Is there a specific measure on a spectroscope that denotes the origin of Paraiba Tourmaline containing both Maganese and copper. Does the. neon blue effect only arise from heating or is it a naturally occurring phenomena? Is themost saturated colour of Paraiba predominantly Brazillion? Jennifer
I have also Wonder if the amount of heating produces different colors of blue?.
The heated Paraiba tourmaline’s I purchased years ago, faded due to being heated. I was told many many years ago, tourmaline’s were not supposed to be heated? I believe sometimes the blue color may come from iron and that is why they have to be tested for the copper content.
