I have one museum stone that is eye clean and the purple of a life time. I also have clean paler purple tourmalines that probably were partial heat treated from large, dark toned, reddish pebbles, that were found very early in Mozambique. But most purples are not eye clean. They all contain copper as a chromophore.
This beautiful purple tourmaline is cut as a standard round brilliant. But even this excellent cut for concealing inclusions can not hide the multitude of sparkles that come from inclusion. Still the purple has good saturation and the stone is bright and flashy. No purple tourmaline can be reject because it has less then perfect crystal and for not being eye clean. We welcome all to the place of droplets. It weighs 1.08 carats.
