    RARE GEMSTONE: BRAZILIAN PARAIBA TOURMALINE - 2.62 CT
    Batalha Mine, São José da Batalha, Salgadinho, Paraíba, Brazil
    Tourmalines from the Mina da Batalha in the Brazilian State of Paraíba are extremely rare and highly prized. The 1989 discovery of Paraíba Tourmalines, with colors of unwavering intensity, set off frenetic mining activity until the now-famous hill (only 400 x 200 x 65 meters high) was almost razed to the ground. Other deposits were found in the Paraíba region but overall production has never been large. Paraíba Tourmaline's color is due to Copper, an element never before observed in Tourmaline; additionally it often contains Manganese. The interplay between these two elements creates intense colors: Copper is responsible for the coveted radiant blue, turquoise and green hues, while violet and red tones are caused by Manganese. Paraíba Tourmaline scintillates: glowing intensely even under low light, their color is "electric" or "neon". This outer-worldly color has made Brazilian Paraíba Tourmalines amongst the most sought-after, and expensive, gemstones in the world. And although other deposits of Paraíba-like Tourmalines have been discovered in Africa, the color intensity of the Brazilian Paraíba is unprecedented and has never been equaled. This fine gemstone is a 2.62 carat vivid green-blue, Portuguese oval that measures 9.27 x 7.38 x 5.55 mm. A GRS certificate stating that it is indeed a Brazilian Paraíba Tourmaline accompanies it. Bright & lively, this is a beautiful example of a rarely encountered and highly prized gemstone - it is the standard against which all Tourmalines are judged: the pinnacle of colored gems.
