This specimen is mostly massive (or more properly granular) euxenite. It is black, opaque, and has a luster that varies from dull to submetalic. Under a loupe, individual grains may be examined, and these often have a high luster, even a silvery-black appearance. The euxenite is accompanied by a feldspar which is translucent and white, but has been stained brown, possibly by weathered euxenite.
