Seven, red coral necklaces, bracelets and pendant chains are the best holy products to promote blood circulation and health care.

Coral maintenance: Because the chemical composition of coral is CaCO3, its chemical properties are unstable. People should not wear coral necklaces for a long time when sweating in hot summer, because the salt and acid secretions in sweat will corrode corals. Coral should not touch cosmetics, perfume, alcohol, salt, oil and vinegar. Coral structure is not dense, porous and easy to get dirty. Use neutral soapy water when cleaning.

Cleaning method: Rinse the coral with clear water after use, and then dry it with a clean cotton towel. Maintenance method: put it in colorless waxy baby oil or olive oil for at least one night to restore luster.

Because the chemical composition of coral is calcium carbonate, its chemical properties are unstable, and the surface of red coral will turn white after long-term wear and tear. This is because the human body will sweat a lot in summer, and there are acidic components in the sweat. When calcium carbonate meets acidic medium, it will produce chemical reaction and produce white calcium oxide. Calcium oxide has no effect on white coral, but it has great effect on red coral. If the coral is not cleaned after wearing, the sweat will react with the red coral to generate white calcium oxide, which will grow firmly on the red coral, even if it is washed by an ultrasonic cleaner. The best way is to wash the red coral jewelry with clear water every night, and wash off the sweat sticking to it to prevent it from chemical reaction, so that white calcium oxide will not appear. If white calcium oxide particles have been produced, they can be washed with clear water, dried with a soft cloth and coated with baby oil to restore red. This is just a remedial measure. Coral ornaments should not be worn for a long time in summer.
