To be considered a “Vogel” a crystal must be made of natural quartz and be cut with the appropriate care, intent, and precision necessary to assure the Universal Life Force is attracted, amplified, and transmitted properly. Essentially the literature tells us that a properly cut crystal takes in energy at the receptive end, amplifies it as it circulates around inside, hitting the internal sides of the polished side facets as it revolves, and then is transmitted from the focal end.
The crystal must be natural quartz.
The crystal must be hand cut with the necessary intent, skill, and understanding of the crystal and its intended uses.
The crystal must be doubly terminated or cut and polished to this shape.
The crystal has to be cut completely aligned with the C axis of the quartz crystal.
The receptive (sometimes called female) end of the crystal must be faceted forming an internal angle of 51 degrees, 51 minutes, 51 seconds. This is the same angle as the angle of the sides of the Great Pyramid at Giza.
The crystal must have four or more side facets.
The transmitter (sometimes referred to as the male) end of the crystal must be faceted with a more acute internal angle than the receptive end.
What are Vogel Crystals used for?
Basically a Vogel crystal is cut to amplify, coalesce, and focus thoughts and energy that you wish to direct into your body/mind or that of another person. The design of the crystal allows for your thoughts and energy (and the pervasive Universal Life Force), to enter the crystal at the receptive end, be amplified and focused as it travels in a circular pattern through the crystal, and be transmitted like a laser beam from the focal end.
In this way they are used primarily for healing efforts, both for sending healing energy to the body and the spirit; meditation to focus the connections with spirit world beings; and in efforts to focus our Life Forces on accomplishing our goals and dreams with laser like focus.
There is little really written on the uses of particular Vogel designs, but here is a short summary of what is known. For crystals of other cuts, you will need to work with them to determine their specific applications. Marcel Vogel pointed out in his teachings that a large number of facets was not necessary and that a crystal with 13 sides was more than adequate for all uses. However, current cutters offer a wider choice.
4 sided crystals are for healing efforts aimed at the physical body
6 sided crystals are used for healing emotional ailments
8 sided crystals are used for dealing with severe emotional trauma
13 sided crystals are used in meditation to connect with past lives21 sided crystals are used to resolve family issues
24/8 sided crystals are used for spiritual rebirth
24/12 sided crystals are used in transformation efforts
