Physical Properties of Feizhoucui
Colour:
Green
Comment:
Characteristic color is primarily attributed to barianâchromian muscovite, occurring as vein-like or spotted associated minerals within a quartz matrix. Green hue arises from Cr3+ absorption bands at 610â625 nm and 430â460 nm, while Fe content exerts a minor influence by inducing a red shift of the ~518 nm absorption minimum.
The standard classifies âFeizhoucuiâ into five color groups based on the dominant hue: white, green, red, yellow, and multi-color. Among these, the green variety is the most common and popular, largely due to its semi-transparent appearance and the striated distribution of green portions, which together create a resemblance to jadeite jade.
