Different pearl producing areas and different shellfish are different. Let the Chinese Jewelry Merchants Network Xiaobian bring everyone to see how to distinguish seawater pearls and freshwater pearls. We can combine the following methods to distinguish seawater pearls and freshwater pearls:
1. Distinguish between seawater pearls and freshwater pearls by the color of pearls: Among the seawater pearls, the color of Tahitian pearls is generally green, blue, transparent, or silvery gray. It is better to distinguish; Nanyang Pearl The color is generally only gold and white; the most common akoya seawater pearls are white, white powder, a small amount of gold; freshwater pearls are mainly white, pink orange, pale pink, pink purple, purple.
2. Identify the seawater pearls and freshwater pearls by the shape of the pearls: Generally, the akoya seawater pearls have a small particle size, and the nuclear cultures are basically round and round; while the Nanyang pearls and the Tahitian pearls are also nuclear cultured. However, the larger diameter shape is relatively difficult to control, and there are round and perfect circles. The value of the perfect circle is the highest; freshwater pearls are not nuclear because of their non-nuclear culture, and most of them are not round. Oblate, elliptical, close to a perfect circle, or completely round like a sea pearl, is one of the best, with the highest value.
3, through the size of the pearl to distinguish between seawater pearls and freshwater pearls: the size of each pearl is not absolute, but can be combined to judge the variety of pearls, Tahitian pearls and South Sea pearls in seawater pearls, generally 9- in diameter Between 16mm, akoya seawater pearls generally have a particle size of 4-9 mm, while freshwater pearls have a wide range of diameters, generally between 5 and 11 mm in diameter. With the continuous development of nourishing pearl technology, in recent years There are relatively large freshwater pearls with a particle size between 12 and 16 mm.
4, through the skin of the pearl to distinguish between seawater pearls and freshwater pearls: Tahitian pearls and South Sea pearls can generally be distinguished by color and size. Here, we will focus on how to distinguish akoya seawater pearls and freshwater pearls. Based on the shellfish and environment in which pearls are born, akoya seawater pearls and freshwater pearls are still easy to see some easily recognizable "spirits", and the akoya seawater pearls are bred. The species is Marsh's shell, and the akoya seawater pearl is more likely to produce a surface texture. The surface will see the natural growth texture or wrinkles formed by the seawater pearls. There are bulging or concave pinpoints, and the freshwater pearls look like awkward places. There are very few ridges that are raised and relatively smooth. It is impossible to have a string of akoya seawater pearl necklaces that do not see any flaws on the market. Therefore, a string of akoya seawater pearl necklaces with subtle flaws are among the best quality.
It is not very difficult to distinguish between seawater pearls and freshwater pearls, combined with color, shape, size and skin. Although not everyone can see it at a glance, the focus is on more research, more understanding, more understanding, natural mastery, general expert By the naked eye, the basic 98% can be judged correctly.
