2. Guizhou jadeite, a precious jade, was discovered in Qinglong Dachang, Guizhou Province in 1950s and belongs to a new jade species in China. Known as "Guizhou jade" and "colored jade" because of its gorgeous color, moist jade and hardness close to jade, it is a high-grade raw material for making jewelry and jade.
3. Guicui, also known as Guizhou Jade, is produced in Dachang Town, Qinglong County, Buyi and Miao Autonomous Prefecture, southwest Guizhou Province. This stone is a fine-grained quartzite containing green kaolinite. Most of them are light green, with uneven color and glass luster. The appearance is similar to that of jadeite, but it is not pure and contains many impurities. It is a low-grade jade material.
4. Silicotite is mainly composed of quartz, followed by kaolinite and antimony ore. Guicui has sky blue, emerald green, light green, grayish yellow, red and other colors, with sky blue and emerald green being the best. Most silicon jadeite has glass luster, slightly transparent, granular structure, inclusion structure and block structure.
5. Guizhou jade is jadeite, which is a fibrous aggregate composed of pyroxene minerals. It has great economic value and ornamental value. Formation reason: Jade is a dense and massive aggregate formed by countless fine fibrous mineral crystallites, mainly jadeite.
6. In terms of formation, silicon emerald evolved from dickite. Because of the fine texture of dickite, its composition is still fine and moist after silica silicification, which is incomparable to other minerals after silicification.
