This specimen consists of a few large, intergrown Neptunite crystals on a pale gray host rock. They are heavily weathered, and along with the intergrowth, are thus heavily warped and have only a small amount of discernable crystal form. Their color is a deep red-brown, and their luster is waxy to pearly at best. I find this piece rather interesting because it brings out the natural color of Neptunite, which is often too deep to be discerned in complete, well-formed crystals that have the usual vitreous luster.
