1. The pearl surface lacks hardness, so it needs to be carefully stored. It is forbidden to scratch with a knife or hard objects.
2. Pearl is an organic substance, and its main component is calcium carbonate. Therefore, avoid contact with cosmetics, perfumes and any chemical substances, such as vinegar, orange juice, bleach, sulfuric acid, correction fluid, etc., so as to avoid damage to the pearl surface and loss of luster.
3. After wearing pearls, gently wipe the pearl surface with a soft wet towel to clean substances such as sweat or cosmetics.
4. Don't soak in hot water. Wash pearl ornaments, because it will lead to looseness.
What should I do if the pearl turns yellow?
Although the color of pearls looks good, they can't stand the test for a long time. Generally, after several decades, pearls will turn ordinary yellow and lose their beautiful luster, which is the saying goes.
Why do pearl ornaments turn yellow after long use? This is mainly because the physical properties of aragonite minerals that make up pearls are unstable. Over time, it will become ordinary calcite. Aragonite and calcite have the same chemical composition, but their crystal morphology and luster are different. This is the reason why pearls change color.
There are some remedies after the pearl turns yellow, that is, soaking in dilute hydrochloric acid can dissolve the yellowed shell and make the pearl reappear its glittering and charming color. But if the color becomes very thick, it is difficult to reverse it.
Question 2: What should I use to wash the yellow pearl necklace? How to wash the yellow pearl necklace? Matters needing attention in maintenance.
1. Anti-acid corrosion: In order to prevent the luster and color of pearls from being affected, and avoid pearls from contacting with acids, alkalis and chemicals, do not wear pearl jewelry for swimming or bathing.
2. Stay away from the kitchen: there are tiny pores on the surface of the pearl, which is not suitable for it to inhale dirty substances in the air. Don't always wear beautiful pearls to cook. Steam and lampblack may penetrate into pearls and turn yellow over time.
3. Avoid sun exposure: Because pearls contain a certain amount of water, they should be placed in a cool place, avoiding direct sunlight as much as possible, or in an excessively dry place to avoid dehydration.
4. Anti-scratch of hard objects: pearl jewelry should be stored separately to prevent other jewelry from scratching the pearl skin.
Therefore, I also invited professionals to clean it. I don't want to use online hydrochloric acid to clean myself, because if I don't control the concentration, I will die if I am not careful.
Question 3: Pearl necklaces will turn yellow if they are not kept well. Is there any way to turn white? Some pearl jewelry worn or stored by ancestors for more than ten years may turn dull yellow. For pearls whose yellowing is still limited to the surface layer, they can be soaked in 1%-5% dilute hydrochloric acid or hydrogen peroxide for a period of time. After the yellow shell is dissolved, take out the pearl quickly, wash it with clear water and dry it, and the pearl will regain its luster. However, special attention should be paid not to soak in horrible hydrochloric acid for too long to prevent pearls from being damaged. Of course, if the color becomes very thick, it is difficult to reverse it. For black, dull and heavily dyed pearl jewelry, it can also be soaked in 10% salt water, rinsed with 3% dilute hydrochloric acid solution, and then rinsed with clear water, which can also restore luster.
I hope I can help you!
Question 4: How to clean and maintain the natural pearl necklace? The maintenance of natural pearls mainly pays attention to the following points:
1, don't wear it when taking a bath or swimming, and avoid washing directly with water or acid-base substances such as shower gel and soap. Long-term contact is not good for the luster of pearls.
2. Don't wear it when cooking to avoid long-term contact with lampblack.
3, avoid close to the heat source/fire source, should be stored in a cool place.
4. When not in use, you can wipe the dust and oil stains on the surface with a special flannel. If it is really dirty, don't soak it directly. Instead, you can wipe the surface with a little distilled water on the flannel and dry it before storing it.
I hope I can help you and adopt it. Thank you!
Question 5: The color of pearls is getting darker and darker. What should I use for cleaning? Pearl contains organic calcium carbonate, which has poor chemical stability and can be dissolved in acid and alkali. It is not advisable to touch perfume, oil, salt, alcohol, hair cream, vinegar and dirt in daily life. It is even more impossible to contact organic solvents such as banana oil; In summer, the human body sweats a lot and is not suitable for wearing pearl necklaces. When not in use, gently clean it with high-grade neutral soap or detergent, and then dry it. Exposure or exposure in the sun is not allowed. When collecting, you can't use mothballs, and don't put them in the bank vault for a long time. The hardness of pearls is very low. White pearls will turn yellow and their luster will become worse if worn for a long time. They can be bleached with 1%- 1.5% hydrogen peroxide. Be careful not to bleach excessively, otherwise it will lose its luster. 1, Anti-acid Corrosion In order to keep the luster and color of pearls unaffected, pearls should be prevented from contacting acids, alkalis and chemicals such as perfume, soap and styling water. Don't wear pearl jewelry when swimming or bathing. So please put on your lovely pearls after makeup. 2. There are tiny pores on the surface of pearls far away from the kitchen, which are not suitable for them to inhale dirty substances in the air. Pearl absorbs hair gel, perfume and other substances. So don't wear beautiful pearls to send electricity. Be careful in the kitchen. Don't wear beautiful pearls when cooking. Steam and oil fume may penetrate into pearls and turn them yellow. 3. Put away the cashmere cloth every time you wear pearls (especially in hot weather), so as to keep the luster of pearls. It is best to use sheepskin or delicate flannel instead of paper towels, because the friction of some paper towels will wear pearls. 4. Don't wash the pearl necklace with water until it is close to clear water. Water can enter the pores of beads, which is not only difficult to dry, but also may ferment inside, and the beads may turn green. If you sweat a lot when wearing it, you can wipe it carefully with a soft wet towel and put it back in the jewelry box after drying it naturally. Occasionally, it can be washed with weak alkaline water, which can keep the pearls moist (only wash pearls with nylon strings, not pearls with silk strings). After the pearl turns yellow, it can be soaked in dilute hydrochloric acid to remedy it. Dilute hydrochloric acid can dissolve the yellowed shell, making the pearl show a glittering and charming color again. But if the color turns yellow badly, it is difficult to reverse it. If air is needed, don't put pearls in the safe for a long time, and don't seal them with plastic bags. Pearls need fresh air, so they should be taken out and worn every few months to let them breathe. If pearls tend to turn yellow if they are kept in a box for a long time, that's what I mean. 6. Avoid exposure. Because pearls contain a certain amount of water, they should be placed in a cool place to avoid direct sunlight, or in an excessively dry place to avoid dehydration of pearls.
Question 6: How to restore the color of pearls after they turn yellow? Although the color of pearl is beautiful, it can't stand the test for a long time. Generally, after decades, pearls will turn yellow and lose their beautiful luster, which is what the saying goes.
Why do pearl ornaments turn yellow after long use? This is mainly because the physical properties of aragonite minerals that make up pearls are unstable. Over time, it will become ordinary calcite. Aragonite and calcite have the same chemical composition, but their crystal morphology and luster are different. This is the reason why pearls change color.
There are some remedies after the pearl turns yellow, that is, soaking in dilute hydrochloric acid can dissolve the yellowed shell and make the pearl reappear its glittering and charming color. But if the color becomes very thick, it is difficult to reverse it.
Wear pearl jewelry after makeup, because any beauty products (powder cake, foundation cream, etc. ) is harmful to pearls, including perfume and hair gel. The pearls worn should be soaked in clear water, washed, dried and then hidden, otherwise the pearls will turn yellow easily.
Question 7: What happened to the yellow pearl necklace? How should we deal with it? Pearls are high-grade ornaments, so we should pay attention to daily maintenance. The composition of pearl is calcium carbonate containing organic matter, which has poor chemical stability and can be dissolved in acid and alkali. Therefore, the following points should be noted during maintenance:
1. Do not touch moth balls, detergents, coffee, perfume, oil, salt, alcohol, vinegar and dirt, and do not touch organic solvents such as banana oil, because they will destroy the internal structure of pearls and produce black and yellow beads. If wine or coffee spills on pearls, rinse them with clear water immediately and dry them with a soft cloth.
2. People sweat a lot in summer, so it is not appropriate to wear pearl necklaces. When pearl jewelry is not worn, gently wash it with high-grade neutral soap or detergent and dry it to ensure the lasting brightness of pearl jewelry. Avoid exposure to bright light.
3. When not in use, carefully store it in a jewelry box and keep it moist (don't put it in a plastic bag). It is best not to put it with other jewelry to avoid scratching the pearl surface.
4. The hardness of pearls is very low. White pearls will turn yellow and their luster will become worse if worn for a long time. It can be bleached with 1% ~ 1.5% hydrogen peroxide, but be careful not to bleach too much, otherwise it will lose its luster.
5. In daily wear of pearl jewelry, always check whether the string of jewelry is firm. If it is damaged or falls off, it should be repaired in time to avoid loss.
6. There is a saying in the jewelry circle: Brush jewelry with a toothbrush dipped in toothpaste, and the jewelry that can be used looks as bright as new. It is necessary to clean jewelry, but Yahao is not ideal, because toothpaste contains fine abrasive particles with high hardness, which are very fine but the hardness is as high as six or seven degrees (similar to that of crystal), so cleaning jewelry with toothpaste will damage the surface of gems with hardness lower than that of crystal, especially pearls, gold and K gold; Pearls are absolutely avoided, and the most correct washing solution should be diluted neutral surfactant (such as salad dressing and baby shampoo).
7. Don't touch jewelry often. It seems simple, but it is not easy to wear. Many people can't help touching the surface of a gem when they see its beauty and charm. This will actually affect the luster and brightness of the gem.
From time to time, the human body excretes sweat and oil on the skin surface, and the hand is the most accessible part of the body, so the oil on the skin often pollutes the surface of the hand. When you touch a gem with your hand, the grease on your hand is easy to stay on the gem, which affects the luster and brightness of the gem. In particular, diamonds are lipophilic gems, and their surfaces are easily contaminated with grease, which greatly affects their luster. However, jade white jade belongs to * * * body structure. Frequent touching can make jade more moist and lovely.
8. Tap water will spoil the luster of pearls. Some people want to wash and maintain pearls after wearing them several times. I don't know that cleaning with tap water for a short time has little effect on jewelry, but if it is used to soak pearls, it is absolutely impossible. Because there is a fixed content of chlorine (C 1) in tap water, it will destroy the luster of pearl surface. In fact, mineral water is the best way to soak and wash pearls.
In addition, after wearing pearls, they should be cleaned and maintained before being sent to the safe deposit box in the bank, so as to avoid discoloration of pearls due to dirt accumulation for too long in the future. Moreover, the storage conditions of safe deposit boxes for cash and documents kept by banks are not suitable for tidal gems such as pearls and protein, so they must be taken out every once in a while, soaked in water for maintenance and supplemented with humidity.
Question 8: Teach you how to clean pearl necklaces. Beautiful pearl time 8.5-9m AAA color flawless bright light is round S925 sterling silver freshwater pearl pendant necklace. Some people say that pearl necklaces can be wiped with low-concentration soapy water and lukewarm hot water, or rubbed with proper amount of toothpaste, and then rinsed with clean water. If someone really cleans it like this, I feel heartache for his pearl necklace. You know that pearls are weak in acid and alkali resistance, and so are soap and toothpaste. Soap, from the production point of view, the production of soap is an alkalization process; Toothpaste is alkaline and related to people's own physiology. Human tooth decay is weakly acidic, so toothpaste can be cleaned by alkaline and acid-base neutralization. ) So if you clean like this, can I not feel bad for you? Maybe once or twice, if you still use it as a magic weapon, the result can be imagined; Put it in clean water. In fact, this water is also very particular. If it's tap water, I have to remind you again that you can't directly clean the pearl necklace with tap water, because tap water contains hypochlorous acid, which is a weak acid. It may not affect jewelry for a short time, but if it is used to soak pearls, it will definitely not work. Because there is a fixed content of hypochlorous acid (weak acid) in tap water, when this hypochlorous acid is immersed into the pearl from the opening of the pearl, it will produce a chemical reaction process to produce calcium chloride, which will make the unique halo color of the pearl disappear and become dull. A little hot water may be nothing, I'm not sure, but hot water and boiled water are absolutely forbidden! ! So as to prevent the solution from eroding the pearl epidermis structure. Heart art pearl beautiful time 8.5-9m AAA color flawless bright round S925 sterling silver freshwater pearl pendant necklace How to maintain the pearl necklace? Here I refer to some materials for your reference: in fact, mineral water is the most ideal cleaning and maintenance for pearls that have been worn several times, because it is the easiest to find. But if it's counterfeit money, it's another matter, so sometimes don't be greedy and cheap, spend two yuan more. This pearl is nothing compared with it. (Actually, it can be a neutral solution, such as distilled water, anhydrous alcohol or boiled water (cold). Soak the pearl necklace in mineral water for a period of time. After taking it out, dry it with flannel or napkin and put it in a cool and ventilated place to dry. When there is dirt on the pearl, you can only wipe it with soft flannel or lens paper for glasses or cameras. Some pearls worn or stored by ancestors for decades may turn dark yellow. For pearls whose yellowing is still limited to the surface layer, they can be soaked in 1%-5% dilute hydrochloric acid or hydrogen peroxide for a period of time. After the yellow shell is dissolved, take out the pearl quickly, wash it with clear water and dry it, and the pearl will regain its luster. However, special attention should be paid not to soak in dilute hydrochloric acid for too long to prevent pearls from being damaged. Of course, if the color becomes very thick, it is difficult to reverse it. For black, dull and heavily dyed pearl jewelry, it can also be soaked in 10% salt water, rinsed with 3% dilute hydrochloric acid solution, and then rinsed with clear water, which can also restore luster. Heart art pearl beautiful time 8.5-9m AAA color flawless bright perfect circle S925 sterling silver fresh water pearl pendant necklace Pearl necklace can't stand the erosion of sweat (the composition of sweat varies from person to person, weak acid and weak alkali are possible), so pearls should be maintained regularly at ordinary times.
