Pendulums have been used as divination tools for a very long time. Dowsing was practiced by many cultures all throughout history including the Chinese, Greeks, and Egyptians to name a few. We decided to make our own Tetragrammaton Pendulum. The double-sided tetragrammaton medallion measures approximately 1.375 inches in diameter, the chain 7.5 inches, and the pendulum itself 1.5 inches tall by 1 inch wide and has a nice weight to it. We cast these using the finest, lead-free pewter. Made in the USA.
