Yes, my spectrometer detected copper in this gemstone and I purchased it as a blue purple cuprian. I have stared hard at this standard round brilliant many times and I think I can see a fleeting hint of blue purple sometimes, but most of the time it is one of the purest of the pure, achroite. It is definite pure and with outstanding transparency. It weighs 2.17 carats.
