- Camille Kostek fronts Brilliant Earth's new "Seaside Charm" jewelry collection for summer 2026.
- The coastal-inspired charm collection features sand dollars, seashells, crabs, and pearls.

- This adds to Kostek's growing list of 2026 brand partnerships beyond modeling and TV hosting.
Sports Illustrated Swimsuit alum and TV host Camille Kostek is the new face of Brilliant Earth’s Seaside Charm Collection, a coastal-inspired jewelry line featuring sand dollars, seashells, crabs, and pearls.
Brilliant Earth said Kostek “perfectly embodies the collection’s playful, seaside spirit,” dressing her in four new charms for the warmer months ahead.
This marks Kostek’s first run with the brand, known for engagement rings and sustainable sourcing. The company celebrated its 20th anniversary last year and says it’s “committed to one idea: delight in the details.”
This is a fitting fit for Kostek, who recently teased the “sun kissed season” ahead on Instagram, leaning into her beachy, playful aesthetic. The campaign follows a busy stretch for Kostek’s brand resume, which includes turns with Victoria’s Secret and her own jewelry lines with Dune Jewelry.
She joins a growing wave of stars fronting jewelry campaigns this year: Jessica Alba recently became the face of Gabriel & Co.’s Love, Intention collection, while Emily Ratajkowski and her son Sylvester starred in Chanel’s latest jewelry push.
Takeaways
This deal taps right into Kostek’s brand: beachy, fun, and approachable. Brilliant Earth isn’t picking a one-note model, they’re betting on someone with an established lifestyle following who can sell “everyday luxury” rather than just red-carpet glamour. It also signals jewelry brands are increasingly leaning on personality-driven campaigns over purely aspirational ones.
Does this partnership open the door to a longer-term Kostek x Brilliant Earth relationship? Could this campaign boost Brilliant Earth’s profile with a younger, lifestyle-driven audience?
