Comments: I obtained this well formed monoclinic xl of Ilvaite and a few other specimens on a very memorable trip to China. I travelled along the old silk road route, obtaining specimens as I went along that enhanced a very very enjoyable holiday. This mineral can easily be mistaken for Schorl if the crystal is misshapened.
