Egyptians engraved bloodstone to use in divination.
Its an all around great stone for healing.
It is seen as a stone of strength and sacredness.
It can be used to banish negative energy and clears any energy disturbances it touches, especially that of the spiritual/physical body.
It can both dispell obscurity and create clarity and cause obscurity and create illusion.
The Leyden Papyrus declared that "The world has no greater thing than bloodstone," it opens all doors for its owner, breaks down the walls of prisons and averts many disasters.
It has a lot of potential. Read everything you can find on it. It's a very versatile stone.
Have fun. It's an awesome stone.
