The natural crystal growth environment is mostly hidden under the ground and in the cave. It needs a rich source of groundwater. The groundwater contains more saturated silica, and the pressure in this area is about twice to three under atmospheric pressure. At about 5%, the temperature needs to be between 550-600 °C. They experience more than 80 million years of growth time in the ground. The crystal will crystallize into hexagonal column crystal according to the natural law of "hexagonal crystal system". There are many crystal grains without chaos, and all the crystal tips point to the center of the hole and grow regularly.
In the ideal environment of artificial control, that is, the physical and chemical conditions meet the above conditions, the growth rate of crystal is about 0.8 mm per day (mm), which is also the standard production speed of many artificial crystal laboratories and factories. The crystal thus cultivated is the so-called "Synthetic Quartz", also known as "Cultivated Quartz" (CulturedQuartz). Artificial crystals are often cut into chips for use in the electronics, computer, and communications industries. The artificial crystal for general industrial use has a thickness of about 3 cm and takes about 40 days to grow. If it is to be used as a crystal ball for grinding 10 cm (100 mm) or more in the jewelry industry, in the most ideal environment. It usually takes about 120 to 180 days. In nature, the situation is not so optimistic, the conditions of raw materials, water quality, temperature, pressure, etc. have been changing, it is difficult to achieve the ideal situation, usually tens of thousands of times, or millions of times, in order to achieve the same growth . This is also why the “geological age†is calculated based on “millions of years†and is also the precious part of “natural crystalâ€.
