Mid-Century Brutalist Gold-Plated Costume Statement Piece

Type

Jewelry (Likely Ring or Brooch)

Purity

Non-solid; base metal with gold plating or wash. The high degree of surface pitting and dark oxidation suggests a low-karat wash or costume plating rather than solid gold.

Gold Type

Yellow gold finish (simulated). The tone is a brassy, deep yellow indicative of fashion jewelry alloys.

Weight

15 to 25 grams, depending on whether it is a ring or a brooch. The irregular, chunky form suggests substantial heft for its size.

Description

This striking Brutalist-style piece captures the raw, organic energy of the mid-20th-century avant-garde movement. Featuring a deeply textured gold-tone frame that mimics molten metal or volcanic rock, the piece centers on a sharp, geometric dark stone that provides a stark contrast to the chaotic metalwork. It is a bold statement of mid-century fashion, designed to be worn as a conversation piece.

Key Features

Deeply recessed textures, jagged 'shag' edge, and a central table-cut slab stone characteristic of the 'ugly-cool' aesthetic of the 1970s.

Color & Finish

The finish is an antiqued yellow gold with a high-relief, irregular texture. There is significant patina and darkening in the recessed areas, likely caused by oxidation of the base metal underneath the plating.

Hallmarks & Stamps

No hallmarks are visible in this macro profile shot. Costume pieces of this era often featured a maker's cartouche on the reverse side or inner band.

Dimensions Estimate

Approximately 30mm x 25mm for the face; if a ring, likely size 6-8; if a brooch, standard lapel size.

Gemstones & Inlays

Centrally featured is a large, dark grey/black hematite or glass cabochon/table-cut stone. It appears to be an opaque 'hematone' glass or a synthetic mineral typical of mid-20th-century costume jewelry.

Clasp & Closure

Not visible; likely a standard pin-back for a brooch or a simple thick band for a ring.

Chain & Links

Not applicable. The item features a cast, textured 'lava' or 'bark' frame around the central stone.

Craftsmanship Details

Cast metal construction with a cold-set stone. The metalwork is designed to look hand-forged or 'random,' though it is likely a mass-produced cast from a carved wax original.

Authentication Indicators

Red flags for solid gold include the uneven wear (plating loss), the grainy texture of the casting which suggests a centrifugal cast base metal, and the lack of high-purity brilliance.

Origin & Maker

Unidentified; style is reminiscent of makers like Sarah Coventry, Monet, or independent artisans of the late 1960s who favored organic, cast-gold-tone textures.

Era & Period

Brutalist era (circa 1960s-1970s). This is evidenced by the jagged, organic, and architectural metalwork that defines the 'Brutalist' aesthetic in jewelry.

Age Estimate

Likely manufactured between 1965 and 1975 based on the casting style and stone choice.

Cultural Significance

Reflects the 1970s shift toward 'Earth' tones and organic forms in fashion, moving away from the refined elegance of the 1950s toward more expressive, sculptural wearable art.

Condition Notes

Condition is Fair to Good. Assessment shows significant 'brassing' where the gold plating is thinning, exposing a darker base metal. The stone shows surface abrasions and some chipped edges on the facets.

Value Estimate

Subjective/Collector Value: $25 - $65. The value resides in the design aesthetic and vintage appeal rather than precious metal content.

Care & Maintenance

Do not use jewelry cleaner or ultrasonic cleaners, as they will strip the remaining plating. Wipe with a dry microfiber cloth only. Store in a dry environment to prevent further oxidation.

Similar Items

Modernist gold-plated jewelry from Kramer of New York or high-end vintage costume pieces by Christian Dior (which often used similar heavy textures but with higher quality plating).

Interesting Facts

Brutalist jewelry was a reaction against the sleek, polished lines of traditional jewelry, drawing inspiration from chunky architectural concrete structures of the post-war era.
