It looks like Kyanite on Quartz from Brazil
It is from Brazil. It is also on Quartz. However, it is not Kyanite.
A wild guess
Tourmaline is correct. Elbaite to be specific. The variety is Cuprian Rich or Paraiba, although technically this one comes from a neighbouring province to Paraiba; the Province of Perelhas. The very small ammount of copper is enough to cause intense colour, usually blue, sometimes purple and green also.
