This round standard brilliant weighs 10.93 carats. I think that yellow green is one of the brightest colors in tourmaline. Manganese and titanium with low iron has been proposed as the chromophores that color tourmaline, yellow green. Time and time again I have found that a beautiful polish can only partial explain this color's visual punch. Most of my yellow green tourmaline's personality remained unchanged when I put the spectrometer to them, but a few revealed a copper touch. This is one of them and ebay may push that to the limit, but the limit of my appreciation has been unchanged.
