For a time after The Terror, in Revolutionary France, we find portrait miniatures done with political statements build in. Revolutionists often hold a small flower linked to their support of the rebirth of France, and mourning Royalists (Loyalists) had portraits done with the slash of blood red around necks, shoulders, signifying their mourning and support and remembrance of those who met their rude end at the guillotine. The 1780s saw many deaths of loyalists and royalists, and it is likely this woman lost members of her family. Images tell stories if we just know the language.
Very good to excellent without damage to report, really. The frame is the 1700s to early 1800s lathed wood. A matronly lace bodice/collar which would cover the bodice showing above her French Empire styled dress. I would date it c.1790s-1810s. Very fine 3/4 seated portrait showing her holding a book, her seed pearl tiara and long gold watch chain, bodice buckle typical of her time and station
