This Barion cushion, designed by Graham, weighs 4.70 carats and mixes the a/b axis brownish color and the c axis color I call blackberry blush very well. I think that it is from Mozambique and when copper was discovered, I thought that this gem, because of its color, might be colored by copper. My spectrometer did not show any absorption by copper in the gem. It is still a nice clean stone with a different color mix.
