Stuller adds lab-grown center stones and lighter bridal styles at JCK Las Vegas

Stuller leaned harder into shape than size at JCK Las Vegas, unveiling lab-grown center stones in elongated ovals, old mine elongated cushions and octagons as it chased the bridal shopper who wants something more distinctive than a round solitaire. The assortment also brought the old mine elongated cushion into natural diamond, a telling move for a silhouette that has gained momentum, especially after Taylor Swift’s August 2025 engagement to Travis Kelce pushed vintage-coded cuts further into the spotlight.

The new fancy shapes were offered in both faceted and step-cut styles, giving retailers a wider range of looks to sell to brides who want either more sparkle or a cleaner, architectural face-up. Stuller also expanded demi-fine metals and lighter band styles, positioning the collection at a lower price point without abandoning the polished finish of fine bridal jewelry. The company describes demi-fine as using affordable metals such as silver and gold layering techniques to create that fine-jewelry effect at more accessible cost.

That pricing logic matters because the lab-grown category is no longer a niche experiment. The Knot’s 2026 Real Weddings Study found lab-grown center stones accounted for 61% of engagement ring purchases for couples married in 2025, up 239% since 2020. Stuller’s latest assortment fits squarely into that shift: the company has been building out lab-grown offerings for several seasons, from its first dedicated Lab-Grown Diamond Jewelry catalog in 2024, which included more than 1,500 jewelry items and more than 650 loose lab-grown diamond options, to its 2025-2026 Fine Jewelry catalog, which added 1,000 new styles and more lab-grown diamond jewelry.

Emily Graffagnino said lab-grown diamond jewelry has brought “excitement and opportunity” for consumers, and that sentiment now reads less like optimism than market reality. Stuller, which calls itself the #1 supplier of fine jewelry, findings, mountings, tools, packaging, diamonds and gemstones for retail jewelers, said its 2026 JCK showcase included more than 20 new and expanded selling systems designed to help jewelers manage inventory while offering fast-moving styles and strong value.

The most revealing detail may be the color story. Alongside the center-stone push, Stuller added colored lab-grown gemstones in magenta, periwinkle and mauve, widening the palette for shoppers who want bridal pieces with a little more personality. In other words, the modern engagement ring is moving beyond a single canonical look, and Stuller is betting that labor-saving inventory, vintage-coded silhouettes and lab-grown value will keep that evolution moving.
