Nanyang Golden Pearl, a precious deep-sea princess.
At present, pearls on the market are mostly divided into freshwater pearls and seawater pearls. Freshwater beads are mainly distributed in the middle and lower reaches of the Yangtze River, with almost no perfect circle, and are mainly divided into three colors: white, pink and purple. Its growth speed is fast, and it can grow from seedless to 7-8mm in 2 years.
Seawater beads are distributed in Hainan, Japan, Tahiti, Nanyang and other regions, and they are full and round. Mainly in pure white, gold, malachite green and other colors.
The growth rate of seawater beads is extremely slow, but because of this, its density is much higher than that of freshwater beads, which also makes the texture and luster of seawater beads better.

Nanyang, where is it?
When it comes to Southeast Asia, most people in China think that it is probably a general term for Southeast Asia by China in Ming and Qing Dynasties.
But the "Nanyang" here actually refers to the vast sea area from the South Pacific to Indonesia and the Philippines in the east and Australia in the west.
The waters from the southwest of the Philippines to kalimantan island and the waters near Indonesia are the most comfortable places for the growth of Golden Pearl in Nanyang.
Pinctada Nanyang
The mother shell of Lonicera edulis and Leuconostoc leucocephala belong to two branches of Butterfly.
The golden-lipped shellfish are very sensitive to the growing environment. The sea area where they live needs fresh air, clear water, suitable water temperature, open bay and few typhoons. Even the slightest change in water flow and temperature will affect the survival of golden lipped shellfish.
As the carrier of cultured pearls, the size and weight of mother shells will affect the size of cultured pearls.
Nanyang white pearl is the largest pearl oyster species in the world. Generally, the white butterfly is 25 to 28 cm long and weighs about 3 kg, with strong bearing capacity. The cultured pearls are huge and full, with thick pearl layer and smooth texture.
Nanyang Golden Pearl and Nanyang White Pearl have the same basic characteristics but add luster, and are also favored by big pearl lovers.
Cultivation of Nanyang Golden Pearl
Natural golden pearls are very rare in the world. Seawater pearls usually adopt nucleated culture, and the golden beads on the market are basically cultured pearl nuclear technology. The breeding cycle of Nanyang Lonicera edulis is long, generally about 5 years. Any change in temperature and seawater conditions will affect the growth of Pinctada.
The growth rate of Lonicera japonica is extremely slow, and it takes more than 18 months to cultivate mature golden lipped shellfish with implantable pearls.
It will take at least five years to finally cultivate a golden bead. The cultivation time is long, and the yield is extremely low, which leads to that the golden pearl is less than 10% of the total output of the white pearl.
Especially in recent years, the breeding environment of Nanyang Zhu Jin has been destroyed, and the output has dropped sharply. Since 20 15 years, the supply of gold beads has been in short supply, and the price increase has also approached the mainstream popular gems, with an annual increase of about 30%.
Nanyang gold-knowledge of color
The color depth of gold beads is not directly related to whether they are natural or not. The formation and cultivation degree of pearl color is mainly determined by the growth environment of mother shellfish.
The gold pearls in the Philippines are of the highest grade, with strong tea gold accompanied by turquoise color, which is what we often call pan-blue light. (The gold balls auctioned by Paspa Thunder usually come from the Philippines. )
Indonesia's golden beads are characterized by thick golden orange, which is what we often call red golden beads, but there is no colored metallic color.
The golden beads in Myanmar have the highest grade of yellow with turquoise, and the color in the auction is classified as yellow.
As far as color is concerned, it is as thick as real gold and as bright as sunshine. Zhu Jin is worthy of the title of "King of the Beads".
The Structure of Nanyang Zhu Jin
The above picture shows the structure of Nanyang Zhu Jin simply and clearly, which consists of nacre and nacre from the outside to the inside.
Among them, the nacre layer is composed of aragonite crystal and conchiolin composite layer. Conchiolin is an organic substance secreted by mother-of-pearl, while aragonite is a hexagonal translucent calcite crystal with a size of micron. (Nanyang White Pearl is the same as Nanyang Golden Pearl)
