Aryna Sabalenka reveals 12-carat custom engagement ring with emeralds

Aryna Sabalenka put her 12-carat engagement ring back in the spotlight in a July 10 Instagram video, and Georgios Frangulis said finding a stone that large took serious effort. Sabalenka described the piece as having two layers of emeralds and a very beautiful cut, a reminder that oversized bridal jewelry depends on more than carat weight alone.

The ring first surfaced when Frangulis proposed on March 3, 2026, in front of a pool covered in white rose petals and an elaborate floral display. Sabalenka announced the engagement on Instagram with the caption, “You & me, forever 3.3.26 .” WTA shared the proposal video and a glimpse of the ring, turning the moment into an early close-up of one of the more discussed pieces in tennis-adjacent luxury jewelry this year.

The ring was described as a custom 12-carat oval diamond set in platinum and accented with emeralds. Emeralds were an apt choice for Sabalenka, since they are both her favorite stone and her birthstone, and they softened the scale of the center diamond with a green frame that felt personal rather than ornamental. The piece was custom-made over months with jeweler Isabela Grutman through Isa Grutman Jewelry, which helps explain why the final result reads as considered rather than merely large.

Frangulis said 15 carats would have felt too flashy, even too tacky, a detail that exposes the tightrope oversized engagement rings have to walk. At that scale, the challenge is not only sourcing a stone with the right proportions and cut, but also keeping the design wearable enough for daily life. Platinum gives the setting a cleaner, sturdier backbone, while the emerald accents add visual weight without pushing the ring into excess.

Sabalenka and Frangulis were publicly linked by early 2024, and the ring kept drawing attention when Novak Djokovic congratulated her and took a closer look at Indian Wells Tennis Garden in Indian Wells, California. WTA later folded the engagement and Sabalenka’s new dog, Ash, into her strong 2026 run before her Indian Wells title. The ring’s appeal lies in that balance: a headline-grabbing 12 carats, but also the sourcing, the setting, and the discipline needed to make something that large look intentional.
