This specimen simply consists of a cluster of about 10 monoclinic needlelike Pseudobrookite crystals. These crystals range in length from 0.1 - 0.8" (0.3 -2.0 cm) and are in generally good condition, though I believe that at least 3 of them are damaged and incomplete. The crystals have good form, nonetheless, and are easy to see when viewed against a pale background. They have the standard black color and what appears to be a submetallic-to-adamantine luster, and are, of course, opaque. The cluster was somehow removed from a piece of host rock and glued into a small hole that was drilled into the small face of a cork. The cork was then pushed into a small section of test tube that was shortened for the purpose. I have cleaned the glass tube, which was quite dirty, and replaced it over the specimen- the tube is rather old, and shows slight striations running down its sides that may interfere slightly with one's examination through it. These are the longest Pseudobrookite crystals that I have seen yet.
