I am seeing yellow in natural light and my yellowish light, but I know this is the type of tourmaline that will make a debate out of whether it is a slight greening yellow or a yellow. I would probably vote for a label of a fine medium pastel yellow in all its glory, but the cut between yellow and green varies between people. Tourmaline is also very sensitive to the quality of the light when it comes to crossing over into the green zone and becoming much more common. Common color or not this delightfully clean gemstone has great crystal with the commensurate flash and brightness. It weighs a healthy 3.59 carats.
