Jade
by S. Thai Vo

The term jade encompasses two tough, compact, fine-grained materials: jadeite and nephrite. Although this article deals mainly with the jadeite jade used in fine jewelry, we must briefly discuss the differences from nephrite, which is the much more abundant jade.

In the popular mind,jade is almost exclusively identified with Chinese art. However, jadeite, known generally as Chinese jade, did not enter China until the eighteenth century A.D. Jadeite is found in Burma, not in China. The Chen Yu, the tough green jade material that ancient Chinese prized above all else, was probably nephrite. Together, jadeite and nephrite have more simulants than most other gems. With so many materials touted as jade, the buyer must be aware of the names of these simulants as well as their key identifying characteristics.

Jadeite

Nephrite

While visual examination is not enough to identify the material conclusively, it renders clues that are certainly invaluable in the identification process. Some visual methods of examination include checking the texture, surface luster, fracture surface, and inclusions/dyes.

Texture
Jade is not an extremely hard material. Jadeite is listed as 6.5 to 7 on the Mohs Scale of Hardness, and nephrite is listed as 6 to 6.5. Diamonds are listed as 10. The toughness of jade, however, is unsurpassed. The toughness of a material is related to its internal structure, which is different for nephrite and jadeite. The internal structure, in turn, is often reflected in the texture of the stone. Jadeite normally looks granular while nephrite looks fibrous. None of the jade simulants have the tightly aggregated structures of either jadeite or nephrite.

Surface Luster
Texture may affect luster in the case of jade; the luster of most jade is "vitreous" or greasy.

Fracture Surface
A granular fracture like that of a lump of sugar is characteristic of jadeite. The splintery fracture, like the surface of a broken piece of wood is most often seen on nephrite.

Inclusions/Dyes
Inclusions can help in identifying the gem material. Think of inclusions as fingerprints and not as flaws. The dyes can be detected under magnification.


Natural, untreated jadeite jade. The only acceptable process after polishing is surface waxing with ordinary beeswax, to fill the stone's natural and microscopic surface pores, as has been done for centuries. A-type jade is the good stuff.

"B-type" Jade
Bleached, polymer-impregnated jadeite jade. The chemical process to create B-type jade results in the stone being entirely covered with a hard, clear plastic-like coating. B-type jade is the bad stuff.

"C-type" Jade
Coated and dyed jade. This kind of jade is usually dyed green or lavender, but sometimes red or yellow as well. C-type jade is also the bad stuff.

"D-type" Jade
Bleached, dyed, coated, polymer-impregnated jadeite jade. D-type jade is the worst of all jade types.
