The history and culture of jadeite goes hand in hand with the history of jadeite. Looking at the development history of jadeite, It can be found that China is an ancient civilization with a long history and culture of jade. Jadeite has become one of the inheritors of jade culture. Influencing the thoughts and ideas of generations of Chinese people, The rich and colorful colors of jade are also deeply loved by the Chinese people. Jade has a variety of colors, and the basic tones are green, red, purple, white, black, and yellow. Among them, green is the most varied, with a wide variety of colors and the highest value. Several color combinations are also often pursued by some enthusiasts. So how is the color of jade formed? The color of jade is related to its absorption of light. Light absorption is related to the specific chemical composition and crystal structure of jadeite. Jade comes in a variety of colors. According to the geological causes of jadeite's color, Can be divided into primary colors and secondary colors. The original color refers to the color of jadeite below the surface. Colors formed under various geological conditions. This color is closely related to the chemical elements and mineral composition of jadeite minerals. That is the color formed during the crystallization process of jade crystals. It is a relatively fixed color and cannot be dissolved by acid. Secondary colors refer to colors formed under geological conditions. After emerging from the surface, jade is under the conditions of normal temperature, pressure, oxidation and high water content. Many minerals are chemically unstable, and coupled with the temperature difference between day and night, Physical weathering and chemical weathering will occur. As a result of oxidation and hydrolysis, a weathering crust will form on the surface of jade. Weathering crusts often appear yellow, brown, brownish red, and maroon. These colors are not the inherent colors of jade crystals. The color is unstable and may be completely dissolved by soaking in strong acid, causing the jade to fade. The green color is common in jade. The green coloring element in jade is chromium ion, which is the primary color. Jadeite can produce color as long as it contains a few parts per million of chromium ions. If iron ions are involved in the coloring, it will turn into dark green, or black green, yellow green, bean green, etc. The red color in jade is a secondary color, called jadeite. It is formed by iron, manganese and other substances filling the spaces between grains or in cracks. If it contains high-valent iron and manganese, the color is mostly red. If it contains more low-valence colors, it is yellow. The purple color in jade is a native color, also known as spring color in the industry. The main colorant is manganese ions. The black color in jade looks very black on the surface, but appears as a dark green color under the light. The white color in jade is the original color, and the chemical composition of jade is very pure. It does not contain pigment ions and appears white or colorless. White jade includes transparent glass jade and ice jade. This kind of jade has a delicate texture and is as transparent as water. The creation of colorful jade is very strict in terms of subject selection, conception, theme, composition, carving, polishing, etc. One must have a profound cultural and artistic foundation to create works with unique artistic beauty. A colorful jade artwork that achieves a perfect combination of color, material and meaning. What is the value of that colorful jade? Colorful jade has rich and bright colors and is more difficult to create, so it is more valuable. In the current jade market, colored jade is more acceptable. Two-color jade is hard to come by. The three-color ones are very valuable, and the colorful ones are rare. The more colors, the higher the value, and the higher the collection value. In general, colorful jade has beautiful colors, is difficult to create, and has great craftsmanship and aesthetic value.
