Vintage Brutalist Rose Gold Rectangular Relief Plaque
Plaque / Decorative Relief Art · Rose Gold / Pink Gold. The deep reddish-brown hue indicates a heavy copper alloy often used in Mid-Century jewelry and art pieces to achieve a warm, earthy tone.
Purity: Lower Karat (estimated 10K-14K) or Gold-Plated Bronze/Copper. Significant oxidation suggests an alloy with high copper content (41.7% to 58.5% gold or a base metal alloy).

Description
A striking example of Brutalist metalwork, this rectangular plaque features a high-relief abstract landscape or figurative scene. The metal flows across the surface in a molten fashion, creating a sense of raw energy and geological formation. Its deep rose-gold hue provides a sophisticated yet industrial aesthetic, typical of the artist-led jewelry movement of the late mid-century.
Key Features
Abstract tectonic relief, signature hand-etched initials, deep rose-gold patina, and intentional 'crude' casting textures that celebrate the nature of the metal.
Color & Finish
Deep Coppery-Rose with a heavy aged patina. Finish is textured, cast, and organic, consistent with the Brutalist art movement, showing significant surface oxidation.
Hallmarks & Stamps
Hand-etched initials or maker mark visible on the bottom right corner (possibly 'HR' or 'HB'). No standard purity stamps are visible on the face; they may be on the reverse side.
Dimensions Estimate
Length: 5.5 - 6.0 inches; Width: 1.25 - 1.5 inches; Thickness: 3-5mm at the highest relief points.
Gemstones & Inlays
None. The piece relies entirely on tectonic metalwork and high-relief sculptural elements for visual interest.
Clasp & Closure
N/A. Likely a flat back; may have had a pin-back attachment removed or was intended as an inset for a box or desk accessory.
Chain & Links
N/A. The structure is a single solid cast rectangular form with integrated sculptural details.
Craftsmanship Details
Hand-carved wax model followed by casting. The soldering is invisible as the relief is integrated. The surface is left 'as-cast' with manual chasing on the signature.
Authentication Indicators
The casting method (lost wax or sand cast) is authentic to the period. The wear patterns and unique artisan mark distinguish it from mass-produced modern reproductions.
Origin & Maker
Likely American or Scandinavian studio artist. The 'HR' mark suggests an independent artisan or a boutique foundry specializing in wearable art or decorative objects.
Era & Period
Mid-Century Modern / Brutalist (circa 1960s-1970s). The jagged, abstract, and unfinished 'raw metal' aesthetic is a hallmark of this period.
Age Estimate
Circa 1965-1975. The specific style of casting and the degree of oxidation on the gold-copper alloy are consistent with this 50-year age range.
Cultural Significance
Represents the shift in the late 20th century where gold was viewed not just as bullion or wealth, but as a medium for avant-garde sculptural expression.
Condition Notes
Good / Fair. Significant surface oxidation and darkening (toning). No structural cracks, but the edges show some minor casting pits and wear consistent with age.
Value Estimate
Primarily valued as a collectible art object. Melt value depends on XRF testing for purity; collectible value estimated at $400-$800 to a mid-century art enthusiast.
Care & Maintenance
Do not use harsh chemical cleaners which would strip the historical patina. Clean with a soft, dry cloth. Avoid moisture to prevent further copper-oxidation (greening).

Interesting Facts
The Brutalist movement in gold and jewelry was a reaction against the polished, refined styles of the 1950s, emphasizing 'truth' in materials and the beauty of the casting process.
