These Faceted Quartz Pendulums are very clear.  They are smaller than the pendulums I am used to seeing.  They would be perfect to take with you, if you are traveling or have limited space.
 
Quartz is an amplifier and can be programmed.  It will also enhance any crystals which are placed near the pendulum.
 
Available:  1, 2, 3, and 4.
