Black tourmaline with pale-blue translucent aquamarine on microcline-muscovite matrix from classic Brazilian locality. The crystals show deep corrosion in that is typical for the locality. The contact with matrix is recrystallized. It is a floater specimen that was lying freely in the pocket. I acquired this specimen from the famous Slovenian mineral dealer Miran Rezar who brought them from the locality in summer 2016.
