GIA has proven innovative criteria demanding quantitative chemical analyses to determine geographic origin for these tourmalines. These conditions ended up according to quite a few hundred samples from acknowledged resources spanning the three international locations. Hugely precise and precise quantitative elemental concentrations for Cu, Zn, Ga, Sr, Sn, and Pb are obtained with laser ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS). These data can then be plotted being a function of elemental focus for correct geographic origin determination.
, 1991) and easily surpasses the intensity and hue of indicolite’s Fe-relevant blues. A few years of trace component analyses at GIA have demonstrated that Cu happens in lots of gem tourmalines within the number of solitary-digit parts per million by pounds (ppmw) to tens of ppmw concentrations. Even so, these kinds of lower amounts of Cu is not going to create the Paraíba-like color; not less than several hundred ppmw Cu are necessary for that. Merkel and Breeding (2009) noted that peaks near seven hundred and 900 nm in obvious and in the vicinity of-infrared absorption spectra can be beneficial in evaluating the contribution of Cu if the stone also is made up of Fe. Mn, another component mentioned from the LMHC definition, can produce purple and pinkish hues when together with Cu, thus impacting the color appearance of Paraíba tourmaline.

Trace Elements: The vibrant hues of Paraiba Tourmaline are attributed for the existence of trace components, particularly copper and manganese, inside the crystal framework. These components connect with the tourmaline’s chemical composition to make the gemstone’s one of a kind neon or electrical hues.
Purely natural Paraiba tourmalines have to be cut to be certain They can be industry-deserving. Experienced cutters Lower these tourmalines via heated slicing, which ensures the many unwanted portions of the tourmaline are eliminated devoid of harmful the fragile Paraiba tourmaline.
