by simplysplendid » Jan 6, 2009 http://www.atggems.com/Paraiba.htm ? The AGTA certificate on the website says so. I had always thought that they are supposed to be neony and pricier? The reason I am asking is because I saw similar tourmalines at my jeweler''s (but much better clarity and cut) and according to my jeweler, the cutter that consigned the tourmalines to her says they are from Paraiba in Brazil. My jeweler also showed me an oval (approx 6 ct and according to her cutter, also from Paraiba in Brazil) that is much nicer in terms of colour than the one shown in the atg website and the colour looks like the green tourmalines set in a tiffany necklace that was on one of the blue books (I can''t seem to find a picture of it). How much should I expect to pay for a 6ct green tourmaline?
