Appearance Characteristics Of Quartz Stone

The composition of quartz is the simplest silica, with a glassy luster and no cleavage planes, but with shell like fracture surfaces. Microcrystalline quartz is called chalcedony, agate, or jasper. Pure quartz is colorless, but it presents different colors due to impurities that often contain transition elements. Quartz is very stable and not easily weathered or transformed into other minerals. According to the degree of SiO2 crystallization, it can be divided into crystalline single crystal quartz and polycrystalline quartzite jade. Gloss: Glass luster. Color: None, white, with shades of gray, yellow to orange yellow, purple, deep purple, pink, gray brown, brown, black. Stripe: White. Specific gravity: 2.65~2.66. Category: Metamorphic rock, formed by metamorphism of sandstone. When crystals contain a large number of parallel arranged fibrous inclusions, their curved gemstone surfaces can exhibit the cat's eye effect. Generally, quartz has a higher cat's eye curve, and the fibrous inclusions are clearly visible.
Formation process:
During the process of magma intrusion and evolution, due to changes in temperature, pressure, and other conditions, hydrothermal fluids rich in SiO2 are differentiated, which penetrate into the metamorphic rock series of the surrounding rock along bedding and fractures, or invade along the contact fracture zone of the early magmatic rock, forming vein like quartzite ore bodies.
Material classification:
Quartz types: pink quartz, green quartz, white quartz, yellow quartz.
Quartz raw materials can be divided into ordinary quartz sand, refined quartz sand, high-purity quartz sand, fused silica sand, and silica micropowder.
