Most of the crystals are under the ground and in the cave. There is a rich source of groundwater, and the groundwater contains saturated silica. At the same time, the pressure in this way needs to be about twice to three times under the atmospheric pressure. The temperature needs to be at the temperature. Between 550-600 ° C, if the appropriate time is given, the crystal will be crystal into six -square cylindrical crystals according to the natural rules of "Hexagonal System".
Generally, in the ideal environment of artificial control, under the condition of physical and chemical conditions that meet the above conditions, the growth rate of the crystal is about 0.8 mm (mm) per day. This is also the standard production speed of many artificial crystal laboratories and factories. The crystal cultivation is the so -called "Synthetic Quartz", which is usually cut into chips (Chips) for electronics, computers, and communication industries; some people call it "Cultivated Quartz, Cultudured Quatrtz), although using different terms, actually talks about the same thing. Generally, the thickness of the artificial crystal of industrial use requires about three centimeters, that is, 30mm, it takes about 40 days to grow; if it is used for the jewelry industry to grind it into a crystal ball of more than ten centimeters (100mm), It takes 120 to 180 days. However, this is the most ideal environment under artificial control. It is possible to have this speed. In nature, the situation is not so optimistic, because the conditions of raw materials, water quality, temperature, pressure, etc. have been changing. It is difficult to reach the ideal situation, usually tens of thousands of times or millions of times to achieve the same growth. This is why the "Geological Age" moves with "Millions of Years" as the calculation base, and it is also the reason why "Natural Crystal" is precious.
When the normal crystal grows, it can be found that the Growth Lines parallel to the pillar -shaped tip edges. Due to the narrow growth space in the ground and the cave, especially when encountering an earthquake, or when the crust changes, it is even easy to be squeezed by other ore, which often compresses different "crystal surfaces". In addition, when the crystal is still liquid, other ore, mud and gray crystals are often covered, such as golden stones (later turned into hair crystals), volcanic mud (later become a phantom crystal) and many more. All these are "part of nature", please don't be regarded as "flaws."
