    Fine Gemstone: Paraiba Tourmaline - 1.80 Ct.
    Batalha Mine, São José da Batalha, Paraíba, Brazil

    Tourmaline from this small deposit, the Batalha Mine in Paraíba, has impacted the gem trade in larger ways than these relatively small workings would imply. Its impact continues to reverberate, even though the original occurrence is worked out. Traces of Copper and Manganese are involved in producing the stunning teal blue hue of the stone. In Tourmaline, there is no finer or more valuable color. GIA Report # 5171135572 attests that this modified brilliant oval cut is Brazilian in origin, and shows transparent green-blue color. It was cut from rough obtained in 1989 and the cutter states that it was cut from natural Batalha Mine material and that it was not heated or enhanced.
    Measurements: 8.83 x 6.56 x 4.83 mm, 1.80 ct.

    Accompanied by GIA Certificate #5171135572
