Analysis of the difference between freshwater pearls and seawater pearls

Pearls are divided into seawater pearls and freshwater pearls. Pearl jewelry gives a sense of grace and luxury, and is the favorite of female consumers. When buying pearls, I often hear the clerk introducing seawater pearls and freshwater pearls. Both seawater pearls and freshwater pearls are pearls. The pearls are divided into seawater pearls and freshwater pearls. Pearl jewelry gives people a sense of grace and luxury and is consumed by women. Favorite. When buying pearls, I often hear the clerk introducing seawater pearls and freshwater pearls. Both seawater pearls and freshwater pearls are pearls. So what is the difference between freshwater pearls and seawater pearls? The breeding technology is different, so the structure is also different. Freshwater pearls are non-nuclear and all ingredients are composed of nacre. Therefore, if freshwater pearls are used to make pearl powder, there will be no other substances mixed. The seawater pearl has a nucleus, and its nucleus is generally ground from the shell of a pig's hoof. The pearl is only covered on the surface, and the thickness is 0.1~0.3mm. The growth period is about 1 year (freshwater pearls up to 4~5 years), so seawater The pearls around the pearls are thin. If all seawater pearls are used to pulverize, there will only be a small amount of pearls, most of which are shell powder, so the medicinal or cosmetic effect is not good, but if the seawater pearls are processed into 100% pearls For powder, the core must be removed first, which is costly and difficult to process. In addition, most seawater pearls have an inner core, and their shape is easier to control. Most of them are relatively regular, so they have higher value when used as decorations or hand ornaments. Only a few irregular seawater pearls with no decorative value are used as pearl powder. Therefore, the production of seawater pearl powder is not high. In the Pharmacopoeia, seawater pearls and freshwater pearls can be used as medicine equally. Scientific analysis found that the composition of freshwater pearls and seawater pearls are different. Freshwater pearls have 3 kinds of amino acids lower than seawater, and 2 kinds are the same. The first point: Pearl powder is processed by scientific methods from the effective ingredients of pearls. Among them, seawater pearls are bred in the sea with very natural minerals and various nutrients. Seawater pearls are in the cold sea. The inside makes seawater pearls more cooling, moisturizing, anti-inflammatory and other effects; freshwater pearls are produced in shallow waters such as lakes or artificial ponds. The growth environment of 　　　　 is different, and the minerals and trace elements contained in them are definitely different. The effects of the two are definitely different. In recent years, freshwater has been seriously polluted, and the effect of freshwater pearl powder has been much smaller than that of seawater pearl powder. The second point: The output of seawater pearls is extremely low. Generally, only three shells can produce one seawater pearl; the output of freshwater pearls is relatively high. According to the introduction of Yueyang, Hunan, the largest freshwater pearl cultivation base in the country and even the world, the average Each shell can produce 6-8 freshwater pearls, so it can be imagined that the price of seawater pearls is much higher than that of freshwater pearls. The third point: and the most critical point. Due to the development of China in the past ten years, environmental pollution has become more and more serious. In addition, freshwater aquaculture mainly relies on feed to raise the output, but its products contain high inorganic substances, which have the effect of beauty and health care. The content of organic matter is very low. The seawater has natural minerals and nutrients, and the pollution of the seawater is relatively low (especially the pollution of the North Sea is even less, and the air in the North Sea is also one of the three best cities in the country, known as the country's largest oxygen bar). , Pearls are relatively natural (cultured seawater pearls are also provided by the sea itself instead of being raised with feed). After being bred by the sea, the low-yield seawater pearls can guarantee its organic content, which is very important for beauty and health care. Key role.　　　　 Fourth point: The switches of seawater pearls are relatively round and have good luster, while the switches of freshwater pearls are mostly oval and rice-shaped. The luster of seawater pearls is more crystal clear and radiant, while freshwater pearls lack this soft luster.　　　　 Each variety of pearls is good or bad, and it does not fully indicate which seawater pearl or freshwater pearl is better. If you choose pendants and earrings, you can choose seawater pearls, which have larger particles and show more temperament; if it is necklaces, hand ornaments, etc., choosing freshwater pearls is also excellent. Therefore, whether seawater pearls or freshwater pearls are better depends on personal choice.　　 The above is the author's summary for you about the difference between freshwater pearls and seawater pearls.
