This vintage British ring features several stamps on the inside of its yellow gold band.
Gold purity mark – 375: Indicates 9 carat gold, containing 37.5% pure gold.
Additional hallmark symbols: Further marks are visible alongside the 375 stamp, although some are worn and difficult to distinguish.
Maker's or sponsor's mark: A separate stamped mark is visible inside the band. Its exact lettering and maker have not yet been conclusively identified.
Assay office: The ring has previously been described as bearing London assay marks. However, the assay office symbol requires further verification before it can be confidently attributed to London.
Date of manufacture: Not yet established from the available hallmark photographs.
These markings offer a fascinating glimpse into the ring's history and are shown in the accompanying close-up photographs.
Metal: Solid 9ct yellow gold, marked 375.
As with many vintage pieces, some hallmark impressions have softened with age and wear.
