Most of the natural jadeites of A goods are bright and colorful, which go deep into the bone marrow and wood, as shown in figure 1.

Goods B are artificially colored, floating and blurred, and distributed along the cracks, as shown in Figure 2.

Second, according to the texture:

Most jadeites that have been artificially treated are dull in texture, and jadeites of the same size are lighter in weight. However, the texture of natural jade is glassy, bright and heavy.

Third, identify by the head:

Due to chemical treatment, the water head, that is, transparency, will be affected. Even with glue treatment, most of the water heads are very low or even dry. The natural jade looks clearer and more transparent.

Precautions for jade preservation:

1, don't collide with hard objects. Jade is easy to crack after collision. Sometimes, although the cracks are invisible to naked eyes, the molecular structure in the surface layer of jade has been destroyed, resulting in dark cracks, which will be exposed over time, greatly damaging its perfection and collection value.

2. Avoid dust and oil pollution as much as possible. If there is dust on the jade surface, clean it with a soft brush; If dirt or oil stains are attached to the jade surface, it can be scrubbed with mild soapy water and then washed with clear water.

3. Jade pendants should be put away when not in use. It is best to put them in jewelry bags or jewelry boxes to avoid collision.

4. Avoid contact with perfume, chemicals, soap or human sweat. Because jade is exposed to too much sweat, it will be eroded, destroy the outer layer and affect the original bright chromaticity. Especially white jade-suet white jade is more resistant to sweat and grease, so it should be wiped with a weak cloth after wearing.

5. Don't place the sun in direct sunlight for a long time. Jade will expand in the sun, and its molecular volume will increase, which will affect the quality of jade, so it is more taboo to be close to the heat source.

6. Tea can raise jade, and the way to raise jade is similar to raising tea pets. For example, the jade raised by green tea is smooth, the jade raised by black tea is red, the jade raised by Fu tea has beneficial probiotics, and the jade raised is not fragile.
