Orgonite is made up of crystals and Copper wire encased in resin. It counteracts the effects of EMFs (Electromagnetic Field) on the body.  This would be a great pendulum to use for balancing Chakras and bodywork.
 
The elements in Orgonite clear and heal emotions to bring about a sense of peace and relaxation.  It improves the flow of energy and balance in a person’s body and their living spaces.  I believe this is due to how conductive the Copper metal is.  When everything flows and is in balance, mental clarity and focus improve.
 
When I worked in a crystal shop, I was pricing new merchandise that came in and working on the computer.  I had a really bad headache.  When I took out the Orgonite Pyramids that we had received in the order and place them near me on the table, my headache instantly disappeared.
 
Pentagrams are used for protection from evil spirits and used in rituals to invoke or banish spirits.  They are also used to represent the five elements of air, fire, water, earth, and spirit.  Pentagrams can also be associated with the union of opposites such as male and female.  In early Christianity, the pentagram represented the five wounds of Christ or the Star of Bethlehem which appeared in the sky when Jesus was born.  The Sumerians felt it represented the “vault of Heaven” which was the planets of Jupiter, Mars, Mercury, Saturn, and Venus
 
Available: 1, and 2.  The price is per pendulum.
