I have five(use four) mini obelisks I keep at each side of my bedroom. As wll as polished stones. Be forewarned DO NOT Cleanse them in water!!!. the reason is that angelite is a water lacking calcite.When doing so ,it removes the polish and you have a rough stone and brittle as well. a little water splashed on it won`t damage it, but washing it thoroughly in a sink is another matter altogether. Years ago i did use this stone in a healing elixir. helped with a cold. The polish was worn away from it. i survived and Melody's book says it is safe as well. for some reason someone said it wasn`t safe.

anyhow for cleansing this without water, one method which i use is you put it out in sunlight and let the sun's energy cleanse it for at least a few hours. Also another method is to place it on a quartz crystal cluster.And in the second method the longer the better. still a third method was to cleanse it on a bed of sea salt

Used for healing infectious diseases, headaches, hemoglobin deficiencies, throat inflammations and infections, thymus, heart function, and circulatory system.
