Charlie was very impressed with this rare gem crystal of sillimanite, which he told me was the best he had seen, for combination of size and form. I cannot argue, as I have never seen but rounded pebbles of this material, from Mogok and not from India. The crystal is a little bit like a floppy wizards hat in form, but it is translucent and 3-dimensional, and actually displays quite well. I am inclined to fully trust Charlie about its significance in the absence of anything to compare it to out there.
