This thumbnail specimen consists of a shapeless chunk of crystalline Eudialyte. The piece shows no evidence of a definite crystal form- all faces and edges are uneven and exist due to breakage. It has a deep red-brown coloration and a pearly luster, and is only dimly translucent, though a few spots show noticeable transparence. There is no host rock of any sort present, and it is affixed inside a plastic specimen box with an adhesive putty.
