Date Letter, 15ct. Birmingham (1854-1932) by: Yvonne
Maharba,
Thanks for reaching out. So glad you found us.
Your 15-carat gold ring was made in Birmingham, England, and dates to between 1854 and 1932. The '15.625' tells you the gold purity (15 carats, which is 62.5% pure gold or 625 parts per thousand).
The anchor is the mark for the Birmingham Assay Office, and the 'M' is the date letter. The 15ct gold standard was abolished in 1932, so we know your ring is a genuine antique or an estate ring.
To narrow down the exact year, examine the exact font style and shield shape surrounding the date letter 'M', as British assay offices rotate through different alphabets and backgrounds.
