Feicuitai is a kind of jadeite completely belonging to ice species. Its grade is lower than that of high-ice jadeite, and it is between glass and ice. It has the characteristics of "three points moist and seven points cold" and looks as crystal clear as ice. There are great differences in texture between the common gem-grade ice jadeite and super varieties in the market. The water for planting jadeite is very good and transparent, but there will be some noise in it.
