Madison Keys, Brilliant Earth’s first athlete brand ambassador, has a new curated jewelry collection, which also includes a new design she helped create.
San Francisco, Calif.—Brilliant Earth has launched a new curated jewelry collection alongside its newest brand ambassador Madison Keys, just in time for the U.S. Open.
The partnership, announced last month, marked the jewelry retailer’s entry into the world of professional sports with its first athlete ambassador.
“This collaboration is all about strength, resilience, and personal growth, designed to be worn on and off the court,” said the company.
The new collection features a curation of Keys’ favorite Brilliant Earth jewels, including tennis jewelry, diamond studs, stackable rings, hoops, an evil eye pendant, and an Aquarius medallion.
“I chose to partner with Brilliant Earth because it felt like the most organic, natural partnership. And I love expressing myself through jewelry,” said Keys.
“One of the biggest parallels I see between tennis and jewelry design is how important the little details are.”

“One of the biggest parallels I see between tennis and jewelry design is how important the little details are.”
There is also a new piece, a limited-edition medallion co-designed by the tennis champion.
Keys co-designed this diamond medallion, including elements that tell her story.
The two-sided Madison Keys diamond medallion is crafted in 14-karat yellow gold with diamonds and retails for $1,350.
On one side, it features a tennis racket motif with a pavé diamond lucky clover and nine diamonds (Keys’ lucky number) along the outer edge.
The reverse side features symbolic embossed charms, including a horseshoe, sun, moon, heart, and key.
The medallion’s reverse side features symbols and good luck charms.
“There’s a lot of meaning in every single aspect of this design,” said Keys.
The horseshoe is for a touch of luck, said Keys, while the celestial symbols were chosen because Keys and her sister are “obsessed with suns and moons.”
“There’s a lot of meaning in every single aspect of this design. It is my way of telling my own personal story,” said Keys.
Keys made an appearance in New York City over the weekend at a Brilliant Earth-themed ice cream truck, serving up sweet treats and other merch.
She is set to play in the first round of the singles tournament at the 2025 U.S. Open today.
