The value of jadeite and jade depends largely on the material, color, texture, cutting, size, transparency and historical background. Generally speaking, high-quality jadeite and jade are precious.

However, in the current market, the price of good quality jade is often higher than that of the same quality jade. An important reason is that jade has a high status and important symbolic significance in the history and culture of China, so it has always been the first choice of many people in China. Moreover, it has been sought after and enthusiastically sought after by many people in China, further pushing up the price of jade.

Jade is the general name of natural jade, and it is a mineral aggregate. "Jade" is broad, including Hetian jade, emerald, foam jade, jadeite, dushan jade, Huang Longyu, bloodstone and agate. And "emerald" is a kind of jade. The concepts of jadeite and jade are like "tea" and "Tieguanyin". The word "tea" has a wide range, including: Tieguanyin, Longjing, jasmine tea, chrysanthemum tea, etc., and "Tieguanyin" only refers to Tieguanyin in Changchun.

Jadeite is a mineral aggregate mainly composed of jadeite, which has six obvious characteristics, such as diverse colors, strong luster, high refractive index, heavy specific gravity, high hardness and stable physical properties, which are all advantages that other jadeites do not have. Therefore, jade has the reputation of "the king of jade" and is internationally recognized as a gem-grade jade. However, the origin of gem-grade jadeite is Myanmar, so the uniqueness of the origin also determines its nobility.

Formation of jadeite

Jadeite is a dense and massive aggregate formed by countless fine fibrous mineral crystallites, mainly jadeite. There are several reasons for its formation: the desilication product of residual granite slurry that magma invaded ultrabasic rocks under high pressure. Primary albite is decomposed into jadeite during regional metamorphism. Or that albite first formed glaucophane schist with low metamorphic degree and then further metamorphic jadeite under the action of compressive and torsional stress and low temperature caused by plate collision.

Granite dikes and light gabbro dikes were metasomatized under the pressure of 12- 14kPa under the action of hot water solution with high sodium potential. According to the discovery of three-phase inclusions of water, methane and jadeite in jadeite rocks, it is considered that jadeite is crystallized from the silicate melt of jadeite and comes from the alkali-containing pyroxene layer widely existing in the mantle of 300-400km.
