My impression is that there is just one termination in the photos. Yes, there are different angles to be found on tourmaline pyramidal faces. It would require finding a matching one to make the reflection comparison. Find one that matches and has the same color and you may have a locality match.

Maybe Sahatany Valley, Madagascar. Almost sure it is not Malkhan, it does not match the epoque nor the color tonality.
