These butterfly earrings are typical of the cut steel goods exported from France to much of Europe and America in the second half of the nineteenth century. The flourishing trade was bolstered by the need for jewellery to wear during periods of secondary mourning (an interim period between full and semi-mourning in the Victorian era) as well as by fashionable status. In London in 1882 it was reported that steel butterflies had begun to perch on bonnets.
