Classification And Identification of Jadeite

Posted by slang on September 4, 2009

Many jewellers classify jadeite by texture into three categories:

1. Old-mine or lao keng jadeite
2. Comparatively old-mine or jiu keng jade
3.  New-mine or xin keng jadeite

The old-mine is considered as the best category with fine texture, excellent lustre and high translucency.

Experts identify the quality of jadeite by the following criteria:

1. Intensity of color
2. Purity or Zheng: a pure green with no traces of blue or yellow
3. Intensity or nong: the more intense the green the better
4. Brightness or yang: a fresh brightness free from shade or mist
5. Evenness or yun:an even distribution of green throughout the gemstone
6. Translucency: the more translucent, the more valuable it is re: the lustrous and transparent one being the best cateogry

When buying jadeite, the aforesaid criteria need to be scrutinized. Other ancillary matching jewel like diamonds which are occassionally used to enchance its being is really of secondary importance.

The Term “Jade”, Jadeite,Antique Jade,Nephrite

Posted by slang on

Jade is a very wide term for many colors of jade stones namely the white,grey,green(fresh) green, purple, yellow,brown,red,green-white and others.

Jadeite which is popularly known as feicui ( in Chinese) is a hard jade. See gemological properties of Jadeite below:

The term feicui came from An Analysis of the Structure of Chinese Characters, a book by Xu Shen of the Eastern Han dynasty, which states that fei is a red-feathered bird and cui, a green-feathered on. In ancient Chinese periods it was a common for the woman to adorn their jewellery with the pattern of birds. In the Song dynasty, fei and cui became one word to denote jade, but only the jade with a dark green color and not the Burma-produced intensely green jadeite.

Antique jade is actually ancient or very old jade stone normally made from nephrite.  Jadeite is believed to be in existence in China only after the Ming Dynasty.
