How to Identify Jade Quality?
Experts believe that, although more expensive, diamonds and gold cannot be compared with jade - jade is animated with a soul.
To obtain a real and choice jade article, you should take pains to learn and appreciate it. The criteria lie in the brightness of color and luster, compactness of inner structure, and the delicacy of the craftwork.
For example, nephrite creates an oily luster and jadeite creates a vitreous luster. Tiny cracks can lower the value of jade; on real jade, air bubbles cannot be seen; the more lenitive the higher quality of jade, and so on.

Likings for particular colors vary very considerably from region to region and culture to culture. In green jade alone, the connoisseurs differentiate between seven main qualities, from the intense, even green of imperial jade, via apple green and spinach green, all the way to the lighter and to more heavily speckled shades of green.

Jade is usually worked into two categories: plain polished shapes such as cabochon and carved designs.
Plain polished shapes require higher grade material without flaws. Ratings are made on their proportion and symmetry. For example, a well-cut cabochon should be neither too thick nor too thin in relation to the area of its top surface. It's "bulge" should be centered, prominent but not exaggerated.
Carved designs are often used to eliminate or minimize the effect of flaws and cracks. They are assessed on their aesthetics and the workmanship of the details.
