Gemmological Significance of Study on Secondary Reducing Fluid-Rock Interaction in Jadeite Jade Bench Deposit from Burma

The secondary reducing fluid rock interaction which happened in the jadeite jade from Burma makes the colour of jadeite jade changed to sage green, dim green or bluish green, and its transparence improved. Study on the fluid rock interaction is very important for the classification of the secondary colours, the variety division, identification, quality evaluation, enhancement of the jadeite jade, and also promote the study on the fluid rock interaction of the other kinds of jades.
