Plique-à-Jour: The Light-Filled Art of Transparent Enamel
Plique-à-Jour: The Light-Filled Art of Transparent Enamel
Plique-à-jour is one of the most mesmerising and technically demanding enamel techniques ever developed in jewellery. The name is French for “letting in daylight”, and that is precisely what defines it: translucent enamel suspended without any metal backing, allowing light to shine through like miniature stained-glass windows.
What Exactly Is Plique-à-Jour?
Unlike traditional enamel, which is fused onto a metal surface, plique-à-jour enamel is fired within tiny open cells—often made from gold or silver—before the supporting base is removed. The result is a delicate web of metal filled with luminous, glass-like enamel that glows when light passes through.
It is notoriously difficult to execute. Each cell must be filled and fired separately, and the enamel can crack or collapse at any stage. This difficulty is precisely what makes surviving antique examples so valuable.
When Did It Become Popular?
Your instinct is spot on. While the roots of plique-à-jour stretch back as far as the Byzantine and Russian workshops of the Middle Ages, the technique’s golden age was from the late 19th century to around the mid-20th century.
More precisely:
-
c. 1890–1910 – Art Nouveau peak
This is the era most associated with plique-à-jour. Jewellers such as René Lalique, Eugène Feuillâtre, and the workshops of Fabergé used the technique to create ethereal butterflies, dragonflies, floral motifs, and mythological figures. These pieces are now among the most coveted jewels of the period. -
1920s–1930s – Continued but reduced use
The Art Deco period favoured bolder stones and geometric lines, so plique-à-jour became less central but was still used for refined, high-craft pieces. -
1940s–1950s – The last flourish
As tastes modernised and production costs rose, the technique essentially faded from mainstream jewellery. It survived only in specialist workshops and artisan studios.
So, while plique-à-jour certainly appears from 1890 onward, its major era of popularity was roughly 1890–1910, with artistic echoes extending into the 1950s — very much in line with your own assessment.
Why Collectors Love It
For collectors, plique-à-jour represents:
-
exceptionally high craftsmanship,
-
fragile artistry that survived against the odds,
-
and the dreamy, otherworldly beauty of Art Nouveau.
Good examples remain rare, high-value, and deeply admired by lovers of historic jewellery.
