Tiffany & Co. Introduces a New Icon: The Sixteen Stone Solitaire Diamond Ring

Some designs earn the word icon before they’ve been around long enough to prove it. Others carry it across decades and still feel entirely current. The Sixteen Stone collection is the latter—and today, Tiffany & Co. gives it its most significant evolution yet.

The Sixteen Stone solitaire diamond ring arrives as the boldest new expression of a motif that Jean Schlumberger first conceived in 1959. Originally designed as a wedding band, the Sixteen Stone’s intricate X pattern—reminiscent of a sewing cross-stitch, creating the illusion of diamonds held delicately together by precious metal threads—has become one of Tiffany’s most enduring and recognizable signatures. The X motif symbolizes the strength found in love, and in its newest form, it frames something even more substantial: a solitaire diamond that transforms the collection’s quiet symbolism into an unmistakable statement.

The ring features a center diamond in 2 to 2.99 carat sizes, set within a distinctive basket of X-shaped prongs—an original design that echoes the cross-stitch inspiration at the heart of the collection. Six hand-applied 18k yellow gold X motifs stitch together diamonds along the platinum band, the contrast between the two metals creating a visual tension that is as technically demanding as it is beautiful. Platinum and 18k yellow gold together represent one of the more challenging material combinations in fine jewelry, and Tiffany’s execution here is a clear demonstration of the house’s mastery of both.

The solitaire doesn’t arrive alone. The launch also introduces Sixteen Stone all-metal rings for the first time—a significant first for the collection—alongside five new styles within the broader Sixteen Stone universe. Together they expand Tiffany’s Love & Celebration category in both directions, from high jewelry pieces to refined everyday expressions, offering something for every occasion and every hand.

The ring’s roots trace directly to Jean Schlumberger, whose work for Tiffany & Co. redefined what jewelry could be in the 20th century. Born in 1907 into a family of textile manufacturers in Alsace, France, Schlumberger spent his life drawing inspiration from garments, couture, and the artistry of woven fabrics. He joined Tiffany in 1956 and spent decades transforming those textile-inspired forms into sculptural, bejeweled works of art. His signature use of woven gold—with and without platinum—remains one of the house’s most defining design codes. The Sixteen Stone solitaire honors that legacy while advancing it for a new generation.

Designed with versatility at its core, the new solitaire ring aligns proportionally with existing Sixteen Stone pieces, allowing for stacking and pairing across the collection. Universal in its appeal, the Sixteen Stone collection has always transcended traditional categories—suited for all genders and occasions—and the solitaire is no exception. It is, as Tiffany puts it, the collection’s most significant evolution to date.
