In this specimen we can observe two very well defined anatase crystals, with the shapes of the tetragonal dipyramid truncated at the vertices by pinacoidal faces. The shine is excellent and they have an almost black color but with navy blue reflections when the light hits them. They are arranged in a very aerial way on a rock matrix covered by small tabular b alvite crystals between transparent and translucent and very brilliant.
