How to identify seawater pearls? Natural seawater pearls are generally divided into Tahitian black pearls and Nanyang pearls (including Nanyang Baizhu and Nanyang Jinzhu) by a region with a general diameter of 9 mm or more. Akoya seawater pearls are mainly produced in Japan and China. The basic natural seawater pearls are all nucleated and cultured. The inside is a round-nuclear nucleus implanted in the shell. Therefore, the seawater pearls that are bred are generally round, and the akoya seawater pearls are generally round, and if it is Tahitian pearls, Nanyang pearls, except There are round, and there are also ovals and shapes. In comparison, the general seawater pearl is more round than the freshwater pearl. The freshwater pearl has a very round shape, most of which are nearly round, elliptical, oblate, irregular, etc., so the first one can be observed by shape. The second color is judged by size and color. For example, the black pearl color of Tahitian is generally not pure black. Generally, it has green, blue, silver and other colors. In addition to gold and white, Nanyang pearls generally have a diameter of more than 9 mm, 8- 9 mm is rare, and if it is small, it is suspected that it is not a sea pearl. The akoya seawater pearls are generally pure white, milky white, yellow, etc. China's akoya seawater pearls are generally below 8 mm, and Japanese seawater pearls can breed 8-9 mm in addition to small ones. Freshwater pearls generally have white, pink, and purple. Thirdly, through the epidermis observation, this is generally easier to understand and distinguish by looking at the real thing. Two kinds of seawater pearls, such as Tahitian black pearl and Nanyang pearl, can basically be judged by the color size and shape. It is more difficult to judge the white akoya seawater pearls and the white freshwater pearls. How to distinguish them? In addition to the shape and size judgments mentioned above, the skin is actually the best distinguishing. The akoya seawater pearls generally have concave and other concave natural ç‘•ç–µ textures. Relatively easy to present, the gloss is generally stronger than freshwater pearls, mainly with a sense of hydration and shine on the light, while the luster of freshwater pearls is softer, more versatile, and looks shiny and sinuous. The texture is different from the sea pearls. This suggestion can be more observed and changed.
