Hematite is a Projective stone that is good for healing, grounding, and scrying.
For healing, hold it in your Projective hand while visualizing the healing of whatever ailment you're going after, then place the stone on the body directly over the affected area.
For Grounding you can wear or carry this stone.
For scrying, light a red candle and hold the Hematite so that the candle flame is reflected on it. Then gaze at that reflection and visualize your question. The answer will come to you.
Hope this helped some. Good luck and Blessings to you!
