Off of the top of your head, which crystals might come to mind regarding the topic of Ancient Mystery Schools and the accessing of past info?
This was the very question that I posed to a dear friend of mine by the name of Crystalmoon. What follows is based on her reply.
Record Keeper Quartz
The Record Keeper Quartz is recognized by a raised (or several raised) perfect triangle(s) located on one or more of the crystal faces. It should be noted that the quartz crystal is not the only crystal which is a record keeper.
The record keeper is a crystal within which wisdom is stored. When one properly attunes to this crystal, the ancient knowledge and profound secrets of the universe can be psychically retrieved. These crystals have been consciously and purposely programmed by the beings who created the energies which have culminated in the actualization of life on this plane, and by their direct descendants (eg. the Atlanteans and Lemurians).
The purposes of accessing information from the record keeper are
• to provide one with the information concerning the origin of the human race, the human soul, and all that exists or has existed in one's reality;Only those with open minds and pure hearts can access the information via attunement of the consciousness with the inner energies of the crystal.
The information provided by the record keeper enhances one's light, provides for a deeper access to personal wisdom, and promotes a greater peace to be used in this world.
The "three" of the triangle(s) located upon the face(s) of the crystal represents perfect balance achieved when the physical, mental, and emotional aspects of one's being is aligned with the love and purity of the highest spirituality. The triangular shape, of the "doors" which lead to the records, also symbolizes the third-eye, the creation, and the preservation of the state of perfection which serves as a pathway toward the enlightened state.The information stored within the record keeper could be relevant or non-relevant to physical life on Earth. One must be open and willing to accept all information (even those concepts which one would judge as inconceivable) and mus be capable (as we all are) of processing the information and applying it to this physical life.
The record keeper crystal is usually a personal meditation crystal. Meditation with the crystal is easily accomplished by placing a triangle upon the third-eye. Subsequent to this placement, close the eyes, still and open the mind, initiate circular breathing, relax, and be prepared to receive the information
Another method of assessing information is to activate the triangle by rubbing the thumbnail across the triangle from top to bottom. This provides the opening. Closing-off the source is accomplished by the opposite manipulation.
If one is meant to experience a record keeper, the universe will provide. The record keeper which "comes" to you contains the information which will be beneficial to your personal development and/or will provide information which will assist you in helping another.

Petrified Wood
Petrified wood provides strength in all areas of one's life. It is also a good stone for grounding. It provides access to, and explicit information concerning, past-lives; this action is furthered via meditation with the stone.
Petrified wood is also a "stone of transformation", assisting one to advance to one's highest chosen level, to commence ascension to a higher aspect of the self, and to recognize that no action unnecessary - but that all actions bring one to one's ultimate purpose.
