What is jade a cargo? Emerald a goods refers to natural jade that has not been chemically treated by filling and coloring. It has long been recognized in the industry and is customary as a jadeite. The natural a-car jade absorbs the essence of the sun and the moon, and is full of spirituality. It is also called “living jade†in the folk. After a long period of wearing, the jade will be more moisturized with the human skin. The human body will also receive health care, and the wearer's mood is also very pleasant. This is what people often say, "people raise jade, jade raise people", and people can be mutually cultivated and human jade can communicate.
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.
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.
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.
Impurities: Jade a cargo is magnified and observed, sometimes see yellow, brown, black impurities; jade b goods are relatively pure, can not find impurities.
Bubbles: Refilled jade b goods in the surface layer or cracks in the colloid visible residual bubbles.
Thermal reaction: jade a cargo does not melt below 800 ° C, filled with jade b goods heated 200 ~ 300 ° C after carbonization.
Fluorescence: Emerald b has a medium-to-medium yellow-green, blue-green fluorescence.
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.
