Very rare Blue Amphibole Natural Quartz crystal on matrix

This is a fully natural quartz point on matrix, with a smaller crystal on each side. No cutting or polishing done. Usually these have to be cut into the shape of a quartz point, because the inclusions are in a large mass of quartz, very seldom do incredibly rare inclusions like this blue and white amphibole fill a whole natural crystal like this, and even more rare is it able to be mined still attached to it's host rock (matrix). This is a truly special and unique piece, search and try to find anything like it! I can't.

Look at pictures very closely to see condition. There is a chipped termination face on the rear side of how you would display it. From the front (best) side, it isn't going to be too noticeable in a display. I believe the beauty of the natural, unpolished look of the crystals on matrix beats any cut/polished pieces which are so much more common.

Hand shows scale for now but I will add exact dimensions/weight etc later. It's about 1.5" square. From Brazil.
