Do pearls have a shelf life? Do pearls retain their value and how long can they be stored

As the saying goes, "people old pearl yellow" is not valuable, and the color of the pearl turns yellow, which means that it has aged.

Pearls are a type of organic gemstone, but their chemical composition is mainly calcium carbonate.

caCO3), which also contains trace amounts of amino acids.

It is precisely because the main chemical component is calcium carbonate that pearls have poor acid resistance. If there are acidic components in the air, its surface will gradually lose its original luster, accelerating its aging. It is entirely possible to keep the pearls for more than ten years.

When wearing pearl jewelry in summer, it often comes into contact with sweat (acidic substance), and should be rinsed in clean water (without adding any cleaning agent) after wearing it for about a week to remove sweat. After cleaning, the pearl jewelry should be hung in a ventilated place to dry and set aside, and must not be exposed to the sun!

When the pearl jewelry is not worn, it should also be wrapped in a soft cloth and stored separately, and do not come into direct contact with other gemstones (the Mohs hardness of pearls is only about 3, and other gemstones are hard, which will shave the surface of the pearl). It should also be handled with care, and should not touch or rub with hard objects.

Only by paying careful attention to maintenance, the life of pearl jewelry will be extended.

Yes, pearls are easy to oxidize after a long time, lose their original luster, and long-term storage will also make pearls oxidize into powder!

It can maintain its value, and there is no problem in keeping it for decades under normal circumstances.

Pearls have saltwater pearls and freshwater pearls, its color, roundness, luster, diameter and other aspects affect its value, pearl beads are large, round, uniform color, luster is as good as possible; In general, saltwater pearls are more valuable than freshwater pearls, especially varieties such as South Sea gold pearls and Tahitian black pearls.

Pearls are organic gemstones, the main ingredient is calcium carbonate, unlike diamond gold jewelry that can be preserved forever; The length of time it is stored depends on the environment in which it is stored, and if it is not properly stored, the pearl will lose its moisture and will lose its luster, and then its value will be reduced.

Under normal wear, pearls can be kept for decades without any problem; Its value is determined by its size, luster, shape, imperfections, etc.

Care of pearls:

1. Anti-acid erosion:

In order to keep the luster and color of pearls unaffected, avoid exposing pearls to acids, alkalis and chemicals, such as perfumes, soaps, styling waters, etc. Do not swim or bathe with pearl jewelry. So please put on your lovely pearls after applying makeup.

2. Stay away from the kitchen:

There are tiny pores on the surface of pearls, so it should not be allowed to inhale dirty substances in the air. Pearls absorb substances such as hairspray, perfume, etc. So don't wear beautiful pearls to the electric hair, and be careful in the kitchen.

Don't wear beautiful pearls to cook, as steam and fumes can seep into the pearl and turn it yellow.

3. Cashmere cloth waiting:

Every time you wear a pearl (especially on a hot day), you must wipe it clean before putting it away to maintain the pearl's luster. It is best to use sheepskin or fine flannel rather than tissue paper, as the friction of some tissue paper will wear the pearls.

4. Not close to clear water:

Do not clean the pearl necklace with water. Water can enter the small holes of the beads, which is not only difficult to dry, but may also cause the inside to ferment, and the bead threads may turn green. If you sweat a lot when wearing it, you can use a soft wet towel to carefully wipe it off, dry it naturally and put it back in the jewelry box.

After the pearl turns yellow, it can be remedied in this way: soaking it in dilute hydrochloric acid can dissolve the yellowed shell, so that the pearl can regain its brilliant and charming color. But if the color turns so yellow, it is difficult to reverse.

5. Need air:

Do not keep pearls in a safe for long periods of time, and do not seal them with plastic bags. The pearls need fresh air, so they need to be taken out and worn every few months to let them breathe. If the pearl is placed in the box for a long time, it is easy to turn yellow ("people old pearl yellow", which is what it means. ）

6. Avoid sun exposure

Since pearls contain a certain amount of moisture, they should be kept in a cool place, try to avoid direct sunlight, or in a place that is too dry to avoid dehydration.

7. Anti-hard object scraping:

Keep your pearl jewelry separate so that it doesn't scratch the nacre from other jewelry. If you're going to wear a bead chain on top of your clothes, it's best to have a soft texture. Too coarse material may scratch your precious pearls.

It can maintain its value, and there is no problem in keeping it for decades under normal circumstances.

Throughout the domestic jewelry market in the past 20 years, the mainstream jewelry materials consumed have experienced the flow of **, platinum, diamonds, and jadeite, and in recent years, colored gemstones and pearls have become popular categories in many jewelry. The domestic jewelry consumption is also gradually shifting from investment consumption to emotional consumption and beauty consumption.

After enumerating the characteristics of various types of jewelry, Ruan Tiejun said that pearls are the only varieties that best represent Chinese culture among the several categories of important gemstones recognized in the world. Pearls have a warm, dignified, and long-lasting "beauty", and the wives and queens of heads of state wear pearls as official standard jewelry on many solemn occasions.

When talking about the current consumption of jewelry, Ruan Tiejun said that at present, Chinese society as a whole is still a follower of European and American fashions: many Chinese people are superstitious about foreign goods, and even discriminate against national brands. Although international luxury brands have entered the market in a big way, China's outstanding national enterprises have long been prepared to accumulate strength by improving quality, expanding channels, and cultivating markets.

Jewelry is beautiful and timeless, not easy to wear and not easy to deteriorate, so it can retain its value. There is also a condition to be satisfied with value preservation: the purchase channel is reliable, and there is not too much premium eaten up in the intermediate link.

Pearls are not particularly recommended for investment value in all kinds of jewelry. The value of a string of beads varies greatly in the eyes of different people, and there is no relative standard valuation. Due to their instability, pearls do not serve as heirlooms like other gemstones.

Expansion: How to care for pearls:

Pearls need to be worn often, and sometimes, we are reluctant to use more precious things because we are afraid of scratching. But what I want to say is that pearls must not be left there, they will easily darken their luster, so there are many ways to wear them often. In addition, after each wear, you must remember to clean it slightly, gently wipe it with a soft cloth dipped in water, and then dry it and put it in the jewelry box.

Be sure to place them separately and do not put the pearl with something sharp to avoid scratching the surface of the pearl.

Difference Between Pearls and Shell Beads:

Where is it. Shape and size.

Because natural pearls are round or irregular in different degrees, the size, color, and shape of the pearls in a necklace are rarely exactly the same, and each pearl will have slight deviations. Because they are artificially made, shell beads are easier to shape than natural pearls.

color and shine.

The color of the pearl is generally the top color of imitation pearls, such as pure white, malachite green, dark gold, etc., and the color is very gorgeous. In addition, the color of the shell beads is floating on the surface, so the color of the shell beads will be unnatural and dull.

Density. Because the density of shell beads is smaller than that of pearls, shell beads of the same size weigh much less than pearls. And this weight difference is very obvious, you can feel the difference when you touch it with your hands.

Surface features. The beads are artificially made, so there are fewer flaws in the appearance. And the natural treasure will be more or less a little flawed.

In order to correctly distinguish between pearls and shell pearls, we must also know pearls very well. Therefore, although the WeChat mini-program Jinyu World tells everyone how to distinguish between pearls and shell beads, it is still necessary to be cautious when actually purchasing.

Can pearls retain their value, my easy-to-clean pearls can't retain their value, I think**he is the one who can retain their value.

As a precious jewelry, Zhengzhou's value preservation is still relatively high, and if it is stored in a cool and dry place and properly preserved, the storage time is relatively long, so it is usually necessary to study carefully for the maintenance of different jewelry and clean storage, and the standardized operation will be better.

Pearls also depend on the quality, and in general, pearls do not have much value retention.

Ways to preserve pearls:

If you want to prolong the preservation time of pearls, you need to pay attention not to clean the pearls with water, otherwise the water vapor will enter the stomata of the pearl and ferment inside, and the pearl line may turn green, which will have a certain impact on the quality of the pearl. If you wear pearls and get stained with sweat or rain, you should dry them with a towel in time.

When preserving pearls, it is also necessary to keep the pearls away from the kitchen, because there are many tiny pores on the surface of the pearls, and the kitchen will float out a large amount of smoke, dust and other dirty substances, which will cause the pearls to appear yellow after entering from the pores on the surface of the pearls. <>
