The difference between natural crystal and quartzNatural crystal belongs to a crystalline mineral of quartz. The main component is silica. It is classified in different colors due to various impurities in quartz. However, natural crystal belongs to quartz, but there are still some differences between them.
Quartz is a mineral resource with very stable physical and chemical properties. The crystal belongs to the oxide mineral of cubic system, that is, low-temperature quartz (a-quartz), which is the most widely dispersed mineral in the quartz family. The generalized quartz also includes high temperature quartz (b-quartz). Quartz block, also known as silica, is not only the raw material for producing quartz sand (also known as silica sand), but also the raw material for quartz refractory materials and firing ferrosilicon.
Natural crystal is a colorless and transparent quartz crystal mineral. Its important chemistry is silica, which is a kind of material from the same womb as ordinary sand. When the silica crystal is perfect, it is crystal; after the silica is dehydrated, it is agate; after the silica aqueous body solidifies, it becomes opal; when the silica grain is less than a few microns, it forms chalcedony, flint and secondary quartzite.
The most 60% component of natural crystal is io2. The color of crystal is caused by various trace metals in addition to SiO2. In the natural environment, most crystals are "symbiotic" with minerals such as calcite, pyrite, pyroxene, mica sheets of various colors, Bessie, peat rock and rutile, forming some suspicious and illusory scenes, namely "heteromorphic crystals", which increases the fun and value of collecting crystals. Most crystals grow underground. The growth process requires a large number of underground water sources containing saturated sand dioxide. The temperature is between 550-600c and the pressure is twice to three times greater than the atmospheric pressure. After a long time, they become hexagonal columnar crystals
Quartz is a kind of mineral that is easy to become liquid under heat or pressure. It is also a very common rock forming mineral, which is found in all three types of rocks. Because it crystallizes last in igneous rocks, it usually lacks a complete crystal plane and is mostly filled in the middle of other pre crystallized rock forming minerals. The composition of quartz is the simplest SiO2, glass luster, no cleavage surface, but with shell fracture. Microcrystalline quartz is called chalcedony, agate or Jasper. Pure quartz is colorless, but it often presents different colors due to impurities containing transition elements. Quartz is stable and not easily weathered or todayhoth changes to other minerals.
3 quartz stone is generally 15 thick, and crystal stone is only 12 thick. In addition, crystal stone has high resin content and poor hardness. It looks crystal clear and transparent. There may be glass fragments in quartz stone, but it will not be crystal clear! Quartz stone is heavier than crystal stone. Quartz stone is much stronger than crystal stone in high temperature resistance. Crystal belongs to pure quartz, so quartz also has the same effect. Only valuable gem grade quartz can be called crystal, and there is room for appreciation and appreciation.
