Medium & Technique
Yellow gold (likely 14k or 18k) and round brilliant-cut diamonds. The technique involves lost-wax casting for the organic 'nugget' texture and prong-setting for the gemstones.
Creation Period
circa 1965-1975
Dimensions & Format
Approximately 20mm width at the face (estimated); standard finger size; three-dimensional sculptural format.
Subject Description
An asymmetrical cluster arrangement featuring multiple round brilliant diamonds of varying sizes. The gold mounting features a heavy, molten-like texture characteristic of the Brutalist aesthetic, evoking organic or tectonic formations.
Condition & Value Assessment
Condition Assessment
Good to Very Good. The diamonds appear secure, and the gold shows standard surface wear consistent with age (micro-scratches and slight patina).
Estimated Market Value
$2,500 - $4,500
Auction Estimate
$1,800 - $3,500
Provenance History
Likely acquired via private purchase or estate inheritance; no visible hallmarks or maker's marks are discernible in the photograph to provide a specific chain of ownership.
Art Historical Significance
This piece represents the mid-20th-century transition in jewelry design where the 'finished' look of traditional settings was replaced by raw, abstract, and sculptural 'wearable art' forms, influenced by artists like Barker and Grima.
Notable Features
The distinctive 'nugget' or molten texture of the gold and the random, asymmetrical placement of the diamonds which create a sense of natural movement rather than geometric rigidity.
Condition Issues
Visible surface abrasions on the gold shank; potential dirt accumulation beneath diamond pavilions requiring cleaning; minor thinning of the lower shank.
Conservation Recommendations
Professional ultrasonic cleaning; inspection of prongs by a master jeweler to ensure gemstone security; storage in a soft-lined jewelry box to prevent scratching.
