Nicky Hilton Rothschild Launches Theo Grace Mother's Day Jewelry Collection

When Nicky Hilton Rothschild built a jewelry brand around her daughters, she didn't expect the elder one to eventually pull up a chair. Lily-Grace Rothschild, now around 10 years old, has been sitting in on Theo Grace brand meetings, making the company's founding premise literal: this is a business built by a mother, for mothers, with family woven into every detail.

The brand's Mother's Day collection launched today, April 6, with several weeks of lead time before the holiday arrives in May. The timing matters: Americans spend roughly $34 billion on Mother's Day annually, and personalized jewelry has become one of the category's most reliable performers. The Theo Grace collection arrives with celebrity credentials, a multigenerational campaign, and a price range spanning $110 to $750, covering the gap between "first fine jewelry piece" and "serious milestone gift."

The collection follows the format Hilton established at Theo Grace's debut on June 24, 2025, at the SeaGlass Carousel in New York City: necklaces, bracelets, rings, and earrings customizable with names, initials, monograms, dates, or photographs. For a new mom or a grandmother, pieces in the $110 to $250 range offer personalized lockets and nameplate-style designs without requiring a major outlay. The $250 to $500 tier suits the fashion-forward mother who knows jewelry and wants something with staying power. Above $500, up to the $750 ceiling, the options skew toward more substantial customized pieces that read as investment gifts rather than seasonal tokens.

Kathy Hilton, Nicky's mother and a central figure on The Real Housewives of Beverly Hills, appears in the Mother's Day campaign. The two have collaborated before: Kathy and Nicky partnered on a Theo Grace collection at BravoCon inspired by Kathy's Bravo one-liners, including a necklace built around her "Hunky Dory" catchphrase. Kathy's presence in the Mother's Day campaign extends that dynamic into something the brand can use as a direct pitch: a daughter buying for her mother, a mother buying for her daughter, each purchase anchored in a real relationship.

That specificity is the point. The brand's name comes directly from Nicky's two daughters: Theodora, nicknamed Theo, and Lily-Grace, whose middle name supplies the second word. Hilton described her goal as creating "a value-driven brand with customized pieces to commemorate important people, dates, or moments," and the brand's stated ethos is "a movement to bring heart back into the art of gifting."

Backed by the Tenen Group, Theo Grace represents Hilton's return to jewelry after roughly 15 years: she released an Art Deco-inspired line in 2010 before spending the next decade and a half on apparel, handbags, and footwear collaborations. She studied fashion at both Parsons School of Design and the Fashion Institute of Technology, and has built collaborations with Samantha Thavasa, Linea Pelle, Tolani, and, most recently, Australian designer Rebecca Vallance. Theo Grace is her first fine jewelry line, and with Lily-Grace now attending business meetings, the succession plan may already be in motion.
