The Princess Beatrice engagement ring features a 2.5-carat round brilliant center diamond flanked by tapered baguette diamonds adding roughly 0.75 carats combined, set in platinum. Edoardo Mapelli Mozzi proposed to Princess Beatrice in Italy in September 2019, and the ring is estimated to be worth around $165,000. This article covers the ring's design story, its materials, how it compares to other well known royal rings, and what US shoppers should know if they want a similar look for their own engagement ring.
Who Designed the Princess Beatrice Engagement Ring
British jeweler Shaun Leane created the ring in close collaboration with Mapelli Mozzi. Leane is known for his work with Alexander McQueen rather than royal commissions, which made him an unexpected but fitting choice for a couple that wanted something personal rather than conventional. The two worked together for about four months before the proposal, discussing stone shape, metal, and overall style before any final design was set.
Leane described the ring as a fusion of two distinct design periods. At first glance, it appears to be a classic solitaire, but closer inspection reveals details inspired by both eras. Chiseled prong work frames the center stone, while pavé diamonds extend along the shoulders of the band. These design elements give the pavé diamond engagement ring a traditional profile with added period-inspired character.
Ring Specifications
The ring features a 2.5-carat round brilliant cut diamond as the center stone, paired with two tapered baguette diamonds that add around 0.75 carats in total. Set in platinum, the band is finished with pavé diamonds along the shoulders, while six pointed prongs hold the center stone securely in place. This design is a strong reference for anyone considering a round lab grown diamond engagement ring with side stones and a detailed platinum setting.
Additional details reported by the designer and jewelry press include:
- Round brilliant cut center diamond, approximately 2.5 carats
-
Tapered baguette side stone, approximately 0.75 carats combined
- Platinum band with pave diamond detailing
- Six-prong setting with pointed, talon-style prongs
- Diamonds described as high color and clarity, ethically sourced
Some outlets have estimated the center stone closer to 3.5 carats, since the ring's exact grading report has not been made public. The 2.5-carat figure comes directly from Leane's own statement at the time of the announcement, which makes it the more reliable number for buyers researching the ring.
How Much Is the Ring Worth
Leane has never confirmed the ring’s official price. Independent jewelry appraisers have estimated its value at around $165,000 based on the center diamond’s carat weight, cut, platinum setting, and the cost of custom design work from a well-known jeweler. This figure remains an estimate because no formal appraisal or certification value has been released publicly.
For US buyers comparing the cost of a similar design, the main price factors include the center diamond’s carat weight, color, clarity, cut grade, and origin. A natural round brilliant diamond close to 2.5 carats can vary significantly in price depending on these specifications. A lab-grown diamond with a similar size and grade generally costs much less. Buyers working with a smaller budget can also explore lab-grown diamond rings under $1000, although these options will usually feature a lower carat weight, simpler setting, or fewer side stones.
Comparing the Ring to Other Royal Engagement Rings
Princess Beatrice's ring is often compared to her grandmother Queen Elizabeth II's engagement ring, which also features a diamond solitaire in a platinum setting with smaller diamonds along the band. The resemblance appears to be intentional, since Leane has said the design paid tribute to family style. The table below outlines the main differences between the two rings and a few other well known engagement rings for comparison.
| Ring | Center Stone | Estimated Carat | Metal | Setting Style |
|---|---|---|---|---|
| Princess Beatrice | Round Brilliant Diamond | 2.5 CT | Platinum | Six-Prong Setting with Pavé Band |
| Queen Elizabeth II | Old-Mine Cut Diamond | Undisclosed | Platinum | Five Pavé Diamonds on Each Side |
| Meghan Markle | Diamond Trilogy | 3 CT Total | Yellow Gold | Two Side Stones from Princess Diana’s Collection |
| Kate Middleton | Ceylon Sapphire | 12 CT | White Gold | Diamond Halo Setting |
Buying Considerations for a Similar Ring
US shoppers interested in a ring inspired by this style should think through a few practical factors before ordering.
Stone choice and certification. Ask for a grading report from GIA or IGI for any diamond over half a carat. These reports confirm carat weight, color, clarity, and cut, and they also state whether the diamond is natural or lab grown, which the Federal Trade Commission requires jewelers to disclose clearly.
Gold or platinum. Platinum is more resistant to wear and does not require replating over time, though it costs more than gold. If a lower budget is a priority, 14K white gold offers a similar look at a lower price point, while 18K gold is softer but has a richer color.
Setting durability. A six-prong setting like the one used here holds the center stone securely, which matters for daily wear. Pave detailing along the band adds visual interest but requires more careful cleaning, since dirt collects more easily around small stones.
Sizing and resizing. US ring sizes typically range from size 4 to size 10 for adults. Most jewelers offer one free resizing within a set return window, though rings with pave stones set all the way around the band can be harder to resize without disturbing the stones.
Common Buyer Mistakes
Buyers researching a ring like this sometimes focus only on carat weight and skip cut quality, which has the biggest effect on how bright a diamond looks. Others assume a bespoke design will cost less than it does, without accounting for the design consultation time that goes into a one-of-a-kind piece. It also helps to confirm return policies and production timelines in writing before placing a custom order, since custom pieces are often excluded from standard return windows.
Care and Maintenance
Platinum settings hold up well over time but can develop a soft patina with regular wear, which some owners prefer and others choose to have polished back to a bright finish. Pave diamonds should be checked once or twice a year by a jeweler to confirm none of the small prongs have loosened. Cleaning at home with mild soap and warm water, followed by a soft brush, is usually enough between professional cleanings.
Conclusion
The Princess Beatrice engagement ring combines a 2.5-carat round brilliant diamond with tapered baguette side stones in a platinum setting, designed by Shaun Leane with input from Mapelli Mozzi over several months. Its blend of Art Deco and Victorian details, along with its connection to Queen Elizabeth II's own ring, has made it one of the more discussed royal rings in recent years.
