The main variety of Kunlun nephrite is also the one with the largest output, which is sometimes called "Qinghai White" in the industry. It is grayish white-waxy white, translucent, and its transparency is obviously better than that of Hetian jade. The texture is fine and moist, and the yield is large, and a small amount reaches the quality of "sheep fat white jade".
According to their different appearance characteristics, people in the industry vividly describe them as: milky white jade, transparent white jade, pear white, rice soup white and other varieties. Kunlun white jade is fine, smooth and uniform in texture, with large block size, which belongs to the first-class good material, but it has high transparency and insufficient dignified texture, especially after thinning.
There are also varieties of sugar-colored jade in Kunlun nephrite, mainly light yellow-brown uniform sugar-colored disseminated and spotted dark brown-yellow-brown sugar-colored. Its sugar color is either concentrated to form dark brown spots, or its color is too light, which makes little contribution to pretty color, destroys a lot of jade and has low utilization value.
It is light grayish green-cyan gray, light yellow gray, etc. , elegant and refreshing color, translucent, delicate and even texture. The transparency is obviously greater than that of Hetian jade, with sufficient water head and good uniformity, which is very popular among people in the industry. It is often vividly called: transparent white green, light blue white, duck egg green and so on.
Blue-gray-dark gray-green, dull tone, semi-transparency and texture are often better than Hetian jade, suitable for making large and medium-sized ornaments and utensils. After thinning, the color tone turns sunny, solemn and elegant, and the voice is sonorous and full of charm. It is a high-quality sapphire.
Light grayish purple to smoky gray, with a slight gray tone. Translucent, delicate and moist, some people call it violet, lotus root jade, sapphire and so on. It is rare in traditional hetian jade varieties. Because of its remarkable color characteristics, it can be said that it is a symbolic variety of nephrite in Qinghai. This variety is produced by independent thin layer, and there are also white jade materials with black edges and black leather materials with local characteristics.
It is more appropriate to classify it as sapphire, which can be called smoky sapphire and purple jade can be called purple sapphire. Smoke sapphire enriches the pretty varieties of nephrite, such as "green shrimp", pigeon (gray raindrop), black and white double happiness (badger) and so on.
Kunlun topaz and yellow mouth material are produced in Xigou, Xiaozaohuo area, Golmud City, and the cross section is yellow and blue, so it is called "yellow mouth material". These materials are delicate and clean, and the most commendable thing is that the foot oil and water head are good, which is deeply loved by people. People have compared topaz in different areas of China in the market, which is brighter than that of Liaoning River and more delicate than that of Xinjiang. The main disadvantages are: small block, many cracks and less success, but it is difficult to produce in recent years. The excavated jade will even grow into a rough milky white and basically lose its yellow color. I really don't know how long the yellow mouth material can be mined.
Light emerald green, its green characteristics are like tender green jade, which is obviously different from the green of sapphire and jasper. This kind of green nephrite is rarely produced alone, but adheres to one side of white jade and sapphire raw materials or forms a sandwich, and the distribution of lumps is often related to sandy and mottled stones.
Some of its finished products are all green, and some form beautiful colors on white jade and blue-and-white jade carvings, which is rare in Hetian jade products in the past. All green and beautiful products have become hot spots in jade collection for a period of time. According to its color characteristics, the name emerald is more in line with the naming standard.
