Cultured freshwater pearls are pearls which are farmed and created using freshwater mussels. These pearls are designed in Japan and the united States on a limited scale but are actually almost exclusively produced in China. The U.S. federal Trade Commission requires that farmed freshwater pearls be referred to as freshwater cultured pearls in commerce.The grafting process begins by picking a suitable donor mussel and cutting a strip of tissue from the mantle. This strip of tissue is then cut into three-millimetre squares. These squares are delivered to some technician who performs the operation. Unlike saltwater bead nucleation this technique is not considered difficult and technicians need only minimum training to execute the operation. The technician creates small incisions on the upper valve and inserts the tissue piece. A small twist in the tissue upon insertion is considered to create a higher ratio of round pearls. After the maximum quantity of grafts happen to be performed the mussel is flipped and the procedure is completed yet again on one other valve of the shell.Chinese freshwater mussels were once grafted approximately 50 times per shell or 25 times per valve. This practice was common once the industry mussel was primarily the cockscomb pearl mussel (Cristaria plicata). This mussel produced an increased volume of low-quality pearls that found be known as Rice Krispie pearls inside the 1970s and 1980s. More than a decade ago the freshwater pearl industry of China shifted production from your cockscomb pearl mussel on the triangle shell mussel (Hyriopsis cumingii). The triangle shell produced fewer pearls accepting only 12-16 grafts per valve for a total production of 24 to 32 pearls but produced pearls of better quality.
