Crystal was born in this environment, it is really incredible. Do you know what a crystal is? Have you ever worn a crystal? You know something about crystal. However, do you know what kind of environment a crystal is formed in? If you don't know any of this, don't take a quick look.

In the underground, caves, the need for a rich source of groundwater, groundwater and more saturated with silica, while the pressure needs to be about two to three times the atmospheric pressure, the temperature needs to be 550-600 ℃, and then give the appropriate time, the crystal will be in accordance with the "three-way crystal system" (hexagonal system) of natural law, and crystallization into a hexagonal crystal.

Usually, in the ideal environment of human control, that is, the physical and chemical conditions are in line with the above conditions, the growth rate of crystal is about 0.8 millimeters (mm) per day. This is also the standard production speed of many artificial crystal laboratories and factories. This culture out of the crystal, is the so-called "artificial crystal" (synthetic quartz), usually cut into chips (chips) for electronic, computer, communication industry use; also known as the "crystal" (cultivated quartz, cultured quatrtz), although the use of different nouns, in fact, is about the same thing. In general, the thickness of artificial crystal for industrial use is about 3cm, I .e. 30mm, and it takes about 40 days to grow. If it is to be ground into a crystal ball of more than 10cm (100mm) for jewelry industry, it usually takes about 120-180 days. However, this is only possible in the most ideal environment under human control. In nature, the situation is not so optimistic, because the conditions of raw materials, water quality, temperature, pressure, etc. are always changing. It is difficult to achieve the ideal situation. It usually takes tens of thousands or millions of times to achieve the same growth. This is why the "geological age" movement to "million years" as the calculation base, but also "natural crystal" (natural crystal) is precious.

Normal crystal in the growth, can be found and columnar tip edge line parallel to the growth lines (growth lines). Due to the underground, cave in the growth space is narrow, especially in the face of earthquakes, or crustal changes, and even vulnerable to other ore extrusion, often oppressed to produce different "crystal plane 」. Also, when the crystal is still in the liquid state, it is often coated with other ores and marls to crystallize and grow together, such as rutile (which later becomes crystal), volcanic mud ash (which later becomes phantom crystal), and so on. All of these are "part of nature" and please do not regard them as "flaws 」.
