We have never seen such a piece in our 22 years of experience in Tanzania: it consists practically only of tanzanite crystals, and indeed of large and very many honey-yellow excellent Magnesio-Axinites so completely that they are extremely rare to find. To be distinguished from the tanzanites practically only by the strong fluorescence under UV-long. In between many graphite crystals and a few calcites. The Tanzanite and Mg-Axinite have a very high luster
