Merlin quartz crystal  (also called Generator) have six equally sized faces and a centrally located point.

It is very rare to find a natural crystal in such a precise configuration. You may find a point with the energetic qualities of a Merlin, but the physical description may not be textbook perfect.

Crystals are commonly polished into Merlin (Generator) points.

Merlin quartz crystal is very good for focusing energy (as in crystal wands). All the energy is coming out the center of the point and is very powerful.

They have a crisp, precise, very direct energy. Two good words to describe the energy of a Generator or Merlin quartz crystal are focus and precision.
