Polished Hematite spheres are a great tool for grounding and centering. Hematite is the crystal form of iron, so when held in the hand you feel its natural density. It is also wonderful for grounding and centering meditations because it is linked to the root chakra. It's no surprise that this stone is associated with the astrological sign of Capricorn the Cardinal earth sign that begins Winter. This is some serious Earth centered energy!
