Aryna Sabalenka's 12-Carat Oval Diamond Ring Comes With a Playful Twist

When social media personalities Broadcast Boys put Aryna Sabalenka through a trivia quiz about herself at the Miami Open, she arrived at the correct answer almost instantly. How many carats is the oval-cut diamond Georgios Frangulis placed on her finger in March? "12," she said. Then came the follow-up that turned a sports moment into a jewelry headline: "No, I requested 14 but I got 12."

The ring at the center of the joke is, by any measure, extraordinary. Frangulis proposed on March 3 in a poolside setting arranged with dozens of candles and fresh roses, presenting a 12-carat oval-cut diamond set in a platinum mounting. The stone rides on a curved, micro-pavé band, but the design's most intimate detail is invisible at first glance: emerald accents tucked into the gallery beneath the center stone. Sabalenka's favorite gemstone and her birthstone, woven into the architecture of the piece rather than displayed for show.

The commission belonged to Isabela Grutman, CEO and founder of ISA Grutman Jewelry and a close friend of Sabalenka's. Frangulis spent months working with Grutman on the design before the proposal, a collaboration that produced something specific to its wearer rather than selected from a case. "We spent months working on the design, selecting the stones, and perfecting every detail of the craftsmanship to make it truly special for Aryna," Grutman said after the engagement was announced. On the emerald choice, she added: "What made it even more meaningful was Georgios' idea to incorporate emeralds into the design, as it's her favorite stone, a personal touch that makes the ring uniquely hers."

Sabalenka began wearing the ring publicly almost immediately. At Indian Wells, where she opened her 2026 BNP Paribas Open campaign by beating Himeno Sakatsume 6-4, 6-2, she addressed the choice in a post-match press conference with characteristic directness. "It's very comfortable," she said. "We double-checked if there is a possibility to lose the diamond, and there is none, so I was pretty confident wearing it." She also floated the possibility that the ring's considerable size might work in her favor on court, suggesting it could distract opponents.

Gemologically, a 12-carat oval-cut diamond of any meaningful quality is a substantial acquisition. Experts have estimated the ring's value at close to $1 million, a figure the oval cut's elongated silhouette does nothing to diminish. The shape maximizes face-up size relative to carat weight, meaning a 12-carat oval looks even larger on the hand than a round brilliant of identical weight would. As a competition accessory, it is without precedent in the sport. As a custom piece, it says something more considered: a design conceived over months, with a hidden chromatic detail chosen because of who is wearing it, not because it photographs well.

When the WTA asked Sabalenka what brings sunshine into her life, she answered in sequence: "My ring, my puppy, my family. Priorities, guys." Frangulis may have fallen two carats short of the standing request, but by her own accounting, the result cleared every bar that mattered.
