This is a gemstone most people have never seen, it is very rare, in the early 1980's the Jose de Batalha mine in the Brazilian state of Paraiba. A man named Hetorita found a tourmaline color never seen before. This new tourmaline color was a bluish/green different than any color ever seen. The gem had a neon glow to the color that is really beautiful. After testing this new stone we found that the color and neon glow was produced by copper, manganese and a small trace of gold. The new deposit of tourmaline was a big hit in the gem market and by the time the 90's hit the mine had dried up. Today the Top Gem World Class stones are going for $25,000 per carat and up. Sorry to say this isn't one of them TGWC stones, It has the color and the glow but it not as clean as it could be. This gemstone weights: 2.01 carats, cut in an oval shape. The measurements are 7.06 x 9.10 mm and the clarity: SI 1. Tourmaline is usual an included gemstone it's what they call a class three. The class III means these gems is normally medium to heavily include. Tourmaline is 7.5 on the Moh's hardness scale and is double refractive. This gem list at 1.66 on the refractive index. This is a true Paraiba Tourmaline from Paraiba, Brazil. Not everybody can afford or would pay for this gemstone but if you’re a collector and don't have a Paraiba in your collection here's your chance. I have three of these gems in my collection, two are really small one is a 1.44ct and the appraisal on it is good. I give a ten (10) day inspection period on all gems and jewelry for a full refund.
