This is a Pat Flanagan “Experimental Sensor II” From 1976. At first glance psychedelic Fibonacci spiral and Egyptian hieroglyphics makes this strange piece of jewelry feel as thought it is the key to time travel or eternal life. In fact Dr. Flanagan wrote the book on pyramid power and claimed these pendants have the ability to produce the same energetic effects as pyramids, but in a more compact form.
