Superior Tanzanite 3.35 Carat Blue Violet Exceptional ColorRound with excellent color tanzanite from Tanzania. This is a truly outstanding gem. One of the finest from the famed "Karl pit in D block". Gem cut in Tanzania by Steve on an old MDR machine which was the first machine on which Steve learned cutting. We will attempt to set up a cutting factory as export of rough over one gram is prohibited unless it has natural crystal shape. The overall rating is a 908 out of a 1000.
