Pre1932 British Gold Ring Assayed in Birmingham by: Yvonne
Maharba,
Thanks for reaching out Denise, II am so glad you found us!
The marking 15.625 on your ring denotes the purity of the metal. which is 15K. In the UK, 15 karat gold is 62.5% pure gold, which is denoted as 625.
Before 1932, jewellers stamped 15ct or 15.625., so this tells you, your ring which is stamped 15.625 was assayed before 1932.
The Anchor:is the Assay Office Mark, this means this piece was tested and hallmarked in Birmingham, England.
The "funny looking" M is called the Date Letter. In British hallmarking, each year is assigned a specific letter in a specific font and a specific shield shape. An ornate, cursive, or unusual-looking "M" was used in several date cycles, for example, a cursive letter M was in circulation in 1911.
