The color of Emerald A will not change, it will take hundreds of years to change, or it will become greener because of decades of wearing. Green scattering means that you bought artificially treated jadeite. Jmwgj520 suggests that you stop wearing it, lest it is bad for your health.
Pure natural with light purple, which is what we call violet, is better. Eight out of ten jade bracelets are made of stone powder and pigment. This is not all natural. Of course, what I want to buy is pure natural product A, which is difficult for insiders who don't know. Or what you bought was shoddy.
