There was only one pocket found, which produced this kind of shaped tourmalines. Almost each crystal discloses schorl crystal as seed. I haven’t seen anything coming out from Burma like this before. The tourmaline crystals seem to have reached the ceiling of the pocket while the lower prismatic part of the crystals seem to be dissolved or altered by probably contact with
some fluids after the primary epitaxy. However this is a very interesting and rare specimen!!
