Late Georgian jewellery covers, by most British conventions, the period from roughly 1800 to the death of King William IV in 1837. The bracket spans the Regency proper (1811-1820), the brief reign of George IV (1820-1830), and William IV's seven-year reign that closed the Hanoverian succession. Stylistically the era is harder to bound than its dates suggest, because it sits between the cool Neoclassicism of the late eighteenth century and the romantic, narrative-driven jewellery that would dominate the second half of the nineteenth.

Materials and construction

The single most important technical fact of late Georgian jewellery is that it was made before the introduction of the rolled-gold and electroplating processes that would democratise the trade in the 1840s. Gold was alloyed and worked by hand, typically at fifteen, eighteen, or twenty-two carats, and silver was used as a setting metal for diamonds because contemporary smiths believed silver enhanced the appearance of white stones. The closed-back foiled setting, in which a thin sheet of coloured metal foil is laid behind the stone to amplify or correct its colour, is the period's signature technical mark; an open-back setting on a piece otherwise consistent with the era is generally a sign of later alteration.

Cut-down collets, cannetille (a fine wire-work technique imitating filigree), and repoussé chasing carried much of the decorative load. Cannetille rose to prominence after 1810 partly as a response to the gold shortages of the Napoleonic Wars, since the technique used very little metal. The term derives from the French for hand-spun gold thread used in embroidery, and the work has the same quality of fine, raised line.

Stones and motifs

Diamonds in late Georgian jewellery are almost exclusively old-mine cuts and rose cuts, set in silver-topped gold. Coloured stones included topaz from Brazil, amethyst, citrine, garnet (especially the deep red almandine and pyrope varieties), turquoise from Persia, coral, and seed pearls from the Persian Gulf and Sri Lanka. Emeralds and rubies appear but were comparatively scarce and tended to be reserved for important pieces.

Sentimental motifs proliferated. Lover's eye miniatures, painted in watercolour on ivory and set under rock crystal or glass, were exchanged as private tokens. Hair jewellery, in which a lock of a loved one's hair was woven into the back of a brooch or contained behind a glass-covered compartment, became widespread. Acrostic jewellery spelled words by the first letter of each stone, the most famous being REGARD (ruby, emerald, garnet, amethyst, ruby, diamond) and DEAREST (diamond, emerald, amethyst, ruby, emerald, sapphire, topaz).

Forms and conventions

Parures and demi-parures, matched suites of jewellery comprising tiara, necklace, earrings, and brooch, dominated court and formal wear. The girandole earring, with three pear-shape drops suspended from a central cluster, persisted from the eighteenth century. Riviere necklaces of graduated stones, often topaz or amethyst in foiled collets, were common day pieces. Cameos, both shell and hardstone, gained prominence after the Napoleonic excavations at Pompeii revived interest in classical antiquity, and the Empress Josephine's enthusiasm for the form helped spread the fashion across Europe.

Trade and identification

The British trade marked gold above the precious threshold but rarely marked silver settings used for diamonds, and many pieces consequently carry no hallmark at all. Authentication therefore turns on construction details: hand-finished collets with slight irregularities under magnification, the presence of foiling and closed backs, the texture of cannetille work, and the cuts of the stones. Pieces that appear too uniform, too symmetrical, or that show evidence of casting rather than fabrication are unlikely to be genuine.

The trade is comfortable identifying late Georgian work in three broad ways: the hardware (closed backs, silver-on-gold for diamonds, foil), the cuts (old-mine, rose, table), and the decorative vocabulary (cannetille, repoussé, sentimental motifs, classical revival). A piece that satisfies all three with consistent wear and patina commands a substantial premium over Victorian or later reproduction.
