Pearl, is a vitality of organic gems, with a glossy luster and elegant temperament, like angels shed tears, holy and elegant. Conceived in the water of the pearl, soft outside the firm, the perfect interpretation of women's toughness and soft beauty.
Pearls are often used to celebrate motherly love. Women are full of vitality when they are young, their skin is blown and elastic, but as time goes on, wrinkles creep up on their faces. Life ages, and so do pearls. Therefore, in order to let the beautiful pearls stay young and bright, we need to carefully maintain and care.
01 What causes pearl aging?
The so-called old pearl, the pearl aging means it turns yellow? The answer is not so, pearl aging does not turn yellow, but the color becomes lighter, the luster becomes worse. So what causes pearls to age?
The luster and color of the pearl are the external expression of the nacre structure and component elements, and the largest component of the nacre is calcium carbonate, and the shape of calcium carbonate is also different because of the different structure. The calcium carbonate in the pearl initially exists in the form of aragonite, but the physical properties of aragonite are not stable, and over time, it will become ordinary calcite.
The shape of calcium carbonate crystals of aragonite and calcite is completely different, and the columnar crystal structure is broken into other shapes, and this microscopic and slow change process is the process of pearl aging slowly. Because arachite and calcite are white when they do not contain impurities, but the luster is very different, so the process of pearl aging is the process from arachite to calcite.
02 What really causes pearls to turn yellow?
The pearl turns yellow because it is stained with sweat when it is worn, mainly caused by improper maintenance, just like excessive sweating in summer, the white T-shirt will yellow for a long time, the pearl will also yellow because of sweat. Mainly because sweat contains urea, uric acid and other substances, they penetrate the surface of the pearl. When a pearl absorbs light other than yellow for a long time, when natural light hits the pearl, we will see the pearl take on a yellow color.
In addition, pearls that are not used for a long time are easy to lose moisture and become yellow after about 60, 70 or 100 years. A pearl has about a hundred years of opportunity to show its brilliance, so it is entirely possible to complete the inheritance of three generations of good quality pearls. Pearls are not as eternal as plastic flowers, but they have experienced and witnessed the changes of a long time, making people feel its feelings and charm.
In 2019, foreign archaeologists found natural pearls dating back more than 8,000 years on Marawa Island near ABU Dhabi, and although the pearls have dimmer, they can still imagine the beauty they once had from the residual luster. The pearl has been on display in the UAE for the first time in its 8,000 years of history.
03 How to make the yellow pearl return to the natural color?
It has been suggested that dilute hydrochloric acid can make pearls white again. In fact, the reaction of hydrochloric acid and calcium carbonate causes the pearl structure to react with the yellowing surface, revealing a fresh white layer of beads, so that the pearl's luster naturally becomes worse. If you want to make the pearl restore the real beauty, it is more suitable to soak in medical hydrogen peroxide bleaching, while dropping a drop of detergent. The bleaching effect is gentler and won't hurt the pearls. With proper care, pearls can also have a relatively long life.
04 How should pearls be maintained?
Therefore, if you want to make your pearl "Tong Yan" not old, you can't live without her maintenance. So how should pearls be maintained?
1. Avoid water
The water contains a fixed amount of chlorine (C1), which will damage the luster of the pearl surface. At the same time, the pearl has water absorption, if washed with water or contact with sweat, the liquid will enter the precious hole, resulting in chemical changes, so that the unique luster of the pearl disappears, and may lead to the phenomenon of the pearl cracking.
2. Acid and alkali erosion prevention
The composition of the pearl is calcium carbonate, such as pearl contact with acids, alkalis and chemicals, chemical reactions will occur, thereby destroying the luster and color of the pearl. Such as juice, perfume, hair spray, nail polish remover, etc. Therefore, please wear pearls after makeup, and do not wear them during hair perming and dyeing.
3. Avoid the sun
As pearls contain some moisture, they should be kept in a cool place. Such as long-term exposure to heat or ultraviolet radiation, or lead to pearl dehydration.
4. You need air
Pearls are living organic gems, so do not seal them in jewelry boxes for a long time, and do not use plastic bags to seal them. Being kept closed for a long time is easy to cause the pearl to dry and yellow, so it should be worn every few months to let the pearl breathe fresh air.
5. Cloth cleaning
Every time after wearing the pearl jewelry (especially when wearing sweat), you only need to use a fine velvet cloth to wipe the pearl clean. If you encounter stains that are difficult to wipe, you can dip a flannelette into a little distilled water to wipe the surface, and then put it back into the jewelry box after natural drying. Do not use face paper to wipe, rough face paper wipe will wear the pearl skin.
6. Keep away from oily fumes
Pearl is different from crystal and other ore jewelry, it has small pores on the surface, so it is not appropriate to let it inhale dirty substances in the air. If you wear pearls to cook, steam and smoke will penetrate into the pearls and make them yellow.
7. Store separately
Pearls are more elastic than other gemstones, but their chemical composition is calcium carbonate, less hard than dust in the air, and easy to wear. Therefore, pearl jewelry needs to be stored separately to avoid other jewelry items scratching the pearl skin. If you are going to wear a pearl necklace on your clothes, the texture of the clothes is best to be soft and slippery, too rough fabric may scratch valuable pearls.
8. Get regular checkups
Pearl thread is easy to loose over time, so it needs to be checked regularly. If it is found loose, replace the silk wire in time. Pearl silk is recommended to be replaced once every 1-2 years, depending on the number of times worn.
Precious things, must need careful maintenance of the owner, in order to endure. Pay attention to the maintenance method of pearl jewelry, in order to make the beloved pearl forever Guanghua, the years are not old.
