More than half of the largest surface on this piece of hematite is coated with lovely pale purple crystals of strengite. They have an unusual appearance, both dull and sparkly at the same time. A loupe reveals that this is caused by the crystal form, as the individual crystals have a vitreous luster, yet they are organized into rough spheres whose crevices absorb most reflections. There are many other minerals present, likely including goethite, kidwellite, and rockbridgite. About half of the strengite is coated with a yellow-brown layer, likely more rockbridgite.
