New Varieties of Freshwater Cultured Pearls and New Development for Techniques

At present, the ordinary and low quality freshwater cultured pearl products could not meet the fashional needs of the most consumers. However, with the further development of the cultivation techniques and process techniques, many new varieties of pearl appear in the pearl market. The characteristics of the new shapes of pearl are systematically summa- rized. Nucleated cultured pearls are more suitable to be produced for varied shaped pearls. Meanwhile, based on non-nucleated freshwater cultured pearl samples, the application of the appearance improvement for pearl by faeeted cutting technique,setting technique and carving technique are discussed, and the facet angles and time are also analysed. The oval pearl and waist pearl are setted by the CZ, and their appearances have great improvement and the increase in value. Finally, the carving technique is also discussed.
