Color in tourmaline is truly a wonderful trip, but you have to be careful about coming to conclusions about its chemistry based on color alone. Two areas of major confusion are the coloring of Dravite the species with either chrome or vanadium to make green, (chrome tourmaline is really colored by vanadium) and the color of Elbaite the species with copper and iron (they can produce the same cyan color). Having said this I am still going to venture out on a limb.
This pink purple standard round brilliant is representative of a family of color that grades from just a touch of purple in pink to purple. It comes in the faintest tone level to the deepest tone level and always contains copper as a chromophore. I have technical problems with confirming this with my spectrometer, due to its limited spectral range and an interesting effect of manganese, that is missing three electrons (Mn+3). It can sometimes have an increased amount of absorption in the infrared. Based on this less than stellar support, I declare that this moderately include round be admitted to the droplets with the honor of being a rare color of cupian extraction. It weighs 1.52 carats, has a medium light tone value and good crystal between the scattered inclusions. It has just a touch of purple.
