This apparently eye clean and very bright oval is mostly yellow with a wash of green. I discovered, with my spectrometer, that it contains copper as a chromophore and that is interesting. But I don’t know how much difference it makes in the color of the gemstone. Besides any color influence it might have, copper might also help make the gemstone bright, but I don’t get the eye candy feeling with this more reserved oval. There are no problems with its quality of crystal like there is with many cuprian gemstones. The gemstone weighs 3.49 carats.
