It's true. The growth line is still on it. In fact, you can make a slight stroke with a knife and the fine pearl powder will come down, but the pearl is still very smooth. The pearls you bought are 100% genuine.
In ancient times, pearls were regarded as a symbol of power and wealth because of their elegant and holy character and confusing life experience. Chinese and foreign emperors' robes, robes and armor are all symbols of the supreme power of the country.
In history, many countries have made laws to make pearls a patent for members of the royal family. The rulers also launched bloody wars again and again for pearl resources. As early as 3700 years ago in Shang Dynasty, pearls and tortoise shells were tributes. The minister of the king of the Tang Dynasty once suggested making a "four-party offering order": "Due to the south, please make the pearl tortoise shell as an offering."
Religious circles use pearls to arouse people's loyalty to their beliefs. The "seven treasures" in Buddhism, including pearls, are embedded in Buddhist sacred objects and are worshipped by believers. The crown of the Queen of the British Empire is inlaid with 227 pearls, one of which comes from a butterfly shell with a diameter of 1.8 cm. It is said that British colonists plundered the South China Sea that year. The crown of Russian Queen Catherine II is inlaid with 80 priceless pearls.
According to the literature, Cixi wore a golden crown with an egg-sized Nanyang dragon and phoenix pearl inlaid on it. Unfortunately, this pearl was taken away by warlord Sun Dianying. It is said that it is for Song Meiling. Qianlong Zhu Chao is also made of 108 pearls.
Pearl culture technology has been very mature. The average pearl necklace is also very cheap between 50 and 200 yuan, which is very suitable for middle-aged and elderly women to wear.

It can be identified by color, hardness, shape, taste, specific gravity, luster, texture, holes, fluorescence and properties.

Is it necessary to buy expensive pearls?
If you want to buy high-quality pearls, buy expensive ones.
Pearl is one of the most famous jewels in the world. Almost everyone can recognize pearl ornaments at a glance among many jewels, but there are different opinions about the price of pearls. In modern times, the price of pearls is largely determined by their varieties. Just like conch pearls today, wild pearls in the past are precious because they can't be cultivated artificially. Among the varieties that can be cultured artificially, seawater pearls are generally more expensive than freshwater pearls, followed by Nanyang White Pearl, Nanyang Golden Pearl, Tahiti, AKOYA, Jinduoma and freshwater pearls. Of course, sometimes large and high-quality freshwater beads are not cheaper than AKOYA, and the final pricing standard still depends on their true value.
How to choose pearls:
1, pearls have different shapes, with natural iridescent pearlescent and metallic luster reflection, so the luster of each pearl is different. The artificial beads are uniform in shape and the pearls are dull.
2. Pearls feel astringent after rubbing against each other, but they still feel astringent when rubbing against glass. False beads have a smooth feeling after rubbing against each other, and false beads also have a smooth feeling after rubbing against glass.
When the pearl touches the skin, it feels cool. Breathe into the pearl with your mouth, and the surface will fog. False beads feel smooth and warm when they touch the skin.
When a pearl is burned with a small fire, its appearance will turn black, but when it is rubbed, its luster will remain the same. It will crackle when it is burned with a big fire. Natural pearls have a stronger cracking sound than cultured pearls. The lobes are numerous tiny arc-shaped fragments, silvery gray with colorful luster, and the periphery is translucent. The artificial beads are uniform in shape, will burn in case of fire, have a plastic taste, and the ashes are flat or broken, and the color is black and dull.
5. Put the pearl in banana water for a few minutes, shaking and shining. The fake was shaken in banana water for a few minutes, and the surface gloss was completely lost. The remaining beads are milky white, milky yellow or pure white, translucent and dull, some have fine parallel textures, and some have small pits or round holes.
How many years can pearls be worn before they become useless?
Pearls were worn out in 100 years. Pearl is a kind of calcium carbonate crystal combined with special colloid of shellfish, which contains more than 90% calcium carbonate and about 4% water, which can make pearl dazzling. The life span of the pearl itself is 250 years. If pearls made into jewelry are worn for 100 years, they are almost useless. Usually wearing pearl jewelry for too short a time and not maintaining it well will only shorten the life of pearls. After about 50-60 years, pearls will slowly lose their luster and begin to turn yellow. This is because when pearls are made into jewelry, they will go through various processing techniques, which will destroy the internal structure of pearls to a certain extent, and will get all kinds of grease and sweat when they are worn for a long time. If not cleaned in time, pearls will be corroded more easily and their service life will be shortened. When storing pearl necklaces, do not seal them with sealed bags. Because pearls need to breathe fresh air, if they are kept in a sealed environment for a long time, they will easily turn yellow, thus affecting the service life of pearl necklaces. Therefore, it is recommended to store pearl necklaces in a cool place to avoid dehydration of pearls.
Is the pearl necklace with tens of dollars true?
Maybe it's true, maybe it's just nucleated pearls, and the price of ordinary freshwater pearls is actually very low.
