Diffraction patterns of various crystal morphologies mounted in a quartz capillary: (a) needle, (b) diamond, (c) flat long hexagonal and (d) flat short hexagonal. In all cases a long unit cell is evident with streaky reflections. This results in significant overlap of the reflections and data that are unusable for high-resolution diffraction studies.
