Faden crystals- have a distinct white, milky line that runs through the middle of them. It is formed when there has been a fracture in them and have regrown. These fractures may have been caused through earthquakes or other shifts in the earth’s core. A great stone for healing the etheric bodies and auric field. Excellent crystal to help in the mending of bones, tears in muscles etc. to me it symbolises a crystal of strength due to it’s own ability to mend under such intense conditions. A powerful ally to have on all levels of healing.
