Modernist Concentric Circle Kinetic Armillary Sculpture
Decorative Object / Kinetic Sculpture · Unattributed Modernist workshop; style consistent with 20th-century European or American industrial design.
Pattern: Geometric Abstract / Industrial Modernism

Type
Decorative Object / Kinetic Sculpture
Maker
Unattributed Modernist workshop; style consistent with 20th-century European or American industrial design.
Material
Likely Aluminum, Polished Steel, or Chrome-plated base metal (Nickel Silver/German Silver). Extremely unlikely to be solid Sterling Silver due to construction screws and industrial finish.
Dimensions
Estimated height 40-50 cm, base diameter 15 cm. Weight suggests industrial metal rather than precious silver (approx. 2-3 kg).
Description
A striking modernist kinetic sculpture featuring a series of concentric metal rings that graduate in size. The piece is mounted on a heavy, stepped circular base and terminates in a central polished sphere. Its design evokes an armillary sphere or a stylized planetary system, making it a quintessential office or gallery statement piece.
Key Features
Concentric ring assembly, kinetic movement, stepped trumpet base, polished industrial aesthetic.
Material & Composition
Likely Aluminum, Polished Steel, or Chrome-plated base metal (Nickel Silver/German Silver). Extremely unlikely to be solid Sterling Silver due to construction screws and industrial finish.
Finish & Decoration
Polished satin finish with visible industrial machining. Features concentric planetary rings and a central sphere (orb) representing an armillary or celestial model.
Hallmarks & Stamps
No visible hallmarks or silver fineness stamps; likely marked 'Chrome,' 'Made in...' or unmarked on the underside of the base.
Construction Details
Machine-lathed base, die-cut or extruded rings, assembled with visible slotted tension screws and pivot pins to allow kinetic rotation.
Functional Features
Kinetic rotation; each ring is mounted on an axis to allow independent movement around a central point.
Handle & Grip Details
Trumpet-style pedestal base designed for tabletop display; no functional handles.
Craftsmanship Details
High-quality industrial machining; uniform ring thickness and precise pivot alignment suggest machine-aided factory production.
Authentication Indicators
Lack of lion passant or .925 stamps; use of hardware screws instead of silver solder; metal luster consistent with aluminum or chrome.
Origin & Manufacturing
Likely USA, Germany, or Italy. Mass-produced or small-batch industrial manufacture rather than traditional silversmithing.
Era & Period
Mid-Century Modern to Contemporary Industrial (1960s–Present). Influenced by Atomic Age and Brutalist design movements.
Age Estimate
Late 20th Century, circa 1970-1990 based on screw types and metal finishing.
Cultural Significance
Represents the 'Space Age' design trend where celestial and scientific forms were adapted into high-end home decor.
Condition Notes
Good condition. Surface shows minor oxidation (pitting characteristic of chrome/nickel plate) and light surface scratches. Mechanical pivots appear functional.
Value Estimate
Range: $150–$450 depending on height and manufacturer. If identified as a specific designer (e.g., Curtis Jere), value could exceed $1,000.
Care & Maintenance
Clean with a dry microfiber cloth; use specialized chrome polish if plated; avoid silver dips which can damage non-silver alloy coatings.
Similar Pieces
Authentic silver armillary spheres by makers like Asprey (which would be hallmarked); decorative chrome pieces by Restoration Hardware or Global Views.
Interesting Facts
Armillary spheres were originally astronomical instruments used to model the heavens; this 20th-century interpretation strips the function for pure geometric form.
