Nicky and Kathy Hilton Design Personalized Jewelry for Mother's Day

Nicky Hilton built her jewelry brand, Theo Grace, around a simple conviction: the best pieces carry someone's story inside them. Named after her daughters Theodora and Lily-Grace, the brand debuted in June 2025 on a foundation of customization, engraving, and photographs pressed into gold and silver. For Mother's Day, she brought her mother into the design process, and the result, the "Made to Treasure" capsule collection, launched April 6 with Kathy Hilton as both collaborator and campaign face.

"Working on the Theo Grace Mother's Day collection with my mom was so much fun," Nicky told E! News. "We laugh so much when we work together." That warmth is baked into the collection itself: six core styles spanning necklaces, bracelets, brooches, and a pin, each available in silver or gold plating with diamond and non-diamond versions, priced from $65 to $140 before customization add-ons.

Every piece in the Made to Treasure line can be personalized with photographs, names, monograms, or engraved messages, which makes the range unusually flexible for gifting across generations. The Keepsake Oval Photo Necklace, one of the collection's anchor styles, is available with an optional 0.10-carat diamond accent and fits equally well as a first Mother's Day gift for a new mom or a milestone present for a grandmother. Kathy Hilton singled out the Sweetheart Brooch, a delicate bow-shaped piece with a subtle diamond, and the Heritage Monogram Pin as personal favorites, both of which lean into the kind of classic, understated elegance she has long worn herself.

Nicky's own pick is the Heart Handwritten Necklace. "One of my favorites is the heart handwritten necklace where you can print your children's artwork, a nickname, a date, birthday," she explained. For a grandmother receiving one from grandchildren she rarely sees, or a new mother holding her first child's drawing, that kind of specificity is what separates a keepsake from a trinket.

"I often say Theo Grace jewelry is like walking love notes," Nicky said. "These customizable pieces make you feel special, loved and blessed, as well as stylish and beautiful." Kathy, who has watched her daughter build a family of three children alongside entrepreneur James Rothschild, offered her own perspective on the urgency behind pieces designed to outlast the moment: "You better enjoy every second of it."

The $65 entry price makes the collection one of the more accessible personalized fine jewelry options ahead of Mother's Day, particularly compared to Theo Grace's broader catalog, which runs to $750. For anyone trying to give something that won't end up in a drawer by June, the combination of a recognized name and genuine customization depth is what distinguishes it from a standard gift guide staple.
