Freshwater pearls come from oysters that mature in non-salt water (a lake or pond, as opposed to saltwater from the sea). Almost all freshwater pearls are cultured in pearl farms. Their unique shape, wide range of colors combined with attractive prices and captivating characteristics have made them a favorite among jewelry designers, shoppers and connoisseurs of pearls.
Another way, to meet the needs of women, people have models of pearl farming, also known as artificial pearls. If only observing the appearance, natural pearls and cultured pearls are very similar, difficult to distinguish. However, their structure is different, distinguished by the core and the outer layer of jade. Artificial pearls are implanted from a piece of mantle epithelium made up of other triangular shell mussels of the same type, with a very high success rate, freshwater mussels were able to give pearls up to 80 pearls in a period of time. The culture period is very short compared to natural seawater pearls.
The most obvious difference is the environment where saltwater pearls and freshwater pearls form. In addition, when observing a saltwater pearl and a freshwater pearl, it is often seen that there is a difference in luster and reflective nacre, saltwater pearls have a much brighter luster than freshwater pearls. Each saltwater mussel only creates 1 unique pearl. Because of the complicated and long-term culture process, and the process of processing and dyeing to get the desired shape and color, saltwater pearls are often highly valued than many freshwater pearls.
