A chunk of semicrystalline Eudialyte makes up the bulk of this thumbnail specimen. Though a few crystalline tendencies are notable, no definite crystal form is evident. The Eudialyte has the classic deep red color with a hint of violet and a pearly-to-vitreous luster, and is translucent. A small amount of what appears to be a feldspar host rock is present, and the piece is affixed inside a plastic specimen box with an adhesive putty.
