The female termination tip looks like a small pyramid, because this wand was cut to mimic the proportions of the Great Pyramid at Giza, which is thought to be a mammoth antenna and amplifier for Universal Life Force Energy.
This wand is made of laboratory quartz, so it is extremely pure energetically, and is the perfect instrument for those who would like to program their Vogel wand in accordance with their own spiritual practice.
“The crystal is a neutral object whose inner structure exhibits a state of perfection and balance,” according to crystal researcher Marcel Vogel, a senior scientist with IBM for 27 years. “When it's cut to the proper form and when the human mind enters into relationship with its structural perfection, the crystal emits a vibration which extends and amplifies the powers of the human mind. Like a laser, it radiates energy in a coherent, highly concentrated form, and this energy may be transmitted into objects or people at will.”
Vogel believed that the most important thing to remember in working with faceted crystals for healing is that the purpose of the faceting should be to amplify and transmit an increasingly coherent stream of energy to a subject.
Some hexagonal quartz crystal wands occur naturally with six more or less equilateral sides and more or less equal triangular termination facets. Energy healers discovered that these six sided wands amplifed the energy being transmitted by the wand when the termination facets on the female end created a more obtuse angle and when the termination facets on the male end created a more acute angle. 
In a naturally formed quartz crystal of somewhat irregular shape and symmetry, the energy within the crystal tends to move through the crystal in a less directed way than the Vogel style cuts. But when a crystal had a very definite symmetry, especially the hexagonal symmetry, then the energy gathers in the larger, receptive end of the crystal, and if directed by a knowledgeable human hand, travels in a series of tighter and tighter concentric circles around the interior of the crystal, and down into the tip of the male end of the crystal, where it would be emitted as a much more coherent stream of energy. 
Energy healers also discovered that when the sharp male tip of the healing wand is congruent with the C-axis of the crystal, exactly centered within the circle formed when you look head-on at the male end of the crystal, this made the energetic flow stronger and more coherent.

Total symmetry created the crystal healer's version of the laser beam.
Marcel Vogel's healing wands were refined artistic versions of this well-known type of hexagonal natural healing wand, known for millennia to energy healers worldwide.
According to Marcel Vogel's written specifications for Vogel healing wands, good Vogel wands should have precisely equal facets on the shaft and tips; good clarity, preferably 90% or more; a well-defined C-axis that runs parallel to the shaft; and termination tips centered in the very middle of the shaft. The male and female terminations should be sharp, and the male should be more acute than the female. The female termination should be larger than the male tip. 
The male termination tip of this gorgeous Vogel healing wand is fashioned to form an extremely sharp tip designed to maximize the coherence and strength of energy streaming from the wand, while the female termination tip was cut a little wider, to maximize the area available for input of Universal Life Force energy from Source, and particularly from the palm chakra of the crystal healing practitioner.
As the prana spirals down the shaft of the wand, the energy stream is amplifed every time it encounters a facet on the shaft. The super-charged energy stream coalesces at the male end of the wand, and is emitted as a highly coherent laser-like beam for use in meditation, vibrational healing and subtle communications.
Energy and crystal healers prize Vogel cut quartz crystals to this day. The art of cutting crystals for use in healing requires extensive knowledge of the high art of crystal-cutting and polishing, an intuitive feel for the subtle energies involved, and an awareness of the needs of the energy healer who will be using the wand.
In his early experiments with cutting healing crystals, which he conducted for many years, Marcel Vogel saw the Kabbalistic Tree of Life in a dream, which is shaped very much like four sided crystal wand with double termination tips.  He created his first 4-sided healing wands in that shape, and told the story of their origin in the crystal healing workshops he gave students around the world.
