Glowing Jade

05th November 2019

Jade is exploited since 7000 years but it is only during the XIXth century that we differentiate the two types of Jade: Jadeite and Nephrite. It is difficult to distinguish them, but they are different for their composition, hardness, structure, and rarity.

In Chinese culture, jade is a symbol of loyalty and wisdom. It is believed that this stone helps to conserve the body of the dead, which is why we usually find them in graves.

Jadeite is mainly found in sources located in Burma, Russia & USA, but not in China. It is composed of sodium, aluminum and silicate and has a hardness of 7 on Mohs scale.

It is commonly of pale green color but it exists in all colors of the spectrum. The most valuable specie is the Imperial Jadeite that presents an intense and homogenous green color with a translucent body. Indeed, jadeite can be opaque to semi transparent and can have a certain glow that increases its desirability.


Jadeite is most of time certified by gemological laboratories to indicate their typology. The typology is graded depending on the treatments the stone endured:

Type A : non treated stone, 100% natural à highest value.

Type B: indication of bleaching which improves the color by reducing brown hues. Indication of impregnation with polymers which improves clarity and transparency.

Type C: indication of dyeing which improves the color.

Nephrite is more common than Jadeite, its main deposits are in China, Burma, Brazil, Canada and Australia. It has a slightly different composition as it is constituted of calcium, magnesium, iron and silicate. It also has a lower hardness compared to Jadeite: 6 on Mohs Scale.

On the contrary of jadeite, nephrite is mostly presenting a white, dark green or black body color, with a lower translucency and a more opaque luster. Nephrite doesn’t have any type of grades.
