These Himalayan crystals are found at very high altitudes, usually relatively close to the surface, which is why it's possible to use only hand tools for extraction.
The lifespan and formative history of a quartz crystal can be difficult to gauge. The Himalayas are considered a “young” mountain range but these crystals form in pockets deep beneath the surface and remain contained while slowly rising upward with the formation of the mountains.
The crystal "pockets" were previously far below sea level and now arrive at nearly 5000 meters altitude. This process takes millions of years! Consider that the Himalayas formed over approximately 50 million years and the Himalayan tectonic land plate is currently shifting at an average of 1-2 cm per year.
The miracle is that on their journey to the surface they remained relatively untouched and intact in nature. The matrix where they form is enclosed in an pocket/fissure of extremely hot liquid matrix, but by the time they are unearthed, this liquid matrix is no longer an active part of the cavern and only clay and other iron-relative minerals are left surrounding the crystals. Many quartz crystals are still attached to a larger “cluster” or family of stones, the environment looks much like a giant muddy “geode”. Often the points are facing downward or to the side and they must be wiggled free from the clay.
Many Himalayan quartz crystals are still attached the matrix or are independent "floater crystals" with complete body and no point of attachment to the matrix. Other crystals have already broken free from the matrix when found. This is due to the earth's tectonic movement: earthquakes!
Because of the constant shifting and movement of the Earth and the long slow process of mountain building/moving, it is a fact of nature that were these crystals not found by the hand of man, they would be pushed out. Like the petals of a flower gone to seed, they would one day tumble down that mountain and make the long journey by foothills, and river to return to the sands of the sea and start the whole process over again. It is a magical moment to rescue them, so close to the surface and complete in their perfected form.
The Himalayas of India are lively and birthplace of many gifts of wisdom and treasure. In fact, the entirety of the Himalayas, spanning many countries has proven to be very active and therefore abundant in her offerings.
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.
