Beveled Rectangular Green Aventurine or Jadeite Decorative Fragment

This item is a rectangular block of dense, mottled green stone, likely green aventurine or jadeite, featuring decorative beveled edges on three visible sides. The stone displays a rich, forest-green hue with significant internal variation including lighter green flecks and darker inclusions characteristic of natural mineral formations. The top surface and side bevels are polished to a satin finish, while one large vertical face appears roughly cut or sheared, exhibiting a granular, crystalline texture that contrasts with the smooth exterior. This unfinished edge suggests the piece may be a component of a larger architectural or decorative assembly, such as a clock base, desk set, or specialized paperweight. Physically, the piece appears to be approximately 3 to 4 inches in width. Condition-wise, it shows minor edge wear and tiny surface flecks which are typical for semi-precious stone materials. The craftsmanship is evident in the precise angles of the beveling, although no maker's marks or signatures are visible. Its style is consistent with mid-20th-century lapidary work or Art Deco influence if part of a larger object.
