About the identification of jade

Having said so much basic knowledge, the following is the identification of actual combat:

Cui nature: Regardless of jade raw materials or finished products, as long as you carefully observe on the polished surface, you can usually see the variegated interweaving structure of the piebald. Two forms of jadeite crystals can be seen on a piece of jade, one is a slightly larger granular phenocryst, and the other is a small fibrous small crystal surrounded by plaques. Under normal circumstances, the same jadeite porphyry particles are uniform in size. A few days ago, some netizens also said that the jadeite microwave phenomenon, I have benefited a lot, I suggest you look at the forum.

Stone flower: There are small clumps in the jade, and the white fiber-like crystals with poor transparency are intertwined with stone flowers. The difference between this stone flower and phenocryst is that the plaque is transparent, and the stone flower is slightly transparent to opaque.

Color: The color of the jade is uneven. It is accompanied by a different shade of green or black on the base of white, enamel pink, oil cyan, and bean green. There is also a shame on the green background.

Gloss: The emerald has a bright luster and a good polish. It is bright and soft with a strong glass luster.

Density and Refractive Index: Jadeite has a high density and sinks rapidly in tribromomethane, while similar nephrite, serpentine jade, grape stone, quartzite jade, etc., are suspended or floated in tribromomethane. The emerald has a refractive index of about 1.66 (point test), while other similar jade are lower than 1.63.

Inclusions: The black mineral inclusions in the jade are mostly melted, the edges of the particles are loosely cloud-like, and the green is deeper around the black inclusions, with the saying “green with black”.

The water-holding is strong: that is, a drop of water is dripped on the finished jadeite, and the water droplets are raised higher.

In short, the main identification characteristics of jadeite are: uneven color, prolonged green trend; strong glass luster with oil; plaque interweaving structure; cool feeling, the color does not change under the Charles mirror.
