Polished Hematite tumbled spheres are a great tool for grounding and centering. Hematite is the crystal form of iron, so when held in the hand you feel the serious weight that it brings as a crystal of stability. Hematite is good for grounding and focus; one favorite use is actually to keep it in your work space to help you stay on task (add fluorite for added focus!). 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!
