Difference between Edison Pearl and Nanyang Pearl
1, origin: Edison Pearl is produced in Zhuji, Zhejiang, the hometown of freshwater pearls in China. The main producing areas of Nanyang pearls are the northern waters of Australia, the Philippines, Malaysia and Indonesia.
2. Output: Nanyang pearls can only be fished by sea, with limited resources, long breeding period and great difficulty, so its output is much less than that of ordinary Edison pearls.
3. Color: In addition to the traditional gold and white, Edison pearls also have special metallic halo colors such as deep purple, bronze and violet. Nanyang pearls are mainly divided into three colors: white, gold and black.
4. Size: Edison Pearl and Nanyang Pearl belong to large-size pearls. The average diameter of Edison's pearls actually reached more than 12 mm, and the largest reached 20 mm. Generally, Nanyang pearls are 9- 15MM in size. It is understood that the largest recorded pearl with a diameter of 2 1 mm is Nanyang Pearl.
5. Shape: Both Edison pearls and Nanyang pearls are cultured with nuclei, and the perfect circle rate will be higher, so it is difficult to distinguish them only by shape.
6. Gloss: Edison pearls are freshwater pearls, and Nanyang pearls are seawater pearls. Generally speaking, the luster of Edison pearls is not as bright and lasting as Nanyang pearls. The luster of seawater pearls is moist, while that of freshwater pearls is soft.
7. Skin: No matter Edison pearls or seawater pearls, most of them have natural growth defects, and few are perfect, with minimal defects or almost no flaws in appearance. If you look closely at the epidermis of Nanyang pearls and Edison pearls, there are still differences. The natural growth texture or wrinkles of Nanyang pearls have convex or concave needle holes, while the places where freshwater pearls remove defects have few convex wrinkles, which are relatively smooth.
8. Price: The price of pearls depends on the variety, shape, size, quality and color of pearls. In terms of rare output alone, Nanyang pearls are better than Edison pearls. So generally speaking, the price of Nanyang pearls is more expensive than Edison pearls.
Advantages of Edison pearls
Edison pearls are characterized by large particles, bright luster and rich colors. In addition to the traditional gold and white, there are special metallic halo colors such as deep purple, bronze and violet. Some single pearls can be mixed with several different metallic colors. Edison's top quality can be compared with foreign top seawater pearls. There is a jargon in the pearl world called "seven pearls and eight treasures", which means that pearls with a diameter of 7 mm are only the average size, and pearls with a diameter of more than 8 mm are jewels. This has always been used to describe the traditional freshwater seedless pearls in China (all mariculture pearls have artificial pearl cores). The average size of seedless pearls is naturally not as large as that of nucleated pearls. Generally, freshwater seedless pearls that can achieve perfect aurora after 9mm have only accounted for 3% of the output. Edison pearl adopts high technology and applies nuclear implantation technology to freshwater pearls, which greatly increases the particle size of freshwater pearls. As for why Edison's pearls are so bright, Pearlsue can't know, because this is a trade secret, and there are different opinions in the market. Maybe we should create some space for China.
The difference between seawater pearls and Edison pearls
1. Distinguish seawater pearls from Edison pearls by color: Edison pearls have gold, white and other special metallic colors such as deep purple, bronze and violet. The colors of seawater pearls are mainly white beige and champagne. , in the basic tone with pink, silver blue and other foil colors, not many bright colors.
2. Identify seawater pearls and Edison pearls by their size: the size difference between seawater pearls and Edison pearls is still very large. The particle size of seawater pearls is generally between 4 and 9 mm, while that of seawater pearls in China is generally between 5 and 8MM, and those exceeding 8 mm are rare. Because of the better culture technology, the size of Japanese seawater pearls is 8-9MM, but it is basically not more than 12 mm. The average diameter of Edison's pearls is actually more than 12mm, and the largest is 20 mm, so the size is more intuitive.
3. Distinguish seawater pearls from Edison pearls by luster: Due to the different growth environments of pearls, the luster of pearls produced is slightly different in appearance. The luster of seawater pearls has a different delicate feeling, which is brighter and more moist than Edison pearls, revealing from the inside out. The luster of seawater pearls is moist, while the luster of Edison pearls is soft and mild. However, if you don't know much about pearls, you may not know why if you look at the luster for a long time!
4. Distinguish seawater pearls from Edison pearls by their skins: The shellfish and environment that gave birth to pearls are different, because the skins of pearls are still somewhat different. The texture of seawater pearls is relatively dense, and growth textures or wrinkles can be seen on the epidermis. Appearance defects are mainly convex or concave pinholes, which are caused by sand or foreign matter entering the mussel. Freshwater pearls rarely have raised wrinkles where defects are removed. In addition, the appearance defects of freshwater pearls are usually mainly threads and pits, and different textures will be found when the beads rotate. There are few linear defects (even shallow lines) on the surface of seawater pearls, and the lines of freshwater pearls are very common. Therefore, seawater pearls and Edison pearls can be distinguished by looking at the skin defects of pearls.
