This stone has grounding and healing properties. It is heavy, solid and silvery black. To the ancients, "hematite" was not what we currently call hematite, but instead what we have come to call bloodstone -- so all ancient referrals to hematite actually refer to bloodstone.
Hematite possesses the curious property of healing itself. Hematite is known as a "stone for the mind". It brings mental organization and is very grounding and calming. It helps with original thinking, logical thinking, and mathematics. It decreases negativity and can help balance the body/mind/spirit. When in the presence of a myriad of crystals with fluctuating and unwanted energetic effect, this stone will help ground you and neutralize any negative effects being perceived.
Hematite is exceptionally good at grounding out excess energy and acting as a stabilizing force. Many people use Hematite as a basis for other stones and crystals, or in cleansing/purifying activities in regard to other stones and crystals. Hematite helps to absorb negative energy and calms you in times of stress or worry. Hematite is a very protective stone, and is great to carry to help you stay grounded in many situations.
