Hallmarks & Stamps
Comprehensive British Hallmark: JH (Maker's mark for John Hart); Three-pointed shield with scales (Symbol for the Edinburgh Assay Office Convention mark); '9' and '.375' (9-carat gold fineness); 'D' (Date letter for 1978).
Construction Details

Craftsmanship Details
High-quality punchwork. The interior finishing is smooth, indicating professional workshop standards. The hallmarks are struck 'squarely,' which is a sign of careful quality control during the assay process.
Authentication Indicators

Origin & Manufacturing

Era & Period
Modernist Scottish Revival/Post-War era. Specifically 1978, reflecting the continued popularity of Celtic Heritage designs in the late 20th century.

Cultural Significance

Condition Notes
Excellent condition. The hallmarks are exceptionally crisp with no signs of thinness from over-polishing. Minor surface micro-scratches consistent with gentle wear; no evidence of resizing which often cuts through the marks.
Value Estimate
£250 - £450 (USD $320 - $575) depending on the design on the exterior and the ring's weight. Items by John Hart carry a collector's premium above the scrap gold value.
Care & Maintenance
Clean with warm soapy water and a soft brush. Gold is softer than silver and should be kept away from harsh chemicals or abrasive surfaces. Store in a soft pouch to prevent scratches.
