Art Deco Jewelry
Art Deco jewelry belongs to the years between the wars — roughly 1920 to 1939 — and it broke deliberately with everything before it. Out went the garlands and lace of the Edwardian years; in came the straight line, the step, the chevron, and the hard contrast of black against white. The 1925 Paris exhibition that gave the style its name set the pattern, and jewelers translated architecture, machinery, and the art of Egypt, Africa, and the Far East into rings, bracelets, and pendants of strict geometry and confident color.
The materials announce it. Onyx against rock crystal, coral against gold, enamel in saturated blocks, and diamonds cut and set to flash in lines rather than clusters. Platinum and white gold carried the finest work, their settings drawn nearly invisible. At the same moment, Bohemia's glass workshops — the Czech makers above all — produced carved and molded glass jewelry of real artistry: peacocks and flowers cut into colored glass, set in gilt filigree, and sold across Europe and America. Deco costume jewelry is not a lesser imitation of the fine work; it is the same design language, made for a wider world, and the best of it is collected as such.
Rings show the period at its clearest: white gold filigree galleries pierced like lace around a single colored stone, three-stone and panel rings in stepped shoulders, and cabochons of onyx, jade, and coral in polished frames. Long necklaces, sautoirs, and station bracelets spaced their stones at intervals; pendants hung carved glass and crystal where an earlier age would have put a cameo. Marcasite — tiny pyrite crystals glittering in silver — gave evening sparkle at a fraction of diamond prices and was set by the thousand in Deco patterns.
Genuine Deco jewelry is dated by its construction as much as its look: hand-pierced filigree, milgrain edges, stones cut to the older fashions, and marks in the French, German, and Czech conventions. At Royal Regency every Deco piece is researched before it is listed — glass described as glass, stones as they test, and revival pieces in the Deco manner distinguished from jewelry of the period itself, so the geometry you buy is the geometry that was made.
Frequently asked questions
What years are Art Deco jewelry? The style runs from about 1920 to 1939, taking its name from the 1925 Paris Exposition Internationale des Arts Decoratifs. Its jewelry is geometric and architectural — straight lines, steps, and bold contrasts — where the Edwardian work before it was lacy and curving.
What materials are typical of Art Deco jewelry? Platinum and white gold, diamonds, onyx, rock crystal, coral, jade, and enamel in the fine work; carved and molded glass, marcasite, and gilt metal in the costume work. Strong color contrast — especially black and white — is the period's signature.
What is Czech glass jewelry? The glass workshops of Bohemia, in modern Czechia, made molded and carved glass jewels — pendants, necklaces, and brooches in rich colors, often with figural designs like the peacock. Sold worldwide in the 1920s and 1930s, the finest Czech glass is now collected in its own right.
What is the difference between Art Deco and Art Nouveau? Art Nouveau, earlier, flows — whiplash curves, insects, and women with streaming hair. Art Deco is its opposite: symmetry, straight edges, and geometry. A piece that curves belongs to the earlier world; a piece built of steps and angles belongs to Deco.
How can you tell a genuine Deco piece from a revival? Period construction is the test: hand-made filigree, old-cut stones, milgrain worked by hand, and period hallmarks. Revival jewelry in the Deco style is often cast heavier, with modern stones and modern catches — and an honest listing, like every one of ours, says which it is.
