Bloodstones are considered great purifiers and are strenghtening for the auric field working through the root and heart chakras. Physically they can stimulate the liver and fortify the blood at the bone marrow level. They have also been used in times past to instill courage and endurance on the battlefield and so are assumed to pass those abilities easily into our modern day lives, giving us the strength to stand up for ourselves at work or social situations. Many consider bloodstone to be a stone of protection against evil in general, I believe, because of how it helps fortify the aura and dispel negativity. Current stock is mostly dark greens with little red showing.
