Teach you how to distinguish eight characteristics of Burmese a cargo jade

Myanmar a cargo jade

Now the technical indicators of jade identification have been unified. As a jade collection enthusiast, if you can't identify yourself, you can go to the nationally recognized jewelry appraisal center and ask for professional identification. How to identify eight characteristics of Myanmar a jadeite allows you to practice the eye.

Impurities: Jade a cargo is magnified and observed, sometimes see yellow, brown, black impurities; jade b goods are relatively pure, can not find impurities.

Gloss: After the surface of the jade a cargo has been polished, it is flat as a mirror, with strong reflective properties, and is made of glass luster. After the acid and alkali soaking treatment of the jadeite b, the structure is loose, and the dissolution pit is not seen before filling. It produces diffuse reflection and is pockmarked; after the jade b cargo is filled with glue, the surface is made of resin luster and has no spirituality; if jade b cargo is filled with rubber and then polished, the resin gloss spot is still visible in the filled pit, and the overall resin gloss Mixed with glass luster.

Color: Emerald a goods color natural, layered; jade b goods color is formed after the color of the color, bright and yellow. Due to the destruction of the jade structure, the original optical properties have also changed, so the color distribution of the jadeite goods has no layering and chaos.

Structure: It can make jadeite materials of jadeite b. It is mostly jadeite with more impurities and loose structure. After being soaked and etched by strong acid and alkali, some substances are brought in and out, forming corrosion between mineral crystals on the surface and inside. , the internal connected cracks and the surface channel network are generated, and the internal cracks are jagged tensile cracks. Under the condition of transmitted light, the internal longitudinal and transverse interlacing cracks are visible, which seriously affects the permeability; under the reflective condition, the surface of the dissolution pit or the net is clearly visible, and the original glass luster of the jadeite is lost.

Bubbles: Refilled jade b goods in the surface layer or cracks in the colloid visible residual bubbles.

Impurities: Jade a cargo is magnified and observed, sometimes see yellow, brown, black impurities; jade b goods are relatively pure, can not find impurities.

Fluorescence: Emerald b has a medium-yellow yellow-green, blue-green fluorescence.

Thermal reaction: Emerald a cargo does not melt below 800 °C, and the carbonized carbonation occurs after heating the jade b cargo at 200~300 °C. Density: In theory, the density of jadeite b is slightly lighter than that of a, but this point lacks practicality because the density of jadeite varies within a range.
