1. What are gems and jade? Gems are broadly the most beautiful and rare in the stone. It consists of two major categories of gemstones and jade. Narrow gemstones are single-crystal minerals that are naturally produced (such as natural gold, diamond) or compounds (such as crystal, red and blue). Jade refers to a polycrystalline rock composed of a single mineral or a multi-mineral aggregate. Second, what is jade? Jade has the reputation of the king of jade. It is a jadeite in jade. Its chemical composition is sodium aluminosilicate. The mineral composition is a pyroxene-based pyroxene. The structure is composed of numerous fine fibrous microcrystals. A dense block assembly having a carpet-like structure. It is very tough, resistant to high impact forces and pressures, and its products are durable. Jadeite has a hardness of 6.5-7 Moss, a specific gravity of 3.3, a glass luster or a pearl luster, and is often translucent, and a few are transparent (fully transparent "glass"), and the fracture is staggered. In China's gemstones, there is a saying that Huang Wei is green and green is green. The origin of the jadeite is mainly concentrated in the Archaeological Area of ​​Myitkyina in northern Myanmar. Third, what is Hetian jade? Hetian jade refers to the oldest nephrite produced in Hetian, Xinjiang. Its chemical composition is calcium magnesium silicate, and its mineral composition is a special aggregate composed of hornblende. Mohs hardness 6-6.5, specific gravity 2.9-3.1, fracture staggered, grease luster, translucent to opaque, color is white, cyan, yellow, black, red, etc., the color of a piece of material is generally uniform, its chemistry The composition is relatively stable, can resist strong acid and alkali, and is generally used for making jade carvings and various small pendants and bracelets. It is also the main material of ancient jade products in China. Fourth, what is jade? The main producing area of ​​Daiyu is Xiuyan County, Liaoning Province, which is also produced in Xinyi, Sichuan and Sichuan Huili. The chemical composition of Saitama is a hydrated magnesium silicate. The mineral composition is a collection of snake and stone minerals. It is composed of fine fibrous and leaf-like serpentine crystals. It is a very delicate and dense block. . It is available in a variety of colors, which are uncommon in pale green and yellowish green. It has a hardness of 2.5-4.5, a specific gravity of about 2.5, grease luster or waxy luster; translucent to opaque, and very few are transparent, similar to plexiglass. Due to its low hardness, Shaoyu is a low-grade jade material. It is often used as a jade carving and various small pendants. It also makes life products such as tea sets, wine sets, fitness balls and jade pillows. 5. What is Dushan jade? Dushan jade is named after Dushan, which is 8 kilometers northeast of Nanyang City, Henan Province. Its mineral composition is the eucalyptus petrified plagioclase, which is a multi-color jade. Its color is bright, the pattern is complete, the combination of light and shade, and the texture is delicate, dense and hard. Mohs hardness 6-6.5, specific gravity 2.9; glass luster or grease luster, opaque or micro-transparent. Dushan jade is commonly used in the market to make jade carvings of various ornaments.
