Paris-born diamond jewelry maison Messika has announced that Academy Award–winning actress Julianne Moore has been named its new Maison Ambassador. Moore will appear in upcoming global campaigns and key projects around the world, embodying the values and spirit of the maison.
Known for its innovative concept of “moving diamonds,” Messika sees the partnership with Moore as a celebration of modern femininity—one defined by freedom, confidence, and individuality. Her intelligence, strength, and refined elegance closely reflect the contemporary vision of womanhood that the brand represents.
The relationship between Messika and Moore predates this official appointment. In October 2024, the actress attended the opening of the Messika boutique on Madison Avenue in New York. Her poised presence and understated elegance left a lasting impression, symbolizing the spirit of the maison.
Valérie Messika, founder and artistic director of the brand, commented on the collaboration: “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. From the moment we first met, the connection was immediate. Julianne speaks in emotion and light. As do our diamonds.”
A Connection Through Film
The relationship between Julianne Moore and Messika has also appeared on screen. In the 2018 film Gloria Bell, directed by Sebastián Lelio, Moore wore Messika’s iconic Move necklace. Featuring sliding diamonds as a signature design element, the collection is widely recognized as one of the brand’s most emblematic creations.
Founded in Paris in 2005 by Valérie Messika, the maison reimagines traditional diamond jewelry with a contemporary approach. Born into a family of diamond dealers, Messika combines exceptional craftsmanship and high-quality stones with fashion-forward design.
Today, the brand continues to expand globally and enjoys strong support from celebrities and fashion figures alike. In recent years, Messika has also staged high jewelry runway shows during Paris Fashion Week, presenting a unique intersection of jewelry and fashion. The brand entered the Japanese market in 2020 and currently operates nine directly managed boutiques across the country.
