With the constant change of concentration and composition, the solution is saturated or supersaturated. In a certain structural space (crystal hole) and under suitable thermodynamic conditions, silicon dioxide spontaneously generates crystal buds in solution. Or germinate under certain surrounding rock conditions. Generally speaking, the slower the lava cools and solidifies, the larger the crystal is.
Scientific basis and principle of crystal-It has been scientifically proved that rock crystals are piezoelectric, and they can release 8 million seismic waves every second on average, which contains powerful and rich energy. Moreover, the rock crystal has experienced the essence of the earth for more than 10 million years, interacting with the vibration of nature for a long time, and its positive magnetic field hides huge and infinite energy waves. For us who have been exposed to negative magnetic field for a long time, wearing crystal helps to transform our energy frequency into a stronger positive magnetic field and release it, thus affecting our daily life, making friends at work or academic performance.
Crystal is a very stable physical and chemical substance. Its piezoelectric characteristics and strong elasticity make its mechanical vibration show excellent frequency characteristics such as high Q value, low mobility, high sensitivity and high stability. Therefore, all oscillators and filters that require high precision and stable frequency must use crystals as oscillation materials. Its uses, such as frequency synthesis, counting, navigation, guidance, fax, computer, communication, timing and so on, are even more important.
The main element of Crystal Rock Crystal Shi Ying is silica (timely). We usually call it transparent crystal, but they are the same element. The corresponding chemical composition is silicon dioxide SiO2, which belongs to hexagonal system. Its hardness is Mohs 7, its specific gravity is 2.66, its refractive index is 1.54- 1.55, its birefringence is 0.0009, and it has glass luster (glass has no refractive index). The common response time is mostly huge, but occasionally there are good transparent crystals. All kinds of crystals contain different trace metals, which makes them have their own unique colors. Amethyst contains a little iron, topaz contains a little gold sandstone, and powder crystal contains a little titanium. And SiO2 (silicon dioxide) is generally divided into two types-low temperature response and high temperature response. The growth temperature of crystals is about 550-600℃, and the crystals generated between 550-573℃ belong to low temperature strain. Common crystals belong to this category, and their clusters are hexagonal cylinders (hexagonal crystal system). The temperature between 573-600°C belongs to high temperature response, and agate is a common high temperature response.

crystal
Basically, the most important component of crystal is "silicon dioxide", which is also the most important mineral, occupying more than 65% of the crust components. It also contains various trace metals, so it will cause crystals of different colors; Moreover, crystals are widely associated with various minerals in nature, such as mica, feldspar, calcite, tourmaline, rutile, granite and so on.
The growth environment of crystals is mostly underground and caves, which requires rich underground water sources, and groundwater mostly contains saturated silicon dioxide. At the same time, the pressure inside it needs to be about two to three times that of atmospheric pressure, and the temperature needs to be between 550 and 600℃. If given a proper time, the crystal will crystallize into hexagonal columnar crystals according to the natural law of hexagonal crystal system.
Usually, in the ideal environment controlled by human beings, that is, when the physical and chemical conditions meet the above conditions, the growth rate of crystals is about 0.8 mm per day. This is also the standard production speed of many intraocular lenses in laboratories and factories. The crystal thus cultivated is the so-called "synthetic Shi Ying", which is usually cut into chips and used in electronics, computer and communication industries. Some people call it "breeding Shi Ying". Although they use different words, they actually mean the same thing. Generally, the thickness of industrial intraocular lens is about 3 cm, that is, 30mm, and it takes about 40 days to grow. It generally takes about180 days for jewelry industry to grind a crystal ball with a size above 10 cm (100mm). However, this speed is only possible in the most ideal environment controlled by human beings. In nature, the situation is not so optimistic because of raw materials, water quality, temperature, pressure and other conditions. Are constantly 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 the reason why the "geological age" movement takes "million years" as the calculation base, and it is also the precious place of "crystal rock".
When a normal crystal is growing, people often find that the growth line is parallel to the cylindrical tip line. Because of the small growth space in underground and caves, especially in the event of earthquakes or crustal changes, they are even easily squeezed by other minerals, and different "crystal planes" often appear. Also, when crystals are still in liquid state, they are often wrapped by other minerals and marls and grow together, such as rutile (which will become crystals later), volcanic marls (which will become phantom crystals later) and so on. These are "part of nature", please don't treat them as "flaws".
