this characteristic can be used to identify it by scratching. It is easy to scratch jadeite with quartz or crystal, but it is difficult to scratch jadeite.

Second: Observe with your eyes

This identification method makes use of the fact that jadeite has a higher refractive index than jadeite. To the naked eye, jadeite appears to have a glassy luster and is quite dazzling; whereas the reflected light from water foam is relatively weak, has no glassy luster, and the light is also relatively soft. One thing must be noted here: if jadeite of poor quality is compared with jadeite of very high quality, this identification method may not be accurate.

The third method: tapping

This knocking method is mainly used to distinguish and identify finished jadeite products and water foam products. When knocked, the sound of jade is very crisp, while the sound of water bubble is relatively dull.

Fourth: Look at the appraisal certificate

The most direct and accurate way is to go to a formal appraisal agency to issue an appraisal certificate.

No identification method can be 100% accurate in making a distinction. Counterfeiters are also well aware of these identification methods, so they will use special means to make up for these aspects. For example: In order to make the weight of the Shuimozi raw stone close to that of the jadeite raw stone, some counterfeit vendors often fill the inside of the Shuimozi raw stone with lead to increase the specific gravity. Some of them have yellow bands and are used to impersonate yellow jadeite. There are also water bubbles that contain many small bubbles, which look very similar to the cotton spots of snowflake cotton, and are used to impersonate snowflake cotton jade.
