A Deep Dive Into Aryna Sabalenka’s Engagement Style: Oval-Cut Diamond Rings

Belarusian tennis star Aryna Sabalenka recently announced her engagement to longtime boyfriend Georgios Frangulis, and as with many celebrity engagements, all eyes turned toward her stunning diamond ring. Sabalenka, however, is going a step further than most athletes and has been wearing her new jewelry on the court. She raised her hand to the crowd and sent radiant refracting light in every direction during a BNP Paribas Open match at Indian Wells.

Sabalenka wears her large, oval-cut ring well. She has been showing off the beautiful piece both on and off the tennis court, even finding humor in the striking glamour. Of her ring, she has said: “It feels shiny. I hope that my opponent will get distracted by this diamond and it is going to benefit me.” If you have seen photos of her ring, you can certainly understand how that exact scenario might occur.

Whenever a celebrity or athlete gets engaged, trends often swing toward their diamond of choice. After Taylor Swift’s 2025 engagement, old mine cut diamonds were especially desirable. Selena Gomez sparked newfound interest in marquise-cut stones. And now, we expect oval-cut diamonds to top the charts once again. Join us as we spotlight some of our favorite oval-cut diamond rings from Diamonds by Avi & Co.

Aryna Sabalenka is not just any women’s tennis player. She holds 23 WTA singles titles as well as four Grand Slam tournament titles: 2023 and 2024 Australian Open wins and 2024 and 2025 U.S. Open wins. She was also a finalist at Roland Garros, the French Open, in 2025. Wimbledon, where there are grass courts, plays less to her strengths, though she has often been a semifinalist in England. She took home the trophy at Indian Wells this past weekend, turning a series of losses there into an impressive triumph over Elena Rybakina.

Sabalenka’s fiancee, Georgios Frangulis, is a Brazilian entrepreneur and founder of Oakberry, a health and wellness brand specializing in products derived from the acai berry. Frangulis may not be a household name in the way that Sabalenka is, but he certainly has had his fair share of fame, gracing the cover of Forbes Brazil in 2023. He is also a devoted supporter of Sabalenka’s tennis career, and the two have often been spotted together during WTA circuit events.

In early March 2026, Frangulis popped the question during a romantic outdoor dinner, during which the two were seated poolside and surrounded by candles. Both Frangulis and Sabalenka have since expressed enthusiasm about their upcoming nuptials. But the true highlight of the proposal was the stunning oval-cut diamond ring that Sabalenka is now wearing on her left hand. In honor of this exciting new chapter for the world’s top female tennis player, we have curated a selection of our favorite oval-cut diamond rings.

Oval-cut diamonds have long been a strong choice for engagement rings, and their popularity has spiked in recent years. They offer feminine curves and a relatively traditional shape while providing an elongated silhouette that is slimming on the finger and tends to look larger than a round diamond of the same carat weight. Oval-cut diamonds are also versatile, lending themselves to many different setting styles and metals. Here are a few of our favorite oval-cut diamond rings to consider if you are planning a proposal in the upcoming months.

This luminous platinum ring from Diamonds by Avi & Co. shows off both oval and pear-cut diamonds. The center stone is an oval-cut masterpiece, a brilliant 10.02-carat diamond that is sure to turn heads every single day. It is flanked by two pear-cut diamonds, totaling 1.2 carats. These side stones add an additional touch of sparkle and elevate the ring to new levels of sophistication. All three diamonds are artfully sent in the hypoallergenic and highly durable platinum band, a perfect match for those who gravitate toward white gold jewelry. This ring walks the line between timeless and modern styles. It is sure to become a family heirloom that represents the beginning of a wonderful life together.

A 10-carat engagement ring is guaranteed to make an impact. This stunning central diamond is set on a platinum diamond pave band with an additional 1.25 carats of stones on the setting and band combined. The largesse of the diamond itself is sure to turn heads: This is a showstopping ring meant for a woman who commands the room. It is an iconic piece of jewelry, and perhaps the ring most similar to Aryna Sabalenka’s in our current inventory. If you are not sure exactly what your future spouse is looking for, our experienced team at Diamonds by Avi & Co. is happy to work with you to choose a piece that will capture her heart when you are down on one knee.

Contrary to popular knowledge, diamonds come in a wide variety of colors. White diamonds (which really are more transparent than white) are the most common option in jewelry, but these durable and exquisite stones are also available in many other interesting hues. Colors besides white are known as “fancy diamonds,” and they offer a rare and personalized touch when you are shopping for an engagement ring. Take this pink diamond ring, for example. The central diamond measures an impressive 20.53 carat in weight and is surrounded by a halo of smaller stones as well as more diamonds in the band, adding another 1.75 carats of white diamonds. The band is crafted from luminous and prestigious platinum, while 18K rose gold is used to secure the stone, offering a warm tone that perfectly complements the central stone’s cherry blossom tones. This pink, oval-cut diamond is perfect for someone who loves a traditional shape but wants to depart from convention with an unusual hue that evokes individuality and glamour.

Oval cut diamonds are not reserved exclusively for traditional engagement ring settings. While they certainly work well in that format, you will also see prestigious jewelers using this feminine and graceful shape in eternity bands, bracelets, earrings, and more. This fancy yellow diamond eternity band is the perfect complement to an existing engagement ring and would also make an excellent anniversary gift, milestone birthday present, graduation gift, push present, and more. It is crafted from 18K yellow gold and is set with twelve meticulously set oval-cut diamonds, totaling 18.47 carats in all. Its graceful elegance and vintage flair epitomize the beauty that yellow diamonds have to offer and make it an ideal option for someone who loves heirloom jewelry that transcends the typical offerings you will see from mainstream vendors. Here at Avi & Co., we know that individuality and creativity goes hand in hand with building your reputation as a sophisticated and stylish modern woman.

Seeing oval-cut diamonds outside of solitaire settings is always a thrill for us. We appreciate the avant garde artistry and unique appearance of this exquisite toi et moi ring, which translates to from French to you and me. The two oval-cut stones on this beautiful platinum setting evoke the two souls uniting in a lifelong union upon marriage. Toi et moi rings can be engagement rings, but they can also mark milestone occasions like anniversaries, birthdays, graduations, beginning motherhood, or other major life accomplishments. This platinum toi et moi ring showcases a bold yet harmonious pairing of two center stones: a 3.60-carat fancy blue oval cut diamond and a 3.49-carat white oval cut diamond. Both stones are surrounded by a halo of smaller white diamonds to add to the prestige and sparkle of the ring. The dramatic band is also set with stones for maximum impact in this evocative and memorable design. We love this modern interpretation of the duality of love, yin and yang, and two halves creating a whole.
