Coral, together with pearls and amber, is called three organic gems by westerners and is a very precious gem variety.
China's current national standards for jewelry and jade industry classify natural jewelry and jade into three categories: natural jade, natural gemstone and natural organic gemstone, while coral belongs to natural organic gemstone. The most valuable species of coral is red coral, followed by blue coral.
A good ornament, no matter where it is, should be well protected to prolong its service life and prevent man-made and natural damage.
So how to protect and maintain corals?
1. Coral was bright when it was first bought, but it became dark, dirty and faded after a period of use. In fact, in some cases, the problem itself is not coral, but that it is not well protected when worn.
Coral will turn white after long-term wear, because the human body will sweat a lot in summer, and there are acidic components in the sweat, which will cause chemical reactions.
The best way is to wash coral jewelry with clear water every night after wearing it to wash off the sweat sticking to it to prevent chemical reaction. If it turns white accidentally, you can wash it with clear water, dry it with a soft cloth, and apply baby oil to restore the red color.
Coral ornaments should not be worn for a long time in summer.
2. Coral should not touch cosmetics, perfume, alcohol, salt, oil and vinegar. Coral structure is not dense and has gaps, so it is not suitable to measure density and refractive index with heavy liquid to avoid pollution.
3. Coral has low hardness, so it should be stored separately when it is collected to avoid being scratched by other gems.
When wearing, try not to touch hard things. Repeated rubbing will destroy the smoothness, smoothness and brightness of coral surface.
4. Prevent long-term sun exposure and high-temperature baking, otherwise it will easily lose moisture and luster and even fade.
5. Coral jewelry is dirty, wash it with neutral soapy water or clean water, and then dry it with a clean towel.
6. When maintaining, lightly rub it with colorless waxy baby oil or olive oil, and let it stand for one night to restore luster. In severe cases, it can be gently polished.
