Plique-à-jour (French for "letting in daylight") is a rare enamelling technique that creates stunning, translucent effects—like miniature stained glass.
While its origins trace back to the Byzantine period, it experienced a celebrated revival during the Art Nouveau era, particularly in the hands of French and German jewellers.
Designers such as Heinrich Levinger and René Lalique crafted extraordinary pieces that continue to define the style and artistry of the period today.
