Behind the Design: The Shell Necklace

A sculptural masterwork, the Shell necklace is an intricate reimagining of nature’s masterpieces. Artisans crafted the design by hand with a palette of custom-cut diamonds, platinum—and a mesmerizing freeform black opal of over 19 carats.

The Shell theme is inspired by an archival Jean Schlumberger masterpiece. Reworking its forms while preserving the design’s expressive spirit and intricacy, Chief Artistic Officer Nathalie Verdeille created breathtaking, innovative designs that pay homage to the iconic Schlumberger brooch.

The Shell necklace can be worn as four unique designs resulting from innovative hidden mechanisms that allow the shell motif to detach from the necklace. The top of the shell hinges open to reveal the striking black opal, which can also detach from the piece. A feat of extraordinary craftsmanship, Tiffany’s designers and artisans collaborated to bring this remarkably versatile creation to life.
“There is nothing more modern than pushing boundaries and creating with a passion to explore the unknown. This idea was, of course, close to Jean Schlumberger’s heart as well.”
