Here is a superb, large cluster of faden quartz crystals with sharply defined white lines running up the middle of every tabular, water clear quartz crystal in the group. The crystals in the cluster are flat and tabular, and are double-terminated. The white line zones stand out nicely against the clear, gemmy quartz that makes up the majority of the crystals. The white lines are strings of air bubbles which formed when the crystals were growing, as they continually broke and re-formed when the fissure they grew in expanded. There is no damage.
