The best one is purple, then pink, but both of them have low output and good luster, so it is difficult to wear a necklace in the same year, but they can still be seen in Hong Kong. The output of black pearls is also very low, and they are rarely used in necklaces.
Then it is milky yellow, white and gray, and white is the most common. Of course, it depends on how to distinguish these. Natural luster and transparency are good, and the size is irregular. If most of them are well proportioned, it is possible to synthesize pearl powder.
Artificial and synthetic depend on the resolution.
Finally, synthetic coloring is basically worthless.
Question 2: Which color pearls are more expensive? Black pearl is the crystallization of the most difficult years, so it is rare to be noble after suffering.
Black pearls are the most painful tears of mother-shells, and the mysterious luster flowing has never made people easily peek into their hearts.
Black pearl is the most elegant spirit in the sea, printed with deep sea color, which seems to be rough, but it can't see through its reserved and steady appearance.
Legend has it that when a drop of dew falls into the sea, if it happens to be caught by an open shell, it can form a crystal pearl. If the weather is bad, the dew under the gray sky will fall into Heiberg and form a black pearl.
This legend has been handed down from15th century, which makes people feel that black pearls are tears when the sky is sad, so the color is deep and dignified, unlike ordinary white pearls.
Another legend is more beautiful. Oro, the god of peace and fertility, came to earth in a rainbow and dedicated the black-lipped pearl Bettie to mankind. TeUfi is the mother shell that produces black pearls.
In a word, that mysterious and noble black pearl comes from the gods and is a treasure between heaven and earth.
At present, there are only two natural producing areas of black pearls: one is Tahiti, Polynesia, which produces 95% of the world's black pearls; Followed by Penglin Island and Majushiki Island in Cook Islands, accounting for 4% of the total output. The output of other Pacific islands is less than 1%. These two areas live together in the south-central Pacific Ocean, so they are also called black pearls as black Nanyang pearls.
Fritillaria, which produces black pearls, is a kind of black butterfly shell that secretes black nacre. The beauty of black pearl lies in its natural black tone and various colorful colors, among which the most appreciated are malachite green, deep purple, navy and other rainbow colors. Its strong metallic luster will change with the rotation of the pearl, which is incomparable to other color-changing pearls.
The annual output of high-quality black pearls is estimated to be no more than 6.5438+0.5 million, of which 40% is sold through international auction every year. The particle size of most black pearls is between 9mm- 10mm, and about 60% black pearls are less than 1 1 mm, so it is generally considered that 1 1mm is the boundary of black pearls, while round black pearls above 15mm are very rare.
In ancient China, black pearls represented wisdom. It is guarded between the dragon's teeth and exudes attractive luster. However, whoever wants it must first conquer the dragon. The size and strength of dragons are daunting, so those who can conquer dragons must have extraordinary wisdom to be worthy of black pearls.
Selected black pearls
Black pearls can generally be divided into the following three types:
1. Natural black pearl
Black pearl cultured by nuclear implantation (cultured in Hyriopsis cumingii, maybe in some kind of mother-of-pearl). This mother-shell lives in the coral reef waters of French Polynesia.
2. Rare brown to black seedless cultured pearls.
There are more and more colored pearls, including dyed black pearls, radiated pearls and the latest so-called "laser-treated" pearls.
3. Imitation pearls made of black shells.
Some rare imitations are coated with a layer of black essence de orient film on the surface of the ball core, or made into beads with black shells to polish the pearl luster.
Distinguish natural black pearls from cultured black pearls, colored black pearls and imitations. Careful observation of the luster of the coated pearls shows that the pearlescence of the coated pearls comes from the bottom of the polymer thin layer, while that of the untreated pearls comes from the top layer of the pearls. The abnormal reflection of the color on the top surface of the pearl can also be observed, which is also helpful for the detection of this kind of pearl. The color of this pearl is pink from the top and blue from the side; The black pearls treated in this way have purplish tops and green sides.
The characteristics of high-quality pure black pearls include:
1 Pearl surface is particularly smooth.
Pearls have a sticky feeling to the touch
3. The edge of nacre laminate is hard to see, and a sharp tool and a concave colorless cover can be seen.
This can be said to be the law of the market: as long as a commodity has a good market, it will inevitably be copied. Black pearls are no exception. It is not difficult for us to see so-called black pearls in jewelers, but some businessmen forget to put the word "dye" in front of black. When you ask whether these black pearls are real, profiteers can brazenly answer: they are really cultured pearls. Yes, they are dyed with real seawater or freshwater cultured pearls ...
Question 3: What color pearls are more expensive? The colors of pearls can be divided into five major colors: white, black, gold, pink and purple.

First, from the appearance of pearls, each pearl is different in size and shape;
Second, look at the luster of pearls. Real pearls glow softly in the light, while artificial pearls have no luster.
Third, when two pearls rub against each other, pearl powder will appear on the surface, but if the powder is wiped off by hand, the surface of the beads will be as bright as ever.
There are two kinds of pearls from the source: seawater pearls and freshwater pearls. There is a kind of seawater pearl in China, which is the pearl produced by Pinctada in Guangxi and Hainan, and is called "Nanzhu". Freshwater pearls are mainly produced in the middle and lower reaches of the Yangtze River, and are produced by Hyriopsis cumingii or Cremantria plicata.
In the Pharmacopoeia, seawater pearls and freshwater pearls are equally wonderful. In the instruction manual of Japanese cosmetics raw materials, there is no distinction between the sources of pearls. Why?
A variety of analyses have found that there is no fundamental difference in composition between freshwater pearls and seawater pearls. Three kinds of amino acids in freshwater pearls are lower than those in seawater, and two kinds are the same. The remaining 13 amino acids are even higher than those in seawater pearls (for example, Weng Fulin of China Pharmaceutical Journal No.5, 1989, 3 13 Hospital, etc.). The analysis results show that the chemical composition of freshwater pearls and seawater pearls is basically the same, and more studies have proved this.
Now freshwater pearls and seawater pearls have been cultivated artificially. Freshwater pearls adopt seedless culture technology.
Seawater pearls adopt nucleated culture technology, so they have a nucleus made of shells or bones; Freshwater pearls adopt seedless culture technology, so the composition is 100% pure pearls.
The nacre thickness of seawater pearls is only 0.3~0.8 mm, while freshwater pearls 100% are nacre. If you want to make 100% pure seawater pearl powder, you must remove the core, and the price is amazing.
So the difference is the cost, and everything else is basically the same.

Four precious pearls: 1. Akoya pearl
Akoya pearl is a kind of seawater pearl cultivated by oysters. Although Akoya is called Japanese Akoya Pearl, its oysters originated in China, and China has a long history of cultivating seawater pearls with oysters in southern China.

If you want to choose a better gift, you can choose Okaya to cultivate pearl jewelry artificially. Second, natural freshwater pearls.
Most freshwater pearls come from China, accounting for 80% of the world's output. China (International) Pearl Festival is held in China every year. The mother-of-pearl of freshwater pearl is Pinctada martensii hybrid or mussel, and the roundness and luster of freshwater pearl are the main factors affecting its price. Freshwater pearls are natural pearls molded in oysters or mussels, or pearls cultured in oysters or mussels in rivers, lakes or ponds. Freshwater pearls are often richer in shape and color than seawater pearls. Just because the price of freshwater pearls is lower than that of seawater pearls does not mean that the quality of freshwater pearls is not as good as that of seawater pearls. In fact, some high-quality freshwater pearls are very precious.
Third, Nanyang Pearl
South China Sea Pearl, referred to as Nanyang Pearl for short, is produced in the South Pacific Ocean and widely distributed in the Indian Ocean and the Pacific Ocean, including northern Australia, Indonesia and the Philippines. Because Australia is rich in products, it is generally called the Pearl of South Asia in Australia. The mother shell of Nanyang Pearl is a white butterfly, which is the largest. The color of Nanyang pearls ranges from white to golden yellow. Its size is usually greater than 9mm, its diameter is generally 10- 15MM, and some of them will reach 19 mm.

It has a charming white tone, almost approaching silver. These pearls are much larger than ordinary pearls, with excellent smoothness and roundness. Nanyang pearl is also the rarest and most special pearl in jewelry.
Fourth, Tahiti black pearl.
The luster of Tahiti pearls is like the feeling of metal, and the thickness of pearl layer should be at least1mm. Any Tahiti black pearl with a nacre thickness less than 1mm cannot be called Tahiti pearl. Tahiti pearls are very precious and can be seen at the auction every year. Not all Tahiti pearls are black. In fact, its colors are far richer than you think, such as gray, green, blue, lavender, brown, black, and rainbow colors like peacock hair. Tahiti Black Pearl Black Pearl gives people a vivid style.
This kind of pearl is traditionally called black pearl, but their color series consists of metallic silver-the color of pencil lead. In this series of colors, they are refracted by light, accompanied by overtones of different colors, such as green, deep purple or sea blue. In fact, at present, there are few pearls formed naturally, which can't meet the needs of the general public, so people have applied the principle of natural pearl formation and developed artificial pearl breeding. Therefore, consumers should pay attention to distinguish whether they are natural pearls when purchasing.
