Hetian jade 4d pure gold refers to Hetian jade products with four-layer composite inlay technology. Usually, it includes: a jade with a bottom, on which a plastic mold is stuck, and a gold foil is stuck, and a small diamond or artificial gem is inlaid in a subtle place, with four layers in total.

Structure:

The main structures of Hetian jade are metamorphic structures, including felted aphanitic metamorphic structures, microfiber-aphanitic metamorphic structures, microfiber metamorphic structures, microplate-aphanitic metamorphic structures, microplate metamorphic structures and microscopic radial (broom-like) metamorphic structures. Secondly, it also includes uncommon residual structures and metasomatic crown structures.

Although Hetian jade mineral particles have certain orientation, they are not firm, and occasionally the particles have wave extinction and plastic deformation. All these indicate that the stress intensity of metamorphism is within the elastic limit of minerals.

The main structures of Hetian jade are blocky structure and flaky structure, and blocky structure is more common.
