Jade says "cotton", do you know it?

Pure natural jade must have cotton. Although the cotton and lines of some top-quality glass-type jade cannot be seen with the naked eye, the cotton can still be seen under a microscope. That is the unique structure of natural jade. If there is no cotton, it is not natural jade. It’s just that some jade cannot be seen with the naked eye.

The cotton in jade is a translucent white mineral impurity distributed inside the jade, which appears in patches, filaments and waves, similar to cotton wool. The cotton wool in jade appears white to the naked eye and is also called white cotton. Cotton wool is a type of jade defect that makes the jade base messy and affects the overall beauty of jade. Large cotton wool will appear as obvious white inclusions; fine cotton wool will appear like a layer of mist inside the jade.

The white cotton in jade is the result of the disordered arrangement of crystals inside jade. It may also be cotton wool formed when impurities enter the jade during the jade formation process. Most of them are dot-shaped cotton, which is white cotton. "Cotton" as a type of jade defect will not only directly affect the light transmittance and water head of jade, but also affect the value of jade. However, "no cotton, no jade" does not mean that all jade with cotton are worthless defective products. There is a kind of cotton that not only does not affect the beauty of jade, but also enhances the artistic and collection value of jade. This kind of cotton is snowflake.

The formation process of snowflake cotton is extremely difficult. It can only be formed under a stable environment of low temperature and high pressure. Therefore, the output of jade with snowflake cotton is very scarce. Snowflake cotton must be combined with excellent water quality to show the beauty of snowflake dots and light grains like frost and snow, making the tranquil base like water, adding a poetic and picturesque artistic conception, thereby enhancing the artistry and market value of jade.
