Tortoiseshell Box Containing A Miniature Portrait Of Anne Nicole Voullemier De Saint Vincent De Paul

Large tortoiseshell box with a large miniature, likely set in ivory, inlaid and surrounded by a silver border.
This miniature is signed “Voullemier,” a confirmed signature of Anne Nicole Voullemier (1792–1882)* and, I believe, depicts Saint Vincent de Paul holding a crucifix; this painting measures 8.2 cm x 6 cm at face, and it shows signs of soiling as visible in the latest photos, which were taken without the glass after disassembly.
The date appears to be 1855.
The box itself has been restored, as can be seen in the photos.

*Born in Ampilly-le-Sec on July 4, 1792.
She exhibited at the Paris Salon from 1819 through 1850.

She was awarded a third-class medal in 1835 and a second-class medal in 1845. The director of the royal museums awarded her a gold medal on behalf of the king.
Moved by the delicate beauty of one of her works, Pauline de Flaugergues dedicated a poem to her.
