Hemetite flesh plugs. Hematite is an unusual shiny black stone with a high polish. It looks almost metallic. These are double flared plugs. The name hemetite comes from the Latin meaning 'blood stone', it's made mostly from Iron and when it is found in its natural state it is usually coloured red by rust. Our blood of course also contains a large amout of Iron. It's an earthy stone said to be grounding and good for dispelling negative energy.
