An important innovation in jewellery making during this era was the technique of producing cameos with hard pastes called black basalt and jasper. English pottery manufacturer Josiah Wedgwood is responsible for this important contribution to jewellery making. Cameos and brooches with classical scenes were fashionable during this period. Pearls and gemstones continued to be used in brooches, but were less popular than before. The beginning of the French Revolution halted the manufacture and demand for opulent jewellery. Late modern brooches The late modern era of jewellery covers the period from 1830 to 1945. The major jewellery styles of this period are: Victorian (1835–1900), Art Nouveau (1895–1914), Edwardian (1901–1910) and Art deco (1920–1939). Victorian This period was named for Queen Victoria of the United Kingdom, who reigned from 1837 to 1901.

Human hair was encased within the brooch or braided and woven into a band to which clasps were affixed. Art Nouveau The Art Nouveau period of jewellery spanned a short period from 1895 to 1905. The style began in France as a reaction to the heavy, somber jewellery of the Victorian era. Innovative, flowing designs were now in fashion along with nature, flowers, insects and sensuous women with flowing hair. The jewellery style was fashionable for fifteen years, and ended with the beginning of World War I. Edwardian The Edwardian era of jewellery (1901–1910) began after the death of Queen Victoria. This period marked the first time platinum was used in jewellery. Because of platinum's strength, new jewellery pieces were created with delicate filigree to look like lace and silk. The main gemstones used in brooches were diamonds, typically with platinum or white gold, and coloured gemstones or pearls. Platinum and diamond brooches were a common brooch style. Small brooches continued to be fashionable. Popular brooch forms were bows, ribbons, swags, and garlands, all in the delicate
