Let's talk about the difference between jadeite and jadeite.

Compared with emeralds, jadeite has a lower hardness of 7 Mohs. The specific gravity is 33 ~ 34 g/cm3. The crystal structure is more refined.

The difference between them lies in different hardness, different luster and different categories.

Emerald belongs to beryl family and belongs to hexagonal system. Emerald crystals are usually hexagonal columns with few vertebral surfaces. There are pits on the cylindrical surface and the bottom axial surface. Almost all emeralds are broken in appearance, with many inclusions and extremely rare crystals, because they are generated in rock strata that are often squeezed by stress.

1. Emerald is a single crystal gem mainly made of beryllium-aluminum silicate (Be3Al2[Si6O 18]), belonging to beryl family. Jadeite is a kind of jadeite composed of polycrystals mainly containing sodium aluminosilicate (NaAl9(Si2O6)).

Because gems are mostly single crystal, the chemical composition is relatively uniform and pure, so the color is single; Emerald is rich and colorful because the content of various mineral raw materials is different, and green is the top grade.

The correct definition of jadeite with different properties is fibrous aggregate composed of pyroxene minerals mainly composed of jadeite minerals. Emerald is known as the king of emeralds, as rare as the bright red Ulan Nu, and it is one of the four precious gems (red, blue, emerald and diamond) recognized by the international jewelry industry.
