They are rich in types and shapes!

According to the origin and production environment, pearls are divided into several categories:

Natural Pearl Family Genealogy
BAOYUE PEARL’s “Natural Pearl Family Genealogy” chart facilitates everyone’s clear and intuitive understanding of pearl varieties and classifications. I will write a separate popular science article about the extremely rare pure wild pearls.

Natural Pearl Category

1. Seawater Pearls: Deep Sea Pearls

South Sea Golden Pearl:  South sea refers to Southeast Asia, a concept centered on China. During the Ming and Qing Dynasties, the coastal areas south of Jiangsu and other places were collectively referred to as "Nanyang", including the Malay Islands, the Philippine Islands, the Indonesian Islands, and the coastal areas of Indochina and Malaysia. Come to peninsula and other places. The unique conditions of this sea area with pure water, suitable water temperature and good air produce high-quality pearls. South Sea gold pearls, South Sea white pearls and Tahitian black pearls are all South Sea seawater pearls! The biggest feature of South Sea pearls is their large size (10-20mm), very good pearl luster, thick bead layer, rare production, very precious and become the most popular variety in the world! In particular, South Sea gold pearls are known as the "King of Pearls"!

The color of gold beads has several standards: light gold, medium gold, and rich gold. The price varies greatly depending on the quality and color!

The pearls produced on each island have different characteristics. For example, the Philippine gold pearls and Indonesian gold pearls, which are both South Sea gold pearls, are very different! Philippine gold beads are known as the fighter among gold beads. The richest color is their biggest feature. Insiders call them "abnormal gold". The richness of good-quality gold beads can even be comparable to the color of 999 gold, and the pearlescent luster is like silk. Smooth, thick bead layer, very expensive! The color in Indonesia is slightly lighter, although the color is not as rich and the pearl layer is not as thick, but the pearl skin is usually relatively clean and smooth, and there are relatively fewer pinhole defects! The appearance is also very beautiful, and the price is cheaper than Philippine gold beads.

South Sea White Pearl: (Australian White Pearl, Australian White) is the best type among all natural white pearl varieties! Comes with a noble temperament! Jewelry is the most appropriate way to describe the luxury and elegance of Australia White! The mother oyster is the white butterfly oyster, which is the largest pearl oyster in the world. Generally, the size of the white pearl oyster is above 10mm and can reach up to 20mm. The larger the size, the rarer it is and the more expensive it is! The mother oyster is very delicate and very picky about its growth environment and water quality. Only a small area on the northwest coast of Australia can achieve the growth conditions of Australian white oysters.
Australian white pearls are divided according to quality: ordinary Australian white pearls-Phoenix-Venus.


Tahitian Black Pearl: It is cultured from a precious black saucer mussel (a rare mussel that only grows in natural, pollution-free Polynesian waters). It has varying degrees of gray with... Different phantom colors make pearls more unique. In addition, the requirements for the breeding environment and pearling process are very strict. For every one hundred black disc clams that culture pearls, only fifty can successfully cultivate pearls. Only five of them are perfect, so every pearl is unique. Extremely precious.

Among them, the rarest and most precious among Tahitian black pearls are green black pearls, commonly known as: malachite green! The production is very small! expensive! Unforgettable!


2. Salt water pearls and shallow sea pearls

Japanese Akoya Pearls: Akoya pearls are produced in Japan. The Japanese pronunciation is similar and they are also called "Akoya". They are among the best in artificially cultured pearl technology in Japan and the world! There is a layer of calcium crystals on its surface. This kind of crystal is very rare and makes the surface very bright, so everyone calls it "little light bulb". Akoya's biggest features are: pink color and small size (diameter 3-8.5mm) , pearls are bright! It is loved by many women and very popular in the market. It has a fresh temperament. It does not have the luxury and nobility of South Sea pearls, but it has exquisite gentleness and is very suitable for daily wear and commuting!

There is also a silvery-grey-blue variety among Akoya seawater pearls called "Matoma"

Japanese Mabe beads: Mabe beads are different from ordinary pearls. They are semi-circular and are also called Mabe beads and steamed bun beads. Usually, the physical composition of seawater pearls and maple pearls are the same, but the growth process is different. Mapei pearls are actually a kind of regenerated pearls. After collecting cultured pearls, a semicircle is directly inserted into the inside of the maple shell. The half-shaped bead core is placed on the inner wall of the mother-of-pearl, and the nacre layer wraps the outer bead core layer by layer to form a semicircle. Cultivation of maple pearls occurs during the last stage of the life of the mother-of-pearl oyster. Mabe beads are usually as small as 10mm in diameter and as large as 20, 21, 22mm or larger, with shapes such as round, drop-shaped, oval, heart-shaped and special shapes, etc., and colors: white, pink, silver-grey blue.

Southern Pearls in Hepu, Guangxi, China: The history can be traced back to the Han Dynasty. It refers to Hepu County in Guangxi, which is under the jurisdiction of Beihai City. The pearls produced here are collectively called Southern Pearls. The most famous of the Southern Pearls is: Beihai Jinxia Pearl, which has been cultivated and cultivated through many years of scientific research. , North Sea pearls already have a variety of specialty pearls, mainly pure seawater cultured pearls and freshwater and seawater mixed hybrid cultured pearls. It is worth mentioning that the famous Japanese Akoya saltwater pearls were actually discovered in Hepu County, Beihai, Guangxi a hundred years ago.

3. Freshwater cultured pearls: Freshwater seedless pearls

Freshwater seedless pearls: Freshwater pearls refer to pearls produced in lakes. 95% of the world's freshwater pearls are produced in China. Pearl production areas are mainly concentrated in Zhejiang, Jiangsu, and other southern regions. Zhuji, Zhejiang is known as the "Hometown of Freshwater Pearls in China" and has a professional pearl market that accounts for 75% of the world's pearl trading volume.
Compared to seawater pearls, freshwater pearls are more colorful. In addition to white, there are also flesh pink, light orange, lavender and rich purple colors that are unique to freshwater pearls and are very cost-effective. Freshwater pearls were also called "Eastern pearls" in ancient times because they are seedless. Therefore, the quality of freshwater pearls is usually inferior to that of seawater pearls. The quality is uneven, so the price is cheaper. We use pearls as raw materials to produce cosmetics and oral medicine. The pearl powder is made from seedless pearls.

Edison freshwater nucleated pearl: It is a freshwater nucleated pearl developed by a pearl company in Zhejiang. The cultivation technology of Edison pearl can be said to imitate the South Sea pearl. It also implants a small nucleated mold in the mother-of-pearl, and then makes it The nacre secreted by the mother oyster wraps the core mold layer by layer and grows into a pearl. Edison pearls are rich in color and have the same color types as freshwater pearls: white, flesh pink, purple, orange and other naturally occurring colors.
To summarize the characteristics of Edison pearls: round shape, large diameter, rich colors, relatively rough cortex, many epidermal growth lines, and the price is not too expensive.


Freshwater Akoya nucleated pearls: Freshwater Akoya is a new technology in the past two years. The quality of good freshwater Akoya is comparable to that of seawater pearls! Although the cultivation method is the same as Edison pearls, they are both freshwater nucleated pearls, but there are still differences. Edison pearls implant the bead nucleus into the clam when it is a larvae. Unlike seedless freshwater pearls, a mussel Only one Edison Pearl can be produced. For "freshwater akoya", two years after the Edison pearls have grown, the clam body is opened again and six bead nuclei are implanted in the mantle on the side of the pearl clam. This process is very technically difficult and improper operation can easily lead to the mother's death. If the oyster dies and the pearl nucleus is implanted in an improper position, it will directly affect the uniform secretion of nacre and affect the quality of subsequent pearl growth. The advent of freshwater akoya still poses a big threat to Japanese seawater akoya. It is beautiful and cheap but only a fraction of the price of seawater akoya.

Finally, here is another picture to simply and clearly classify pearl grades: judging the quality grade of a pearl from the shape of the pearl - the pearlescent luster - the degree of flaws.
