Piaget Sunlight

The sun as a disc of gold rays, each segment engraved, brushed or polished, around a halo of diamonds.

La Côte-aux-Fées, the Jura village where Piaget was founded in 1874, is where the house starts the journey behind Piaget Sunlight, which ends on the Riviera; its sun is a disc of gold rays, engraved, brushed or polished, ringed by diamonds around a centre of turquoise or malachite. Cartier's Grain de Café is a seed, not a star: Jeanne Toussaint's coffee bean of 1938, cast round and grooved in gold, gathered in clusters and edged with diamonds since 2023.
