Mourning jewellery: Jet Brooch, 19th century.Starting in the late 18th century, Romanticism had a profound impact on the development of western jewellery. Perhaps the most significant influences were the public’s fascination with the treasures being discovered through the birth of modern archaeology, and the fascination with Medieval and Renaissance art. Changing social conditions and the onset of the industrial revolution also lead to growth of a middle class that wanted and could afford jewellery. As a result, the use of industrial processes, cheaper alloys, and stone substitutes, lead to the development of paste or costume jewellery. Distinguished goldsmiths continued to flourish, however, as wealthier patrons sought to ensure that what they wore still stood apart from the jewellery of the masses, not only through use of precious metals and stones but also though superior artistic and technical work; one such artist was the French goldsmith Françoise Désire Fromment Meurice. A category unique to this period and quite appropriate to the philosophy of romanticism was mourning jewellery. It originated in England, where Queen Victoria was often seen wearing jet jewellery after the death of Prince Albert; and allowed the wearer to continue wearing jewellery while expressing a state of mourning at the death of a loved one.
