The Paraiba Tourmaline
Its vibrant luminous color makes the Paraiba tourmaline an extremely sought-after gemstone.Hardly any other colored stone possesses the captivating luminosity of a Paraiba tourmaline.The difference between Paraibas and other tourmalines becomes apparent in the chemical composition of the mineral.The trace elements copper and manganese contained in Paraiba tourmalines are responsible for their radiant color. Depending on the ratio of these two elements, the hue of the gemstone also varies: with a higher copper content, bright turquoise colors appear, with a predominant manganese content, the color spectrum extends to bluish, violet hues.Due to their chemical composition, Paraiba tourmalines can only be found in copper- and manganese-bearing so-called pegmatites (coarse-grained, igneous rocks). The breathtaking beauty of a Paraiba tourmaline requires careful staging to best showcase the stones' assets.
