Blue Book 2025: Sea of Wonder

Urchin

The Urchin chapter strikes a harmonious balance between naturalistic and surrealistic elements. Urchin designs showcase incredible Fancy Intense Yellow diamonds set in loops of 18k yellow gold ‘rope.’ One impressive necklace features a Fancy Intense Yellow Diamond of over 18 carats accented by yellow and white diamonds.

Nature’s Textures

This chapter is inspired by the iconic motifs of Jean Schlumberger, one of the 20th century’s most gifted artists, including his twisted gold ‘rope’ and textile-inspired themes. This detail is featured in both his iconic 1961 sea urchin-inspired table clock (left) and throughout the new Urchin designs.

By the Numbers

Artisans crafted the Urchin ring over a span of approximately 200 hours, setting the 18k yellow gold and platinum design with a Fancy Intense Yellow diamond of over 12 carats and 14 white diamonds.

‘The Sea of Wonder collection is designed to echo the fluidity of the oceans and the graceful movement of their inhabitants. Many pieces in this collection are articulated, featuring intricate structures that require remarkable engineering expertise. We refined the shapes and mechanisms repeatedly until we achieved the perfect fluidity and movement within each piece.’
