The identification of jadeite mainly includes the following aspects:
Color: the color is floating and fuzzy, distributed along the crack, and it is artificial dyeing. Natural jadeite is mostly bright and colorful, penetrating into the bone marrow and wood.
Texture: Artificial jadeite is dull in texture, and jadeite of the same size is lighter in weight. The natural jadeite is glassy, brighter and heavier.
Water head: Due to chemical treatment, the water head or transparency of artificially treated jadeite will be affected. Even with glue treatment, most of the water heads are very low or even dry.
