Lapis lazuli-style circular stone sculpture on marble base

This decorative object consists of a large, torus-shaped ring mounted on a rectangular white stone base. The ring features a tiled surface of modular stone sections displaying a deep, mottled blue color with white and gold-toned inclusions, which is stylistically consistent with lapis lazuli or a high-quality dyed stone simulant. The ring is punctuated by four evenly spaced metallic bands, possibly brass or gold-toned metal, providing structural contrast. The base appears to be a solid block of white honed marble or a similar light-colored stone. The craftsmanship suggests a contemporary aesthetic, possibly mid-to-late 20th century or modern, and is stylistically consistent with luxury home accessories often found in high-end decor boutiques. The surface shows a high-gloss polished finish, indicating quality lapidary work. There are no maker's marks, signatures, or branding visible in the image to provide a firm attribution to a specific designer or manufacturer. Consequently, this identification is based solely on the object's visual characteristics and material cues from the photograph. The condition appears sound with no immediately visible chips or fractures, though light surface scuffing may be present upon physical inspection.

I have examined the digital image of this decorative torus-shaped sculpture. Based on what I can see, the piece features a tiled application of blue stone, possibly lapis lazuli or a high-quality mineral simulant, mounted to a stone base. While the visual indicators suggest luxury lapidary work consistent with mid-to-late 20th-century high-end home accessories, I cannot verify the specific materials or the internal construction from a photo alone. The absence of visible maker's marks means any attribution to a specific designer or luxury brand must remain a hypothesis at this stage. The estimated value reflects market demand for high-end decorative objects in this style. This valuation assumes the materials are natural stone rather than resin composites. A physical inspection would be required to confirm the density of the mineral sections and to inspect for any hidden hallmarks or signatures on the underside of the base. If this item were verified as the work of a notable 20th-century designer or a renowned luxury maison, the value could exceed the current estimate significantly. Conversely, if physical testing identifies the materials as synthetic or modern dyed aggregates, the value would likely decrease to a range of $150 - $250. General market interest in semi-precious stone decor remains stable among collectors of modern design, but final value is heavily contingent on material purity and documented provenance, neither of which can be established without in-person scientific testing or further documentation.
