This is a superb oldtimer with a fantastic luster, high transparency an dgemminess, and a unique blue coloration that sets it apart from most tourmalines out there, US, Brazil, or otherwise. The spectrum of blue here is really, to the eye in person, different. This is likely an old crystal, I am told almost certainly predating the 1940s, and it is in fine condition, nearly pristine. It displays in a showcase alongside Brazilian or Himalaya Mine tourmalines and is no slouch in that company. It is by far the best example I have seen for sale from old finds here.
