This is a well-known thing, and there is nothing to say. By the way, when jade is not worn, it's best to put it in a suede cloth bag, and it's best to wrap several layers of cloth outside, so as to avoid the damage caused by accidental falling when taking it out.

2. Avoid excessive temperature difference.

This is something that many people don't realize. For example, jade exposed to the sun in summer should not directly enter the air-conditioned room, and jade frozen outdoors in winter should not directly enter the heating room. It sounds troublesome, but it's actually very simple. When you go out in winter and summer, let the jade wear it, and the temperature difference will not be too big.

Step 3 keep jade clean

Gemstones need to be kept clean and the dust on the surface should be brushed off in time.

When cleaning jade, you can use clean water. If the climate is cold, you can use warm water of about 30 degrees. Some people will boil jade in hot water first, and then apply maintenance liquid, which is very wrong. Soak in normal temperature water or warm water, and brush with a toothbrush. If the jade is dirty, you can scrape it off with neutral soap, stir it in warm water, and then clean it.

Generally speaking, the soap we use belongs to neutral soap. Although it is not neutral in the true sense (slightly alkaline), it is completely ok to use it on jade.

4, choose the right maintenance supplies

As mentioned above, don't think that sweat, leather oil and messy vegetable oil can maintain jade. Jewelry and jade conservation is a very professional field and an important category of daily chemical industry. This determines that it is best to choose professional products such as colorful to maintain jadeite.

5, frequent contact with water

Jade cracks, in addition to the temperature difference is too large, it may also be because it is too dry. Therefore, it is necessary to expose jade to moisture regularly. Except lapis lazuli and a few other stones with loose structure and bright colors, almost all jade is suitable for blisters. Jade can be soaked in clean water at room temperature for two hours at regular intervals (such as 1 month).

Extended data:

The proportion of impurity minerals is very small, generally occurring individually, and the total amount does not exceed 1%. The appearance also has certain regularity: there are apatite, magnetite and a small amount of eaves in white jade, the average particle size of apatite is about 0.025 mm, and magnetite is about 0.0 1 mm, and the size of cabinet stones is quite different. The typical hexagonal columnar cross-sectional shape of apatite can be seen under the microscope, which shows that the degree of automorphism is good.

Magnetite is authigenic or semi-authigenic Tung stone is brownish yellow, weakly polychromatic and has poor morphology under single polarization. Under orthogonal polarization, the color of banded minerals is disturbed, and the content is generally a few grains. Besides apatite and magnetite, the impurity minerals in sapphire also contain plagioclase, zoisite and trace graphite. The impurity minerals in sapphire are mainly the same as those in white jade, and sometimes there are mineral impurities in sapphire.
