If you still have the bangles and wear them on a regular basis, I'd strongly recommend not doing so. When I posted a pic of my treated bangle to get opinions on a Chinese forum, the general consensus was that I should remove it asap, because these bangles are harmful to your health.
Good point about not wearing "treated" jade on a regular basis. So am I correct in understanding that a lower quality untreated jade would be better to wear than a higher quality treated jade? ...and if it doesn't have those "pitted type marks" when viewed through a jewelers loupe can we assume that it's not treated?
