Pendulums are amazing intuitive tools. Ever since my first Reiki attunement and chakra balancing training, I have been using pendulums practically every day and am fascinated with what you can do with them. I have a special pendulum for crystal healings and a gorgeous blue lace agate pendulum for private dowsing and communication with the Light. Although pendulums work perfectly well no matter what material they are made with, I am drawn to gemstone pendulums and believe the energy of the crystals make the experience even deeper and more spiritual. I am sure you could find here a pendulum that speaks to you.
Blessings and happy dowsing!
