This small hand specimen is the most impressive Eudialyte piece that I have yet seen! It consists of a chunk of nepheline-bearing pegmatite in which rest four crystals, three of which show only a small amount of damage and are essentially complete. They have a distorted rhombohedral form that reminds me of orthoclase crystals. Their edges, though rounded, are still quite evident, and their faces are relatively flat and have a waxy-to-pearly luster. Their color is a moderate red with a hint of violet, and they appear to be completely opaque, though this may be mostly due to their intense internal fracturing. The most incomplete crystal shows a very uneven breakage surface. There are some thin, black needlelike crystals among the Eudialytes, but I do not know exactly what they are. From what I have heard, crystals of this mineral are rather difficult to find.
