Maintenance method of crystal:
1, the maintenance method of crystal is the same as that of ordinary gemstones, so be careful not to put it together with other ornaments to avoid collision and scratch;
2. Because the crystal surface is as bright as a mirror, it will be stained with sweat and grease and lose its luster. It is recommended to wipe with a soft cloth after each wear.
3. When soaking in hot springs, doing housework, making up, and swimming, the crystal should be taken out, because water and chemicals will adhere to the surface of the crystal, making the crystal dim;
4. Although the hardness of rock crystals is relatively high, they may be damaged when they hit hard objects, fall or collide with each other. Therefore, care should be taken to avoid scratching. When wiping dust, the strength should also be light to avoid scattering crystals by particles on the surface.
Crystal is a rare mineral, a kind of gem, and a timely crystal, which belongs to the timely family in mineralogy. The main chemical composition is silicon dioxide, and the chemical formula is SiO2.
When pure, colorless and transparent crystals are formed. When containing trace elements such as aluminum and iron, it is pink, purple, yellow and brown. After irradiation, trace elements form different types of color centers and produce different colors, such as purple, yellow, brown and pink. Minerals containing associated inclusions are called inclusion crystals, such as hair crystal, green ghost, red rabbit hair and so on. Inclusions include rutile, tourmaline, actinolite, mica and chlorite.
