A 19th century enamel and diamond set memorial miniature pendant/brooch, the oval miniature painted with the portrait of a lady wearing a turban, pearl necklace and earrings, possibly on ivory, to an openwork foliate scroll frame with graduated old and rose-cut diamonds in foiled closed-back settings, heightened with blue enamel and old-cut diamond set bosses to the cardinal points, the reverse with glazed hairwork compartment to an opalescent enamel ground, brooch fitting possibly later, length 6.45cm
Dust/dirt residue and occasional light scuffs to miniature panel, scuffs and nicks to glazing, length of panel 3.8cm. Diamonds have a typically greyish appearance with variable colour and clarity, some stones with chips/fractures, but give an overall lively appearance. Some of the foil backing has patchy discolouration and occasional stones may be later replaced. Largest old-cut diamond weight approx. 0.04ct. Scuffs and nicks to blue enamel bosses. The opalescent enamel to the reverse is fractured and crazed and the hairwork compartment has dust/dirt residue. General wear, scratches, scuffs, nicks and chips to mount, commensurate for age and use, with patchy tarnishing and rubbing to engraved decoration on reverse. The mount is untested but appears to be a silver and gold combination. The brooch catch requires repair/adjustment. Gross weight approx. 30gm.
