Distinguished by raised triangle shaped markings on one or more of the crystals faces. The "recorders" (as the markings on these crystals are referred to) may look like a raised area on the face, but if you run your hand over it, you cannot usually feel them at all. This is why record keepers often go unnoticed, and will sometimes only reveal themselves when they come into the hands of the person they are meant for. If you want to look for a recorder on a crystal, you should hold the face to the light, and turn it slowly, observing all angles. Look very carefully and you may just find a hidden secret! It is believed that the Record Keeper is one of the most sacred crystals because it holds the wisdom and knowledge of the universe. To use a recorder crystal, meditate with it, opening your mind to receiving. Sometimes what you receive from these crystals may not even be consciously known to you. An excellent crystal to keep it under your pillow whilst asleep, so it can fill your dreams with wisdom and knowledge.
