As you may know as a mineral collector from Brazil, this country has so endless amounts of minerals (especially tourmaline) that it is often impossible to get an exact locality if you don't know it.

T 67 could be from Cruzeiro Mine, T 99 from Pederneira Mine, but maybe also from Cruzeiro ... I'm not the best expert for the many tourmaline mines in Brazil but I think most answers will be like mine and that each specimen could be from several mines. I think only a few of the Brazilian tourmalines are distinctive, e.g. the pink/red from Jonas Mine, the sometimes hollow green ones from Urubu Mine or the very best of the best of multi-coloured Pederneira crystals. I think most of your specimens could be from several localities, most of them are in the state of Minas Gerais ...

Regards
Tobi
