Tourmaline – Natural, Faceted, Pink, 16.24 ct

This is a huge stone for a pink tourmaline of this type from Afghanistan. It is very brilliant, and also very dispersive, showing distinct spectral color flashes. I even managed to capture one in the photo in the upper right. This stone also seems to have a fairly pronounced color change that ranges from being a bit more saturated pink than the photo shows to a pleasing yellow or slitly pinkish yellow under indoor incandescent light. I think I was seeing a 90%+ color change in this stone, but it was hard to tell with all the brilliance and diamond-like spectral flashes. Color: Baby Pink Changing to Yellow, Cut: Modified Brilliant with Supernova Crown and Faceted Girdle, Weight: 16.24, Dimensions: 14.21 x 17.71 mm.
