Left and Right-hand activation crystals can be recognized by the presence of an additional face, similar to a time-link or window crystal. In the case of the right/left hand activation crystal, these faces are referred to as x-faces and are a less common crystal facet that appears in the upper left or right corner of the long, m-faces or “sides “of some quartz crystals.
Dauphine twins and Brazil Law twins can also be recognized by presence and positioning of this rare quartz face.
For the esoterically minded, the x-face denotes either right or left-handed activation in a crystal. Some also maintain that the crystal is either masculine or feminine in polarity, according to the placement of the x-faces.
When attempting to understand how or why a crystal should be right or left-handed in nature, it may help to envision the quartz formation from a molecular perspective. The term right or left-handed refers to the directional growth of the quartz crystal, and would be more correctly stated not as "left or right-handed" per se, but rather as the growth of the crystal tending in either a clockwise or counter-clockwise spiral. During the formative process of macromosaic quartz, as elements swirl in the hot liquid matrix and silica dioxide (quartz) is created, it forms simple units known as “crystallites”.
In the bonding of these units the molecules will begin to move in one of two directions as they form. Envision, if you will, the molecular structuring of the quartz proceeding in a spiral, as particle upon particle is transferred and crystallization takes place. In this way we can begin to fathom the directional tendency of its formation and hence, its energetic signature as either left or right, clockwise or counterclockwise, masculine or feminine. This aspect of polarity exists in all quartz crystals as the original string of crystallites will form along the crystals c-axis and will always tend to spiral in either one direction or the other. Indication of polarity can be very useful in determining the application of the crystal in healing practice.
Through contemplation of these spiraling polar opposites one may obtain a clear picture of the function of the right or left-handed activation crystal. To say that left is feminine and right masculine is a simplistic way to begin this contemplation though the concept of actual gender or sex can also tend to be misleading.
It is rare to find clear signs of left or right handedness on the surface of the crystals and these signatures are often sought after by collectors of unusual quartz or rare formations.
We may also make use of right or left-handed quartz crystals in healing practice, invoking archetypal powers of one of countless specific aspects of either masculinity or femininity and applying this vibrational frequency to balance any discordant vibrations in ourselves or our surroundings.
Many quartz crystals have visible areas of previous contact with other crystals. Because the other individual crystals in the family grew so close, and the crystals were not on a parallel growth path, the quartz formed in such a way as to compensate for the other's presence in the ordering of molecules.
It may help to picture the way that a tree growing right next to a chain-link fence will, in time, envelope parts of the fence as it grows. In resting one’s finger or thumb on the contact impression of a quartz crystal one may note that the digit enters below the “surface barrier” of the crystal rather than merely resting on the flat face of the stone.
This point of contact is an ideal way to enter and exchange with the vibrational frequency of the quartz crystal in a way with which it was formerly accustomed. The crystal actually compensated in molecular structuring and formed specifically in order to have an exterior member present in that area.
At a glance, this apparent mineral inclusion appears to be calcite, judging by its silvery-whitish color and rhomboid form. Upon closer inspection, however, one may perceive that there is a small opening on the quartz surface, indicating that it is actually a hollow rhombohedral cavity with traces of a reddish clay-like material near the opening.
This type of cavity is known as an "inclusion void" and the example shown in the photo is the natural cast of a calcite mineral that dissolved away during the formative phase of the crystal, leaving a perfect impression of itself inside the optically clear quartz. Often an inclusion void may be entirely enclosed within the quartz host, making positive identification difficult.
Whether an actual mineral inclusion exists within the cavity, or if it is merely an empty void in the form of the mineral that was formerly present, may be difficult to determine. In this particular case the mineral cast is near to the surface of the quartz crystal and the opening to the hollow interior is visible, a clear indication of an inclusion void.
