Rare Victorian black enamel and 18 carat gold ring, the black enamel set with diamonds that spell ‘In Memory Of’ in italic script. 
Fully hallmarked for London 18 carat 1872.
I’ve not seen a ring like this before. A real beauty. The diamonds are white and sparkly, the enamel all original, and applied 3/4 of the way round the band.
