As a kind of jade, jadeite is different from other diamonds, sapphires and other precious stones in structure. The structure of jadeite belongs to polycrystalline polymerization structure, which makes the appearance of jadeite and diamond sapphire completely different, which may be the reason why jadeite is so aura and connotation compared with them. This result of jadeite also caused many colors to appear on a piece of jadeite. Such jadeite is very rare, such as three-color jadeite, or four-color and five-color jadeite. The more colors appear on a piece of jade, the rarer it is and the higher its value. It is quite rare to have red and green on a piece of jade, and the price will be higher if there is one more color. In ancient times, people implied the five colors of jade, namely red, green, purple, yellow and white, as a blessing for longevity and wealth. People often say that Fu Lushou tricolor jade refers to a piece of jade with red, green and purple colors on it. If any three colors appear on a piece of jade, this piece of jade can become a tricolor jade. Even in the Qing dynasty, there were very few jadeites with three colors on a piece of jadeite, which shows that there are few jadeites with three colors. For the appreciation of yellow plus green jadeite, we must first emphasize two elements: one is color; The second is design and sculpture. Yellow plus green jadeite is a kind of jadeite variety that wins by color. Yellow and green are required to be bright and bright, with strong contrast. The higher the color saturation, the more concentrated and valuable the color block area is. Of course, if the germplasm is more delicate and the water head is better on this basis, it will be icing on the cake. Yellow-green jade, with bright color, can reach the level of ice seeds, and is an extremely rare treasure. In addition to being processed into precious ornaments such as bracelets, yellow plus green jadeite is also a very good carving material, so its design level and the fineness of processing technology directly affect its artistry and price. We should pay attention to the use of colors, with distinct levels, reasonable and natural layout, so as to make the colors more vivid and rich, the texture more moist and transparent, and the closer it is to the real things in nature or people's imagination, the more delicious it will be.
