Quartzite jade is a dense block composed of granular timely aggregates, while jadeite, also known as jadeite and Burmese jade, is a kind of jade, mainly composed of jadeite minerals, but jadeite is not equal to jadeite.

2, the composition is different

Seasonal rocks contain more than 90% of the time. Besides the time, they often contain minerals such as chromite, sericite, lepidolite, hematite and glaucophane. Jadeite is a kind of 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 physical properties

Quartzite has a hardness of 7, a density of 2.65 and a refractive index of 1.54. The hardness of jadeite is similar to that of quartzite, but its refractive index is relatively high, which is 1.66.

Extended data:

Quartz stone pretends to be jade. Quartz stone becomes cheap jadeite after acid treatment and coloring. The internal structure of jadeite is very tight, and the hardness is 7.5 modulus, so there is no crystal in jadeite. After acid treatment, Hetian jade imitates quartzite, showing a spider web distribution. So there are many cheap three-color or even four-color jadeites on the market.
