Abstract : Tunnels observed in unetched quartz crystals showing a multitude of orientations in the crystal are described. They varied from a fraction of a micron up to about 2 microns in their diameters, and penetrated a few millimeters into the crystal. The diameter was constant along the whole length of a given tunnel. It is suggested that these tunnels as well as tunnels in quartz in general, were formed during the growth of the crystal. By this assumption etching only broadens existing tunnels, and so makes them observable optically.
