Everyone knows in the tourmaline family that the most distinguished is the magical Paraiba tourmaline. This tourmaline has beautiful electro-optic light and a bright, brilliant blue color. Therefore, with the discovery and famousness of this tourmaline, some blue tourmalines were quietly put on the cloak of Paraiba. But in fact, the two are not equivalent. Blue tourmaline is more expensive because it is rare, but it is far worse than Paraiba.
According to the scientific identification point of view, the composition of tourmaline ore contains a certain amount of copper, which can be regarded as Paraiba tourmaline. Experts believe that the ParaÃba copper element is the cause of neon blue (electrical flint-like luminescence), that is to say, the blue tourmaline color, although the iron element can also cause neon blue light, but if there is only iron element, the authority still Can not issue a "Paraiba" certificate.
Blue tourmaline was previously called é›é’碧玺, although its color is from lavender to blue, dark blue, and lake blue, but the ore of its ore does not necessarily contain copper. Therefore, even if the blue tourmaline is bright in color and the internal texture is clean, it cannot be said to be Paraiba. Blue tourmaline is more popular because of its low output, so its market price is also relatively high!
