What do you mean by natural jadeite (A goods)?
Jade A refers to natural jade that has not been filled and colored, and has long been recognized as A jade in the industry. Natural A-grade jadeite, born by absorbing the essence of heaven, earth, sun and moon, is full of spirituality.

To the naked eye, the texture is delicate, the color is soft and the stone lines are obvious; Slight impact, crisp and pleasant voice; It feels very heavy and is obviously different from other stones. It is characterized by a density of 3.32-3.34g/cm3, a refractive index of 1.66, a glass luster, a fiber interwoven structure under enlarged observation, and no fluorescence under ultraviolet lamp.

Traditionally called Cui or Jade, it is jadeite jade produced in Myanmar. Emerald is produced in Japan, Russia, Mexico, California and other places, but its quality and output are far less than that of Myanmar. Gemstone jadeite has been mined in Myanmar for a long time. For a long time, people only knew that Myanmar produces jadeite, so Burmese jade is synonymous with jadeite.

Structure refers to the degree of crystallization, crystal morphology, particle size and the arrangement of minerals that make up jadeite. Jadeite was formed by hydrothermal process, contact metasomatism and regional metamorphism under the background of high pressure and high temperature, medium temperature and low temperature. The mineral composition, crystallinity, crystal morphology, particle size and the arrangement relationship between minerals are complex and diverse, and the structural types are also diverse.
