Tourmaline Var. Rubellite
Jonas Mine, Itataia, Minas Gerais, Brazil
Thumbnail, 2.1 x 0.8 x 0.5 cm
A very sharp thumbnail composed of several parallel crystals, exceptionally gemmy and with the vibrant classic color for this pocket. I left the pocket clay on the back face on this one, which you can see from behind. The crystal is so gemmy that you are looking right through it, in fact, to the mm-thick layer of attached kaolinite clay on the backside.
