1. Qingshui is not a technical term for jadeite. It's just that jadeite with this characteristic is called clear water material or clear water bottom. Sunny land can be glass, ice or wax. Common clear water also has light blue or green, so its color can basically be divided into light blue, light green and light blue green. Clear water and jade are compatible in color, and the color is even and soft, which looks like a clear sky, giving people a fresh and comfortable feeling.
2. The varieties of blue water jadeite are older, the texture is delicate, and the water quality is better, and some of them are even above the ice jadeite. The color of blue water jadeite belongs to the root background color, and the background color is still in the blue range, with few floating flowers. Blue water is relatively uniform and delicate, unlike other jadeites, which are strip or block emeralds. However, the color of blue water jade is good or bad, and the best is pure blue. Green or gray will make jadeite look dull and not cool enough.
3. Oil green species is a kind of jade with fine texture, transparency and deep oil-like color. Its green color is obviously impure and contains gray-blue components, so it is dull, dark and not bright enough. The color of oil-washed jadeite can be changed from shallow to deep, and the transparency is generally good. The crystal structure is usually fibrous and can be very fine. Because of its oily luster, it is called oil green, and the dark oil green jade is also called melon skin oil green by experts. All germplasm with enough oil and delicate color are basically classified as oil green. (Information comes from a piece of jewelry)
