Miniature Mother-of-pearl Portrait Of An Unknown Man, Circa 18th Century

This is a finely carved mother-of-pearl portrait of an unknown man in profile, dating from the 18th century. The bust is meticulously mounted on a guilloche metal support and is protected by oval glass set in a gilt border. The whole is mounted in a black wooden frame. The portrait is carved with great detail and realism, testifying to the skill of a true master. I have not found comparable pieces on the antique market. Carving a realistic portrait in mother-of-pearl is an incredibly difficult task, much more difficult than using paint. This is a unique miniature, and I believe it was originally in another frame. Dimensions: The frame measures 10cm x 12.5cm, while the portrait itself measures 6.5cm x 5.2cm. Condition: The frame has scratches and paint scuffs consistent with its age. The mother-of-pearl portrait is in perfect condition. Please study the attached photos carefully as they are an integral part of this description.
