Art Deco — the period from roughly 1920 to 1935 — produced some of the most architecturally striking jewellery ever made. A century later, those same pieces are the most-collected, most-imitated and most-loved category of vintage jewellery on the market. Here is what makes the era so distinctive, and why it has aged better than any other.
A short originThe name "Art Deco" comes from the 1925 Exposition Internationale des Arts Décoratifs et Industriels Modernes in Paris. The exhibition celebrated a new approach to design — geometric, machine-age, modern, deliberate — in conscious rejection of the floral curves of Art Nouveau that had dominated the previous decades.
Three forces converged to create the style:
- The Russian Ballet's Paris seasons (1909–1929) — Diaghilev's dancers in vivid orientalist costumes electrified Parisian taste.
- The discovery of Tutankhamun's tomb (1922) — Egyptian motifs, lotus shapes, cartouches and scarabs flooded into design.
- The Machine Age — locomotives, ocean liners, the new architecture of New York skyscrapers (Chrysler Building, Empire State) — gave designers a new visual language of clean lines and stepped geometry.
1. Geometry
Art Deco pieces are built from geometric shapes — squares, rectangles, triangles, circles arranged in ordered patterns. Curves are minimised; symmetry dominates. A Deco brooch reads like a small piece of architecture more than a flower.
2. Calibre-cut coloured stones
Designers cut sapphires, emeralds and rubies into precise geometric shapes (squares, rectangles, half-moons) to fit into geometric settings. This "calibre cut" was a signature of the period — almost no jewellery before 1920 used coloured stones this way, and very little after 1935.
3. Diamond + onyx + platinum
The signature material trio:
- Diamond for sparkle and structure.
- Onyx for graphic black contrast.
- Platinum as the underlying metal — strong enough to hold delicate filigree, white enough to disappear behind the stones.
4. Filigree and openwork
Platinum's strength allowed designers to create delicate openwork patterns that feel almost weightless. Negative space is part of the composition — a Deco brooch is as much about what isn't there as what is.
5. Asian and Egyptian motifs
Lotus flowers, dragons, fans, pagodas, scarabs, cartouches — the period was fascinated with non-Western symbolic vocabularies. Cartier's "Tutti Frutti" pieces (carved emerald, ruby and sapphire combined in Mughal-inspired designs) define the high point.
6. Bold colour combinations
Sapphire blue with emerald green; coral red with onyx black; turquoise with diamond white. Combinations that earlier eras would have considered unsuitable became the period's signature.
7. Long lines
Deco jewellery emphasised verticality — long pendant earrings, long sautoirs (long necklaces sometimes over 1 m), bracelets that ran from wrist halfway up the forearm. The flapper silhouette of dropped waist dresses suited long jewellery beautifully.
The significant housesThe Deco period was the high era of fine jewellery houses still active today:
- Cartier — the period's defining house. Tutti Frutti, panthers, mystery clocks.
- Van Cleef & Arpels — the Mystery Setting (Serti Mystérieux) patented in 1933 hides all metal behind precisely calibrated stones.
- Boucheron — Place Vendôme jeweller, Egyptian-inspired works.
- Mauboussin — known for sapphires and emeralds.
- Tiffany & Co. — the American Deco house; Jean Schlumberger arrived in 1956 but the house's Deco pieces remain iconic.
- Lalique — primarily known for glass but also produced exceptional Deco jewellery.
- Fouquet, Sandoz, Templier — Parisian designers whose unsigned works are highly collectable.
- Sautoir necklace — long pearl or stone strand, worn looped or draped to the waist.
- Panel bracelet — wide band of articulated geometric panels, often diamond and onyx.
- Brooch — the most-produced Deco piece; geometric architectural designs in platinum.
- Cocktail ring — the term itself originated in this era, when women began drinking publicly during Prohibition and wore deliberately oversized rings for the occasion.
- Tutti Frutti — carved coloured stones in Mughal-inspired clusters.
- Tassel necklaces — cascading drops at the front of long necklaces.
- Calibre-cut emerald and sapphire bracelets — the most identifiably Deco bracelet shape.
Three reasons Art Deco never feels "dated":
- Architectural design reads as modern in any decade — geometry is timeless.
- Quality of construction was extraordinary — pieces from 1925 still close perfectly, settings still hold stones securely. Modern reproductions rarely match the original execution.
- The colour palette (black + white + jewel-tone accents) remains contemporary in fashion — Deco pieces work as easily with a modern silk dress as they did with a 1925 flapper costume.
- Authenticate carefully: reproductions exist. Look for period hallmarks (platinum 950 stamps, French eagle's head for 18k gold), construction characteristics (machine-cut diamonds with old-cut facet patterns), and provenance documentation.
- Buy from reputable dealers: auction houses (Christie's, Sotheby's, Bonhams) and established antique jewellers. Avoid eBay for valuable pieces.
- Check condition: filigree platinum is delicate; look for repaired sections, missing stones, replaced clasps.
- Get an appraisal: for any piece over £2,000 / $2,500.
- Consider unsigned pieces: exceptional unsigned Deco work can offer the same beauty as Cartier or Van Cleef at a fraction of the price.
Many contemporary fine jewellery houses still produce Deco-inspired collections — Tiffany's "Atlas" line, Cartier's archive reissues, Boucheron's Quatre. The original is always more valuable, but a well-made modern Deco-inspired piece offers the aesthetic at lower cost and without the fragility risk.
FAQHow can I tell genuine Art Deco from Deco-revival?
Old-cut diamonds (transitional cut, asscher cut) point to the original era; modern brilliant cuts indicate revival or replacement stones. Hallmarks are decisive — pre-1935 European platinum work usually has identifiable hallmarks specific to the period.
Is Art Deco jewellery valuable?
Highly so. Signed Cartier and Van Cleef pieces from the period regularly achieve six-figure prices at auction. Unsigned fine pieces from the same era are also collectable but at more accessible price levels.
Can I wear Art Deco pieces daily?
Yes, with care. Platinum filigree is delicate — avoid hard impact. Annual professional inspection is wise for any vintage piece in regular wear.
