I think that I have posted about how forgiving I am with purple tourmaline that are cuprian. Well this standard round brilliant just shrugs the concern off with a great eye clean body and a sparkling bright purple personality. A purple with fine saturation and a medium tone . What more could you want than that (larger size). Well we should count our tourmaline blessing and this is one of them. It came from Mozambique and I probably bought it before anyone realized that cuprian tourmaline came from Mozambique. One of the benefits of seeking different colors where ever that might lead me. It weighs .77 carats.
