This small thumbnail specimen consists of a single tetragonal prismatic Xenotime crystal. This crystal shows only minor damage and has excellent form, with well-defined edges and clean faces that possess a bright pearly-to-vitreous luster. Its color is a moderately deep brown with golden highlights, and it is translucent to dimly transparent around its edges. However, there are patches of the surface material that are noticeably transparent a few millimeters down into the crystal. This transparence allows one to see a few rutile needles that permeate the crystal in different areas. There is no host rock present on this piece.
