Nicky and Kathy Hilton launch customizable gold Mother’s Day jewelry collection

The strongest case for Mother’s Day jewelry is not another generic pendant, but a piece that can hold a name, a photo or a family memory. Nicky and Kathy Hilton’s new Theo Grace collaboration, Made to Treasure, leans hard into that idea with six core styles that include necklaces, bracelets, brooches and pins, all designed to feel more like keepsakes than throwaway accessories.

Launched Monday, April 6, 2026, the collection sits in an approachable gift range, from about $65 to $140 before customization. Theo Grace says the pieces come in gold and silver, with diamond and non-diamond versions, which gives the line a useful split between polished sentiment and price sensitivity. Gold changes the mood immediately: it reads warmer, dressier and closer to heirloom territory. Silver feels cooler and more casual, a better fit for someone who prefers understated daily wear. For a buyer deciding between the two, that metal choice may matter more than the motif.

The lineup includes a gold-plated brooch, a customizable oval photo necklace, an initial cube necklace and a locket, all built around the idea that personalization is the product. Theo Grace says the collection can be customized with personal photos, names and monograms, and the brand describes the designs as classic motifs in solid metals. That keeps the collection from feeling like novelty jewelry, especially in the locket and photo pendant forms, which already carry an old-school emotional charge.

The campaign, shot in London, was meant to capture the mother-daughter dynamic that drives the collaboration. Nicky Hilton called the pieces “walking love notes,” while Kathy Hilton said their tastes are naturally aligned and that time moves quickly as a family grows. Theo Grace says Nicky gravitates toward layered, delicate pieces, while Kathy prefers bolder, more classic statements, a contrast that helps explain why the collection stretches from subtle initials to more visible brooches and pins.

The label itself carries family weight: Theo Grace is named after Nicky Hilton’s daughters, Theodora and Lily-Grace, and Nicky has said this is her first time being an owner of a brand. With Lily-Grace, Theodora and Chasen also shaping her thinking and occasionally sitting in on business meetings, the collection feels less like a celebrity licensing exercise than a family archive turned into jewelry. For shoppers choosing between a standard ready-made gift and something personalized, that difference may be the whole point.
