What are weathered, thin-skinned jadeite boulders referred to as?

The term "rice jade" specifically refers to weathered, thin-skinned jadeite boulders that exhibit a unique appearance resembling grains of rice. This type of jadeite forms under certain geological conditions that contribute to its distinct textures and surfaces. The weathering process can enhance the visual characteristics of the jadeite, leading to the formation of the thin, skin-like exterior that defines rice jade.

This contrasts with other types of jade, which may not exhibit these specific surface qualities. In the context of jadeite boulders, differentiating between "rice jade" and other terms such as "old jade" or "raw jade" is important for understanding their value and applications in jewelry and art. "Textured jade," while it may describe certain surface features, does not specifically denote the weathered thin-skinned characteristics of these boulders. Thus, the correct identification of "rice jade" highlights a specific condition and aesthetic of jadeite boulders that is recognized in the field.
