Paris: Paris-based fine jewellery maison Messika has appointed Oscar-winning actor Julianne Moore as its new global ambassador, marking a significant moment as the brand celebrates its 20th anniversary.

The collaboration is anchored by a new campaign featuring Moore in the house’s latest Moderniste collection, designed by founder Valérie Messika. The campaign highlights a contemporary design language inspired by modernist architecture, with clean, graphic lines translated into octagonal bangles, rings, hoop earrings and necklaces crafted in white and yellow gold.

Through this partnership, Messika brings together its distinctive diamond aesthetic with Moore’s refined and expressive persona. The campaign positions jewellery as both a personal statement and a form of self-expression, reflecting the Maison’s evolving narrative around modern femininity.

Speaking on her association with the brand, Moore emphasized her long-standing fascination with adornment and the emotional connection people share with jewellery. She noted that while jewellery can play a role in defining character and identity, it also carries deeply personal meaning for the wearer.

The Moderniste collection campaign focuses on versatility and wearability, with pieces designed to be styled individually or layered for greater impact. The designs aim to strike a balance between minimalism and boldness, aligning with Messika’s signature approach of creating contemporary diamond jewellery that integrates seamlessly with the wearer.

Moore’s association with the maison builds on an existing relationship, as she has previously worn Messika creations on screen and at key global events. Her presence in the new campaign reinforces the brand’s positioning at the intersection of fashion, culture and fine jewellery.

With this appointment, Messika continues to strengthen its global visibility while marking two decades of design innovation and expanding its narrative around modern, design-led diamond jewellery.

Messika was founded in 2005 by Valérie Messika. Known for its contemporary approach to diamond jewellery, the brand blends minimalist design with everyday wearability, and has built a strong global presence with nearly 100 boutiques worldwide and over 500 multi-brand points of sale across more than 75 countries. It also has a growing e-commerce business.
