Black Onyx Pentacle Pendulum

This pendulum measures 11" long. It has black onyx and the pentacle measures 1" wide.I tried to take several pictures of it, and this picture was taken in full thunderstorm, and it came out with a red halo.. no matter what i did, the red tinge stayed..so i believe this pendulum is very powerful. The pendulum is activated and ready to go.  $3.50 shipping.
