Sarah Jessica Parker joins Astrea London to shape the future of lab-grown diamonds as Brilliant Earth deepens its partnership with Dr. Jane Goodall, weaving celebrity, activism, and sustainability into fine jewelry.
Sarah Jessica Parker has added a new facet to her career, stepping into the world of fine jewelry with Astrea London. The actress and fashion entrepreneur is partnering with founder Nathalie Morrison as joint spokesperson and creative collaborator, bringing her influence to a brand that calls itself a leader in the highest echelon of lab-grown diamonds.
The partnership will debut with a 12-piece collection later this year, including stones graded at D-IF, a level representing just 0.01 percent of the world’s diamonds. Each piece will carry certification from IGI, GCAL, and currently GIA. “Joining the business feels like a natural step — together, we are embracing the future of diamonds in a way that is both responsible and beautiful,” Parker said in a statement.
Astrea, founded in 2022, has built its reputation on producing only the top one percent of diamonds by quality. Its stones fall in the coveted D and E color range, VS2+ clarity. Expansion has been swift: the brand has opened in Provence, Windsor, and Kea Island, with three Dubai boutiques launching this fall, including a flagship at Mandarin Oriental Jumeirah.
Its collections are framed both by rarity and a stated commitment to social purpose, with part of the annual income going to educational and global initiatives. The company says it wants to lead the conversation “on how luxury can be a force for good.”
The announcement arrives just as another name in lab diamonds, Brilliant Earth, deepens its own role in ethical jewelry with its second collaboration with Dr. Jane Goodall. The limited-edition Jane Goodall Peace Medallion features a hand-engraved dove and olive branch, a nod to her lifelong advocacy for peace. The wider collection incorporates 99 percent repurposed gold and carbon-capture lab-grown diamonds.
“Jane Goodall embodies purpose, responsibility, and the power to inspire positive change,” said Beth Gerstein, Co-Founder and CEO of Brilliant Earth. “Creating jewelry that honors Jane’s extraordinary legacy, went beyond beautiful designs; we’ve created heirlooms that carry forward her message of hope and our collective power to transform the world.”
Goodall framed the collection as a call to action. “Everyone can make a difference, and we all can make choices that benefit the natural world,” she said. “This collection represents more than jewelry; it embodies the values we share and the future we can create together. When someone wears these pieces, they carry with them a commitment to protecting our natural world. They become part of the movement that demonstrates hope through action.” Ten percent of proceeds will support The Jane Goodall Legacy Fund, fueling conservation, education, and youth empowerment programs through Roots & Shoots.
The two announcements reflect how jewelry houses are increasingly pairing with cultural figures to bring lab-grown diamonds to the center of the conversation. The market itself is expanding rapidly: valued at $29.73 billion in 2025, it is projected to reach nearly $97.85 billion by 2034. Analysts estimate that by next year, one in five diamonds sold will be laboratory-created. Celebrity advocates have helped fuel that rise. Leonardo DiCaprio invested in Diamond Foundry, the parent of Vrai, while Pamela Anderson partnered with Pandora on its lab-grown line. Actress Madelaine Petsch has also embraced conflict-free stones, reinforcing their appeal among younger consumers.
The shift is disrupting traditional diamond economics. Rough mined diamond prices have dropped 34 percent in the last two years, while lab-grown equivalents have fallen more than 70 percent since 2020. But even as prices decline, demand continues to grow. In the U.S., over half of engagement rings sold now include lab-grown diamonds.⁵
Astrea London’s approach places Parker at the center of its creative evolution, while Brilliant Earth’s partnership with Goodall links jewelry to global activism. Both moves speak to what modern consumers increasingly expect: values as intrinsic as carat weight. And as Goodall noted, a value much more immeasurable: “When someone wears these pieces, they carry with them a commitment to protecting our natural world.”
