Cartier Descendant Jean Dousset on 2026 Engagement Ring Trends and Lab-Grown Diamonds

Jean Dousset laid out a clear break with convention on the Who What Wear podcast with host Bobby Schuessler: the designer and Cartier descendant has decided to use only lab-grown diamonds in his bespoke engagement work, arguing plainly, “We are recognizing that these are two diamonds. They look the same, they behave the same, they just were created differently. That’s it.” Dousset, who has made one-of-one engagement rings for clients including Eva Longoria and Paris Hilton, framed the shift as a practical and aesthetic choice during the episode’s "The Pivotal Shift: Lab-Grown Diamonds" segment.

His brand experience is built around custom commissions and in-person appointments; showrooms in SoHo, New York, invite private visits so clients can “experience designer lab diamonds firsthand,” a detail Dousset’s team emphasizes in promotional booking copy. That emphasis on touch and finish matters when a maker with Dousset’s lineage - identified on the program as a great-great-grandson of Louis Cartier - is translating historic standards of cut, symmetry, and setting into stones that are chemically and optically identical to mined gems.

The wider market around 2026 is splitting into distinct visual directions that echo Dousset’s move. The Zoe Report’s rundown of top trends highlights a revived appetite for yellow diamonds, specifically “fancy light yellow stones in unusual shapes, such as radiants or elongated cushions,” Jessie Thomas says, while Rachel Boston notes that these stones “bring warmth, depth, and character to a design.” Examples named in that survey - the Shield Triple Trumpet Bezel Set Yellow Diamond Engagement Ring and the Classic Winston Oval-Shaped Yellow Diamond Ring - make clear why bezel work and warm yellow palettes are being chosen to differentiate bespoke pieces from the ubiquitous white-stone look.

Sculptural bands are another declared trend. Kegan Fisher of Frank Darling registers “an uptick in asymmetrical and curvier designs, as well as thicker bands overall,” and Jillian Sassone of Marrow Fine describes “chunkier, sculptural gold bands” that add weight and presence. The Zoe Report’s product examples - Sculptural Waves Wedding Ring and The Chevron Band among them - show how designers are using gold massing and profile to make the ring itself read as a statement rather than as mere setting.

Technical shifts in metal choice and facet architecture reinforce these shifts. Megan, a GIA gemologist presenting on Winston Gems and Jewellery, points to a return to silver or white metals, noting the price of gold per ounce is sitting at around $4,400 USD as a commercial pressure pushing buyers toward white-metal classics. She also forecasts bolder cuts for lab-grown stones - trillion, portrait, shield, and a “loen” shape - and says very large lab diamonds, two to three carats or larger, are increasingly being cut in Portuguese or Jubilee styles to maximize fire.

Taken together, Dousset’s public adoption of exclusively lab-grown diamonds, the Zoe Report’s yellow-diamond and sculptural-band callouts, and Winston Gems’ observations on metal prices and novel cuts outline 2026 as a year in which provenance, finish, and silhouette matter more than origin. For collectors and couples, that means choosing between a warm fancy yellow set in a trumpet bezel, a heavy sculptural gold band, or a white-metal ring set with an unusually cut, multi-carat lab diamond — each decision now signals not only taste but a stance on the material itself.
