VICTORIAN memorial ring in gold with black enameling marked "SH Chamberlaine Ob 23AUG1866" around the outside and engraved inside, size 7-1/2. Another ring similar to this can be seen in "Jewels & Jewelry" by Clare Phillips on page 140-3 and in Becker's "Antique & Twentieth Century Jewelry" on page 54,.This material for making cameos was invented by James Tassie late 18th century.The blue coloring at 3 o'clock on the ring is probably a manufacturing error at the time it was made since the blue color is also under the top layer of the white cameo, seen from the side. Hallmarks on the band are crown 375 tiger face and cursive "D" maker's mark "B G", band tests 10k, front tests 14k, so I am thinking it is possible that he band may not be original to the ring.Stones in the rings could also be set in a silver head with a karat gold band and rose cut diamonds, all typical of this time period.
