Classification of Jadeite

Jadeite can be classified into Type A, Type B, Type C and Type D jade. This classification system is used for judging whether the jadeite is Natural Fei Cui (Jadeite Jade) or artificially treated jadeite. Jadeite buyers may take into account the type of jadeite in evaluating its value.

Type A Jade
It is natural jadeite which has not been subject to any chemical treatment, impregnation or dyeing that artificially alters its crystalline structure or original color.

Type B Jade
Type B jade is chemically treated and resin impregnated jadeite. Lower quality natural jadeite with impurities, coarse texture or poor transparency can be bleached with strong acids, and then impregnated with epoxy resin. This treatment alters the crystalline structure of jadeite and enhances its transparency, but meanwhile may result in cracks on the surface, dull tone, and yellowish hue. Type B+C jade refers to the jadeite that has been dyed during the above treatment process.

Type C Jade
It refers to dyed jadeite. Jadeite of pale color is partially or wholly dyed green, red, purple, etc. However, such dyed color will fade and the luster may become dull over time.

Evaluation of Jadeite

Identification of jadeite authenticity and evaluation of jadeite quality require significant expertise and experience. In general, people may judge the quality of jadeite on the basis of these quality factors: color, clarity, transparency and cut

Color is an important value factor affecting the value of jadeite. The most desirable color will be the pure color, the purity of which may depend on the proportion of primary color and secondary color. For green jadeite, pure green is the most valuable, yellowish or bluish green are less valuable, and greyish green is the least valuable. Besides, intense and vivid colors with even coloration tend to be more desirable than lighter and weaker colors with uneven color distribution.

The less impurities and other inclusions there are in the jadeite, the more valuable the jadeite is. There are mainly two kinds of inclusions, white inclusions and black inclusions. Comparatively speaking, black inclusions are more obvious than white ones, thus resulting in lower value of the jadeite. *Please note all natural jadeite have inclusions.

When light penetrates the surface of jadeite, the transparent and fine-textured jadeite has alluring brilliance, thus giving it a higher value; while the opaque and coarse-textured jadeite reflects dull light, thus decreasing its value.

Polishing and craving are far more important to jadeite than to other gemstones. Jadeite can be classified into cabochons and carved pieces. The finest-quality jadeite is usually cut into cabochons, and jadeite with cracks will not to be fashioned into cabochons. The proportion, thickness and symmetry of the cabochon also have substantial impact on the finished products. When judging carved jadeite pieces, their overall aesthetics and carving craftsmanship shall be evaluated.
