Jade Jewelry Industry associations understand that, after two years of development, China's freshwater

Pearl Standard physical samples coming soon. This is the healthy development of China's pearl industry has a positive effect.

70s last century, Chinese freshwater pearl culture technology breakthrough has been made to promote the rapid development of China's pearl industry. In 2007, China's output of 1600 tons of freshwater pearls, freshwater pearls cent of the world total, 95%; exports 208 million U.S. dollars, employing more than 30 million people, formed in Zhuji, Zhejiang, Suzhou Wei ponds pearl processing, wholesale and retail distribution center and Hunan , Jiangsu, Zhejiang, Anhui, Hubei, Jiangxi, 6 large fresh water pearl breeding base.

Quality freshwater cultured pearls which include color, size, shape, shiny, smooth finish, bead layer thickness (a nuclear Pearl) and other six areas. Certain period of time, "cultured pearl grading" the norms of Chinese pearl market, and technological progress has played a positive role. However, as time goes on, "cultured pearl grading" standard text gradually exposed a number of problems, the most important issue is the lack of physical standards for sample comparison. In the "cultured pearl grading", the pearl size, shape, beads can be measured and calculated thickness, but color, gloss, smooth finish is entirely sensory evaluation criteria, either enterprises or quality inspection organization Ye Hao, market, we all with a text based standard, but can not form a consistent opinion on quality levels. Pearl imminent physical reference material. In 2004, China Insurance Association submitted to the Standardization Administration of the "Research (complex) system, standard samples pearl" of the application and approved at the end of 2005 (standard samples Committee 2005 37).

Discussion group established a standard sample of three series: color, gloss, smooth finish; ultimately determine the standard sample size of 9 mm, round shape, and the development of a "standard samples 3SLC Chinese freshwater pearl quality evaluation system diagram" . As the pearl color changing, the research group according to research to select the most common and the most common white, red, purple three colors as a reference standard, gloss, smooth finish for the enforcement of national standards.
