The Simone Biles engagement ring has attracted attention because of its large oval diamond, diamond-covered band, and personal design details selected by Jonathan Owens. The couple became engaged on Valentine’s Day in 2022, and the ring was produced by Houston jeweler ZoFrost. Published reports generally describe it as a three-carat oval-cut diamond, although early visual estimates placed the center stone much higher.
That difference has led to frequent questions about how many carats the ring contains, how large it appears on her hand, and how much Jonathan Owens may have paid. The most responsible answer is that the exact purchase price has never been publicly confirmed. The strongest later reports identify the center stone as three carats, while an early industry estimate suggested seven to nine carats and a value near $325,000.
What Does the Simone Biles Engagement Ring Look Like?
The ring centres on an elongated oval-cut diamond rings positioned vertically on the finger. The diamond is held by four visible prongs, which secure the stone without covering much of its face. A narrow white-metal band is set with small diamonds. This pavé treatment creates a continuous line of light along the finger while keeping the centre diamond as the main feature. Photographs also show that the band is proportionally thin compared with the centre stone, making the oval appear even larger.
Houston jeweler ZoFrost produced the ring after working directly with Jonathan Owens. ZoFrost later explained that Owens took part in selecting the centre diamond and asked for an additional halo around the oval.
The halo is not always easy to see in photographs taken from above. It appears to sit around or beneath the centre stone, depending on the viewing angle. This adds more small diamonds close to the oval without creating the wide border associated with some traditional halo rings. Similar attention to unique diamond arrangements can also be seen in designs like toi et moi rings, where multiple stones are positioned together to create a distinctive and meaningful jewelry style.
Simone Biles Engagement Ring Design

One of the most recognizable features of the Simone Biles engagement ring is its oval-cut center diamond. Oval diamonds are appreciated because they create the appearance of greater length across the finger while offering impressive surface area.
The hidden halo beneath the center stone is another important feature. Instead of placing smaller diamonds around the top edge, this style positions them beneath the center diamond where they become visible from side angles. This adds extra brilliance without changing the clean look of the ring when viewed from above.
The ring also appears to feature a slim band that keeps attention focused on the center stone. A thinner band often makes a larger diamond appear even more prominent while maintaining comfortable everyday wear.

What Is Simone Biles Engagement Ring Cost?
One early published estimate valued the ring at approximately $325,000. That figure was connected to the belief that the centre diamond could weigh seven to nine carats. Once the centre is reported as three carats, the $325,000 estimate becomes harder to evaluate without knowing the remaining quality details. A three-carat mined diamond can vary greatly in price depending on its color, clarity, cut quality, fluorescence, proportions, certification, and whether the stone carries a premium for its source or custom selection.
The custom work also affects the final amount. The price may include:
A hand-selected centre diamond, custom design work, a halo, pavé diamonds, white gold, setting labour, consultation time, and any private-client services provided by the jeweler all contribute to the final price. For buyers comparing options such as lab grown diamond rings under $4000, understanding these factors can help them evaluate diamond quality, design details, and overall value. GIA notes that diamond value is strongly influenced by the 4Cs: color, clarity, cut, and carat weight. Two diamonds that look similar in a photograph can have very different prices because of differences documented in their reports.
Why the Simone Biles Engagement Ring Became So Popular
Celebrity engagement rings often influence jewelry trends, but the ring chosen for Simone Biles stands out because of its balanced proportions and refined craftsmanship. Rather than relying on an oversized setting or complex design, the ring highlights an oval center diamond supported by carefully designed details.
The proposal photos quickly spread across social media and news outlets, leading many people to search for information about the ring's size and estimated price. Interest continued because the ring combines several design elements that remain popular among couples choosing engagement rings today.
Some of the reasons behind its popularity include:
- Large oval center diamond
- Hidden halo beneath the center stone
- Thin polished band
- Bright white precious metal
- Four-prong setting that emphasizes the diamond
These characteristics work together to create a ring that looks balanced from every angle.
How to Create a Simone Biles-Inspired Ring
A celebrity-inspired ring should focus on the main design language rather than copying the piece line for line. Start with an oval centre diamond. Decide whether you prefer a balanced oval, a longer outline, or a fuller shape. Compare several stones on video because two ovals with the same grades can display different light patterns and bow ties.
Next, choose a four-prong setting that protects the centre without hiding its outline. Ask how the basket supports the diamond and whether the prongs can be serviced in the future. For the band, a narrow pavé shank will create a look closer to the Simone Biles engaged ring. A plain band will be easier to maintain, while a channel-set or slightly wider pavé band can offer more protection for the smaller stones.
A halo can be placed in different positions. A visible halo creates more width from above. A hidden halo is mainly seen from the side. A compact halo placed close to the oval can sit between these two approaches. White gold gives a similar overall colour direction to the reported original ring. Platinum is another option for buyers who prefer a naturally white metal and are comfortable with its added weight and price.

Find the Right Diamond Carat Size for Your Perfect Ring
Selecting the ideal diamond carat size depends on your style preferences, budget, and the overall design of your engagement ring. A larger carat weight can create a bold appearance, but diamond shape, cut quality, and setting style also influence how impressive the stone looks. At Antiquecut, you can explore carefully crafted lab-grown diamond engagement rings in different carat sizes to find a design that matches your vision and lifestyle.

Simone Biles’ personal finger size is not publicly confirmed, so shoppers should not use her hand photographs to estimate their own size. Professional measurement is the safest option. Finger size may change with temperature, time of day, pregnancy, weight changes, and the width of the band.
A narrow pavé band can fit differently from a wide band. Some settings can be resized without difficulty, while full-eternity or heavily detailed bands may have stricter limits. Before ordering, confirm whether the jeweler uses US sizing, whether quarter sizes are available, and how many sizes the ring can be adjusted after production. Also ask how resizing could affect the pavé section.
How to Choose the Perfect Diamond Carat Size
Choosing the perfect diamond carat size is about finding the right balance between appearance, budget, and personal style. While a higher carat weight often creates a larger-looking diamond, factors such as cut quality, shape, and setting also play an important role in how impressive the diamond appears. Understanding these elements helps you select a ring that matches your preferences without focusing only on size.
This article explains how diamond carat size affects appearance, compares popular carat ranges, and highlights the factors to consider before making your purchase. Whether you're shopping for a classic solitaire or a custom engagement ring, you'll learn how to choose a diamond that suits your style and budget.

Conslusion
The Simone Biles engagement ring features a large oval centre, four-prong setting, custom halo, pavé band, and white-metal finish. The strongest reports identify the diamond as approximately three carats and confirm that Houston jeweler ZoFrost worked with Jonathan Owens on the design.
Although one early estimate valued the piece near $325,000 and placed the diamond between seven and nine carats, neither figure was officially verified. The final price, exact dimensions, quality grades, and Biles’ personal ring size remain private.
For buyers inspired by the design, the most useful features to consider are the oval diamond’s face-up proportions, secure four-prong construction, halo position, pavé quality, and band width.
