Claes Ekeblad d.y. (1708-1771) * Carl Fredrich Brander (1705-1779)

The picture has something of this: people, necklace, portrait, royalty, Renaissance, veil, jewelry, wig, wear, cape, queen, fame, sash, lid.
Perhaps it’s a close up of a painting of a man in a white suit with a black and gold trim around his neck and a star.
