How can pearl necklaces avoid turning black?
To avoid turning black, pearl necklaces can be maintained and paid attention to from the following aspects:
First, avoid chemical erosion
The main component of pearl is calcium carbonate, chemical stability is poor, easy to acid, alkali and other chemical substances erosion. Therefore, in daily wear, pearl necklaces should avoid direct contact with perfume, cosmetics, hair spray, detergent and other chemicals. These substances may damage the luster of the pearl's surface and cause the pearl to turn black or lose its original color.
Second, stay away from dirty environment and high temperature
The surface of the pearl has tiny pores, which are easy to absorb dirty substances in the air, such as soot, dust and so on. Therefore, when wearing a pearl necklace, you should try to avoid entering the kitchen and other heavy smoke environment, and do not spray hair spray or spray perfume when wearing.
At the same time, pearls should not be exposed to a high temperature environment for a long time, such as direct sunlight or heating, so as not to dehydrate pearls and turn yellow or even black.
Third, gentle cleaning and maintenance
Regular and gentle cleaning of a pearl necklace is an important measure to maintain its shine and avoid blackening. When cleaning, you can use a clean wet cloth or soft cashmere cloth to gently wipe the surface of the pearl to remove dust and dirt. Be careful to avoid using chemical cleaners or tap water to clean the pearls directly, so as not to cause damage to the pearls.
After wearing, especially in the case of sweating, the sweat on the surface of the pearl should be wiped with a wet cloth in time to avoid the erosion of the pearl caused by acidic substances in the sweat.
Fourth, proper storage and regular inspection
When the pearl necklace is not worn, it should be properly stored in a soft cloth bag or a special pearl box to avoid scratching or blackening due to friction with other hard objects. Keep the storage environment dry and ventilated, avoid humidity and high temperature.
Regular checks to see if the thread of the pearl necklace is loose or worn are also an important step to avoid turning the pearl black. If there is a problem with the silk thread, it should be replaced in time to avoid the pearl falling off or being unnecessarily damaged.
Fifth, avoid hard objects scratching
When wearing and storing pearl necklaces, care should be taken to avoid rubbing or scraping with hard objects. Pearls are relatively low in hardness and can be easily scratched, resulting in a rough or blackened surface. Therefore, when wearing to avoid contact with sharp objects, storage should also be placed separately to avoid collision with each other.
To sum up, by avoiding chemical erosion, away from dirty environment and high temperature, gentle cleaning and maintenance, proper storage and regular inspection, and avoid hard objects scratching and other measures, can effectively prevent the pearl necklace from turning black and maintain its long-term luster and beauty.
