Hetian Yu is called China's national jade and continues to be used for 5,000 years. Hetian jade is not only beautiful, but also rare, so high-quality Hetian jade in the market is often expensive. However, is it worth every piece of Hetian jade? This is not the case. Today’s Hetian jade is not the same as Hetian jade. The quality and price gap are very large. We must open our eyes when buying, and don’t buy anything worthless.
In ancient times, Hetian jade mostly refers to the Wenrunmei stone from the Hetian region of Xinjiang. Hetian jade in the modern market refers to the hardness of 6-6.5; the refractive index is 1.606-1.632; the density is 2.90-3.10; the fiber with interwoven fiber structure As long as these physical indicators are met, Hetian jade is reflected in the certificate.
There are several jade stones in the Kunlun Mountains, such as Qinghai jade and Russian jade. Their hardness, density and refractive index are in this index range, and the color and texture are very close to that of Xinjiang Hetian jade. It is cheap and has become the main role of Xinjiang Hetian jade.
Qinghai jade
The overall texture of Qinghai Jade is very close to Hetian jade. The hardness, density and refractive index are basically in the same index.
However, when carefully observing Qinghai jade, its color is slightly changed. It is white in the blue, the internal particles are slightly thick, and it is dry and dry. It is generally watery, and the cleanliness is relatively low. The porridge inside the jade is not uniform enough. At around 1.60, the permeability is slightly stronger under the action of light, and there is a lack of warm feeling.
Russian jade
The Russian jade texture is also very close to Hetian jade. The interior of the jade body is often more delicate than Hetian jade. The grain structure is smaller, the oily feel is floating on the surface, the surface is oily and the stone grain is more, the impurities are more, and the common part of the same jade material is clean. Some areas are not clean and uneven, and the refractive index is about 1.58. The color of jade is more white and yellow, more attractive, and the surface is bright, but lacks depth and heavy feeling.
Korean jade
Korea's Hetian jade has high purity, uniform texture and hardness, uniform color, and its refractive index is about 1.62. The upper and lower deviations are small, the permeability is just right, the light is not transparent, and the reflected light is even and delicate. soft. The jade has the same color, the color difference is very small, and it is generally covered with gray, less water, stone, cloud, and motley.
