Oscar-winner Julianne Moore steps into her first major campaign for Messika - and brings something the house hasn't had before: a glamour built entirely on substance.
March 30, 2026
On 30 March 2026, Parisian high jewellery house Messika formally announced Julianne Moore as its new global ambassador - a move the brand described as "formalising a bond long in the making." The first campaign visuals, featuring Moore in the house's new Moderniste collection, were released shortly after in April.

The relationship between Moore and Messika stretches back further than the announcement suggests. In 2018, she wore Messika's signature Move necklace on screen in Gloria Bell - and in October 2025, she attended the brand's 20th anniversary cocktail evening at the Frick Collection in New York, dressed in the Zebra Luhlaza high jewellery choker from the Terres D'Instinct collection. The ambassadorship, when it came, felt less like a signing and more like an acknowledgement of something already true.
The Moderniste campaign was shot against a black void by photographer Ezra Petronio, stripping away everything except the gold and the personalities of the women wearing it - Moore alongside model Irina Shayk.The collection draws from the clean geometry of 1970s Modernist architecture, and Moore's sensibility maps naturally onto it. "There is a purity to them that lets you see the jewellery, but also lets it move with your physicality. They are not so ornate that they feel separate from you. They feel like they belong," Moore said of the pieces.
Founder and artistic director Valérie Messika framed the casting in clear terms: "Julianne is the very epitome of modern allure - powerful, intelligent and deeply luminous. She has that rare presence that is both timeless and strikingly contemporary."
Moore currently also serves as ambassador for Bottega Veneta and watchmaker Movado - a portfolio that points to a consistent brand logic: houses that prize restraint, craft, and a certain refusal of noise. Messika, with its "diamonds in motion" philosophy, fits that world precisely. In Moore, it has found a face that doesn't compete with the jewellery - she simply wears it as though it was always hers.
