Avoid contact with chemicals such as sulfuric acid and hydrochloric acid.

Avoid contact with human sweat.

Avoid rain, especially acid rain.

Cleaning method:

If white particles are produced, they can be washed with clean water and dried with a soft cloth.

You can also put the red coral in a plastic bag filled with baby oil, soak it for one night, and dry it with a soft cloth to restore its moist red color.

I. Introduction to Red Coral:

Red Coral: It is an organic gem with pleasant color.

The texture is bright and moist, and it grows in the deep sea from 0/00 to 2000 meters away from human/kloc-. It is listed as one of the three organic gems alongside pearls and amber, and it is also listed as one of the seven treasures in the oriental Buddhist scriptures. It has been regarded as a rich and auspicious thing since ancient times.

Second, the formation of red coral:

Natural red coral is formed by the accumulation of coral polyps, which grow very slowly and cannot be regenerated. However, red corals only grow in several straits (Taiwan Province Strait, Japanese Strait, Baltic Strait and Mediterranean Sea) and are restricted by sea areas, so red corals are extremely precious. Ornaments made of red coral are very popular with collectors, and the value-added of fine red coral is very rapid, which attracts collectors' attention.

Third, in terms of clothing, we should also pay attention to:

Try to avoid contact with cosmetics, perfume, alcohol, salt, oil and vinegar.

Red coral has a small hardness, so it should be packaged and stored separately. When wearing it, be careful not to contact with hard objects, otherwise repeated friction will destroy the smoothness and brightness of the coral surface.

Coral structure is not dense and cracked, so it is not suitable to measure density and refractive index with heavy liquid to avoid pollution.
