Art Nouveau 1.17 Carat Old European Cut Diamond Yellow Gold and Black Enamel Engagement Ring
Circa 1911

Antique British Art Nouveau engagement ring centered with a GIA certified 1.17 carat old European cut diamond and black enamel within a intricately carved 18k yellow gold setting. This ring carries several hallmarks, the crown for gold, “18” indicating 18 carat purity, and the anchor for the Birmingham Assay Office, along with the 1911 date letter “m” and the maker’s mark “H.W.L,” identifying it as a piece likely crafted by Henry Williamson Ltd. Based in Birmingham’s historic Jewelry Quarter, the firm was active from the late 1800s through the early 1900s and was known for producing finely crafted gold and silver pieces.
