Chinese ancient jades contain a wealthy connotation of historical culture and humanity arts. People of all ages are favorably disposed toward them with incomparable love. In recent decades, with the booming cross-strait economy, setting off a wave of collection of jade, due to limited jades it is difficult to meet the needs of the market. Meanwhile, pseudo-ancient jades emerged in the market. With scientific and technological progress, the qualities of pseudo-jades are looked so real that a lot of collectors and connoisseurs are deceived. While researching jade, it often faces the problems of identifying authenticity. Through studying scholar researches and expert experiences, I would like to explore contemporary selection of making pseudo-jade material by imitators and the methods of making pseudo-ancient jade by new technologies, and summarize some personal jade's identification and collection experiences to consult with collectors and connoisseurs.
