We love a heavy pendulum and these hematite pendulums fit the bill at around .21 ounces each. Most crystal pendulums tend to be around .10 oz. 

Hematite is a very grounding and balancing stone, rich in iron oxide, and often used to help connect one back to the body. Great for a dowser as being grounded is key to receiving accurate results. 

Clearing hematite crystals frequently is important as it is a crystal that absorbs negativity - of great value in many ways - and you need to keep up with removing it. Place your pendulum in a sunny windowsill when you think of it. With intention, send sound to hematite, using a singing bowl, drum, or other percussion instrument. Tune into the pendulum while doing this to sense when the clearing is finished.
