Identification of Hetian jade and similar jade
At present, the similar jade in Hetian jade in China is serpentine jade, quartzite, albite jade and glass, etc. Below we introduce the identification methods one by one: 1. Hetian jade The actinolite and tremolite are the main constituent minerals of nephrite and are fibrous aggregates of minerals. The main differences are as follows: first, gloss. Hetian jade is grease luster, glass luster or waxy luster; second, structure. The nephrite is a felt-like structure, and its structural particles are finer. At the same time, the appearance of nephrite is more uniform and fine in color; third, density. Nephrite is 2.95g/cm3; fourth, Hetian jade has a refractive index of 1.61. 2, serpentine jade Serpentine is the main constituent mineral of serpentine jade. It has the following differences with Hetian jade. The first, color, serpentine jade is generally yellow-green in color, relatively light in color, and evenly distributed. luster. Serpentine jade gloss is glass to waxy luster, and there is no green; third, hardness. Compared with Hetian jade, the density of serpentine jade is relatively high, between 2.5 and 6. The density of serpentine jade is 2.57g/cm3, which is lower than that of Hetian jade. ﹑Exterior. Serpentine jade often has white or black clumps and spots. 3. Quartzite The crystallization and cryptocrystalline are the main constituent minerals of quartzite, which have the following differences compared with Hetian jade: first, structure. Nephrite is a blanket-like structure, and quartzite is a granular structure. Compared with Hetian jade, the particles are larger. The second, density, quartzite density is 2.65g/cm3, which is lower than that of Hetian jade. Third, refraction The rate, quartzite is 1.54; fourth, the absorption spectrum, quartzite generally does not have a characteristic absorption line. 4, glass The glass is amorphous, and various colors often appear on the market. Compared with jasper, the appearance is more similar. Compared with Hetian jade, it has the following differences: first, structure, amorphous structure, color in appearance The distribution is more uniform; secondly, the density of the glass is 2.30-4.50g/cm3 compared with Hetian jade; the third, the refractive index, the refractive index of Hetian jade is 1.61, and the glass is 1.47-1.700.
