What's the difference between Nanhai pearls and Nanyang pearls? Which is more valuable? The South China Sea and Nanyang are two different regions, and Hainan Island belongs to the South China Sea. Generally, Hainan pearls are mainly seawater pearls produced in China, or Nanzhu, with a general specification below 8mm, which is exquisite, beautiful and generous. Nanyang pearls are produced in the South Pacific, including Australia, the Philippines, Malaysia, French Polynesia and other places. Their colors are white, noble gold and mysterious black during the Spring Festival. Generally, the diameter is over 9mm, the quality is generally good, and the value is more than ten times higher than that of seawater pearls in China. Therefore, Nanyang White Pearl, Nanyang Gold Pearl and Nanyang Black Pearl (commonly known as Tahiti Black Pearl at present) are more valuable for collection. The value of Nanyang pearl has doubled this year compared with the previous two years, and it is expected to continue to increase in value in the next few years! I hope I can help you!
