The finely detailed brooch was made & signed, W.C.M., by silversmith William C. Manton of Hylton St in Birmingham, England, in either 1885 or 1893. (The date letter is hard to distinguish. See last few photos of hallmarks on back of pendant & Birmingham date mark chart.)
This is a unique, AH design and a one-of-a-kind blend of art & history. Both On Trend & classic, this necklace is a timeless statement piece & future heirloom.
