Identification of typical jadeite varieties: reflective observation of glass species: strong light transmission observation of internal condensation: most light can pass through the sample, and internal characteristics can be seen. Typical sub-transparent species: ice species reflection observation: weak internal convergence light.
There are several explanations about the origin of jade's name. A name from a bird. The feathers of this bird are very bright. The male feathers are red and the female feathers are green.
