Quartzite jade: Quartzite jade is a compact block composed of granular timely aggregates, and the timely content is above 90%.

Jadeite: Jadeite, also known as jadeite, jadeite and Burmese jade, is a kind of jade. The correct definition of jadeite is fibrous aggregate composed of pyroxene minerals, mainly jadeite minerals. But jade is not equal to jade.

2, the composition is different

Quartzite jade: Except in time, it often contains chromite, sericite, lepidolite, hematite, glaucophane and other minerals. When it is pure, quartzite is white, with a hardness of 7, which is equivalent to jadeite, with a density of about 2.65 and a refractive index of about 1.54, and has a glass luster.

Jadeite: Jadeite is a stone polycrystalline aggregate that reaches the jade level under geological action. It is mainly composed of jadeite or jadeite, sodium (sodalite) and sodalite (omphacite), and may contain amphibole, feldspar, chromite and limonite.

3. Different places of origin

Quartzite jade: Beijing white jade is a dense quartzite with pure white color and delicate texture, which was named after it was discovered in Xishan area of Beijing in the 1960s. Later, similar white quartzite was found in Hunan and other places. In order to unify the name, some experts suggest using the name of "Crystal White Jade" to show the characteristics of the time, including white quartzite jade produced in various places.

She Taicui, a kind of jade produced in Inner Mongolia, began to be mined in 2007, and was officially named "She Taicui" by well-known experts in geology, stone and jewelry in China in 2008.

Miyu, named after its production in Mixian County, Henan Province, is also called "Mixian Jade", "Henan Jade" and "Henan Cuisine". The timely particles in Mishan jade are very fine, which is difficult to be recognized by the naked eye, so it is as fine as nephrite.

Emerald: Most of the high-quality jadeite in the jewelry market comes from the Quaternary and Tertiary conglomerate layered jadeite deposits in the Ulu River (River) valley in northern Myanmar.

They are mainly distributed in Kachin State in northern Myanmar, with a length of about 240 km from north to south and a width of 170 km from east to west. 187 1 year, several major mineral deposits were discovered in Lu Wu, Myanmar (also known as Wu Jia, Wulong and Lu Wu), among which four are the most famous, namely Dumao, Myanmar, Panmao and Nannaimao.
