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 enjoyable holiday. This mineral can and is easily mistaken for Schorl especially if the crystal is out of shape.
