Claudia Sulewski’s engagement ring from musician Finneas O’Connell stands out for its elongated, antique-inspired cushion-cut appearance and understated band. The couple announced their engagement in September 2025, sharing photographs and videos from their proposal, including close-up views of the ring. They married on August 29, 2026.
Although the ring’s design has attracted considerable attention, its exact diamond specifications and designer have not been officially confirmed in the sources reviewed. Here’s what is known about Claudia Sulewski’s engagement ring, what jewelry experts have estimated, and how to find a similar style.
What Does Claudia Sulewski’s Engagement Ring Look Like?
Claudia Sulewski’s ring features an elongated, cushion-shaped center stone with an antique-inspired appearance. Its substantial-looking center diamond and relatively simple band create a balance between vintage character and contemporary minimalism.
In coverage published by Us Weekly in September 2025, diamond jewelry expert Kristy Cullinane described the ring as an elongated antique cushion-cut diamond in a platinum compass setting. In a compass setting, the prongs are positioned toward the top, bottom, and sides of the stone rather than directly at its corners.
This is an expert’s interpretation of the ring’s appearance, not an official specification supplied by the couple or the jeweler.
The overall look combines several design characteristics:
- Elongated cushion silhouette: A rectangular-looking stone with softened corners gives the ring a distinctive outline.
- Antique-inspired appearance: The cushion shape evokes traditional diamond jewelry while remaining suitable for a modern engagement ring.
- Minimalist band: A relatively understated band keeps attention on the center stone.
- Distinctive prong placement: The reported compass-style setting adds visual interest without requiring an elaborate halo.
The appeal is in the contrast: a visually prominent center stone paired with a comparatively restrained setting.
How Much Does Claudia Sulewski’s Engagement Ring Cost?
The exact price of Claudia Sulewski’s engagement ring has not been publicly confirmed.
In a September 2025 report, Us Weekly cited diamond jewelry expert Kristy Cullinane, who estimated that the ring could retail for approximately $350,000 to $500,000 if its center stone were a natural diamond matching her assessment.
That figure is an expert estimate, not a verified purchase price or appraisal.
The distinction matters because a diamond’s value depends on more than its apparent size. Its grading characteristics, proportions, cut quality, origin, and the specifics of the finished ring can all influence its price.
Other jewelry experts have published different estimates, reinforcing the uncertainty around the ring’s actual specifications and value.
A laboratory-grown diamond could have a substantially different price from a comparable natural diamond. However, there is no verified public confirmation of whether Claudia’s center stone is natural or laboratory-grown.
For anyone shopping for a similar design, it is more useful to compare actual diamond specifications and ring construction than to use a celebrity ring’s estimated value as a shopping benchmark.
How Many Carats Is Claudia Sulewski’s Ring?
Claudia Sulewski’s engagement ring has been estimated at approximately 6 to 7 carats in coverage from Us Weekly and other publications.
However, the couple has not publicly confirmed the center diamond’s carat weight in the sources reviewed.
The estimate should therefore be treated as a jewelry expert’s assessment based on photographs, rather than a verified measurement. Photographs can make a diamond appear larger or smaller depending on camera angle, distance, proportions, and the wearer’s hand.
Carat weight also measures a diamond’s weight, not its exact visible dimensions. Two diamonds with the same carat weight can have noticeably different face-up appearances.
If you are shopping for an elongated cushion diamond, compare its actual length and width alongside its carat weight. These measurements help you understand how much surface area the stone presents from above.
Who Designed Claudia Sulewski’s Engagement Ring?
The ring’s designer or jeweler has not been reliably confirmed in the sources reviewed.
Although several jewelry publications have analyzed its appearance, a description of a ring’s design does not establish who made it.
It is best to avoid attributing the ring to a particular designer without a direct statement from the couple, their representative, or the jeweler responsible for the piece.
Similarly, the exact metal, diamond grading report, color, clarity, and natural or laboratory-grown origin should not be treated as confirmed specifications based on photographs alone.
What can be discussed with greater confidence is the ring’s visible aesthetic: an elongated cushion-shaped center stone paired with a relatively understated band.
What Makes an Antique Cushion-Cut Diamond Special?
Cushion-shaped diamonds combine a soft, rounded outline with a square or rectangular silhouette. Their corners are less angular than those of a traditional princess-cut diamond, which gives them a distinctive appearance.
Antique-inspired cushion designs appeal to shoppers who want something that feels classic without choosing a conventional round brilliant diamond.
Here are several characteristics worth understanding before choosing one.
1. The elongated shape
An elongated cushion has a longer rectangular outline, while a squarer cushion has proportions closer to a square.
Neither is inherently better. The right choice depends on your preferred silhouette, the stone’s proportions, and how it looks when worn.
2. The faceting style
Cushion diamonds can have different facet arrangements. Some produce a lively, brilliant sparkle, while others create broader flashes of light and a more vintage-inspired appearance.
The word “antique” does not automatically mean that a diamond is genuinely old. Modern diamonds can also be cut or selected to create an antique-inspired look.
3. The setting
A simple solitaire setting keeps attention on the center stone. A compass-style setting offers a different visual arrangement of the prongs, while a halo introduces a border of smaller stones.
Each approach changes the ring’s appearance and practical considerations.
4. The importance of individual diamond quality
Two cushion diamonds with similar dimensions may look different because of their proportions, facet arrangement, and overall cut quality.
Before buying, compare the individual stones rather than choosing exclusively by shape or carat weight.

How to Get a Similar Engagement Ring Style
You do not need an enormous diamond or a celebrity-sized budget to capture the same general aesthetic.
The most useful approach is to identify the design elements you like and adapt them to your own budget.
Choose an elongated cushion center stone
Start by deciding whether you prefer a distinctly rectangular cushion or a squarer silhouette. Compare length-to-width proportions and view the diamond from above.
If you like the soft corners and vintage-inspired character of Claudia’s ring, an elongated cushion is a logical starting point.
Keep the band relatively simple
A slender, understated band allows the center stone to remain the focal point.
Consider how the band width, metal, and setting proportions work together. A design should look balanced on the hand and feel comfortable for everyday wear.
Compare natural and laboratory-grown diamonds
Natural and laboratory-grown diamonds are both real diamonds, but they differ in origin and typically in price.
If maximizing the size of the center stone within a particular budget is important, compare both options using the same shape and relevant quality characteristics.
Do not assume that Claudia’s ring uses either type; its diamond origin remains unconfirmed.
Consider the metal and setting carefully
Platinum, white gold, yellow gold, and rose gold can each create a different look.
A compass-style setting may appeal to shoppers who want something more distinctive than a conventional prong arrangement. A traditional solitaire can provide a similar understated effect with a different visual profile.
You can also browse the 1-carat lab-grown diamond engagement ring collection for an accessible starting point when exploring different ring shapes and styles. The collection includes several shapes, but individual product details and availability should be checked before purchasing.
Remember that a celebrity-inspired design is not necessarily an exact replica of the original ring. Focus on the characteristics you like rather than trying to reproduce unverified specifications.
