Aryna Sabalenka unveiled the centerpiece of her March 3 engagement on July 10, posting an Instagram video that details the 12‑carat diamond ring her fiancé Georgios Frangulis secured. The tennis star, 27, described the stone’s cut and emerald accents, while Frangulis explained the hunt for a “massive” yet tasteful gem.

How did the ring come together?

In the clip, Sabalenka holds the oval‑cut diamond up to the camera, noting its two layers of emeralds and “very beautiful cut.” She says she originally wanted a 15‑carat stone because “I’m a big girl and I have quite big fingers.” Frangulis counters that an 11‑12 carat piece was already at the upper limit, calling 15 carats “too tacky” and “too expensive.”

Who crafted the jewelry?

According to the Daily Mail, the ring was designed by Isabela Grutman, founder of an eponymous jewelry line. Frangulis, the founder of Oakberry, collaborated with Grutman for months to create a one‑of‑a‑kind piece that mirrors Sabalenka’s on‑court reputation. The final design features a 12‑plus carat oval diamond set in platinum, surrounded by emeralds—her favorite gemstone.

Why the engagement matters now?

The couple announced their engagement a day after the proposal, sharing photos of the ring on Instagram. The timing follows a difficult period for Sabalenka; she lost ex‑boyfriend Konstantin Koltsov to suicide in March 2024. In an August 2024 interview, she credited Frangulis with providing steady support during her grief. The public reveal of the ring adds a celebratory note to her personal narrative as she prepares for the upcoming grass‑court season.

What’s next for the pair?

Frangulis hinted that the ring is “the most special part of the proposal, aside from the proposal itself,” suggesting future plans may soon be announced. Sabalenka’s fans will likely watch for wedding details as the tennis star continues her 2026 campaign, aiming to improve her ranking ahead of Wimbledon.
