Detailed knowledge of the difference between jadeite and nephrite

There are two types of jade, one is jadeite (also known as jade) and the other is nephrite. Nephrite is more common, but both are tough, fine-grained rocks suitable for carving. Jadeite is composed of pyroxene crystals with interlocking grain structure. It has a variety of appearances and colors, including green, lavender, and white. There are two types of jadeite, one is jadeite (also known as jade), and the other is nephrite. Nephrite is more common, but both are tough, fine-grained rocks suitable for carving. Jadeite is composed of pyroxene crystals with interlocking grain structure and has a variety of colors, including green, lavender, white, pink, brown, red, blue, black, orange and yellow. The most precious imperial jade is rich in dark green due to the presence of chromium. After polishing, jadeite usually has a dimpled appearance.　　 characteristics of jadeite: 　　 composition: sodium aluminum silicate 　　hardness: 7　　 specific gravity: 3.33　　refractive index: 1.66-1.68　　 birefringence: 0.012 Origin: Jadeite is produced in metamorphic rocks with alluvial pebbles and boulders. The brown surface is formed due to weathering, which is often incorporated into carvings and finished products. The most important source of jade is in Myanmar, which has been providing carving materials to China to Indians in Central America for more than 200 years. Jadeite is also found in Japan and California in the United States. Characteristics of nephrite: 　　 composition: calcium, magnesium, iron silicate Hardness: 6.5　　 specific gravity: 2.96　　 refractive index: 1.61-1.63　　 birefringence: 0.027　　 place of origin: Chinese carved nephrite with a history of more than 2,000 years, the material was imported from Central Asia Texistan , And then entered from Myanmar. Others include Siberia (dark green with black spots), Russia (Polish) and China. Nephrite is also distributed in various rocks in the North Island and South Island of New Zealand. There are also Australia (black nephrite), the United States, Canada, Mexico, Brazil, Taiwan, Zimbabwe (dark green), Italy, Poland, Germany and Switzerland.　　 Nephrite is confirmed to be another kind of jade, which is a fibrous amphibole crystal aggregate. The chain structure, which is tougher than steel, is regarded as a superior carving material, first used as a weapon, and later as an ornament. Its color varies from dark green nephrite rich in iron to a creamy variant rich in magnesium, which may be homogeneous, spotted or streaked.　　 The above is about the difference between jadeite and nephrite.
