One of the most recognizable engagement rings in the world, reimagined in blue. The Diana oval aquamarine engagement ring centers a generous two-carat oval aquamarine inside a sparkling halo of simulated diamonds, all set in solid 925 sterling silver with a rhodium finish. It is a royal-inspired silhouette with a serene, ocean-blue heart — timeless, romantic and unmistakably regal.

A royal-inspired halo design
The design takes its cue from the famous sapphire-and-diamond ring that became a symbol of modern romance — an oval center encircled by a bright halo and carried on a pavé-set band. Swapping the deep blue for a lighter, icier aquamarine gives it a fresh, contemporary softness while keeping every bit of that heirloom presence. It is a standout among our aquamarine engagement rings for anyone who wants a ring with a story built in. Explore the wider family of aquamarine rings to see the color in other settings.
The oval aquamarine at its center
An oval cut is prized for looking larger than its carat weight and for elongating the finger, and at roughly two carats this aquamarine has real presence on the hand. Its color is a clear, tranquil blue — the shade that gives the stone its sea-water name. This center is a lab-grown aquamarine, grown to deliver dependable clarity and an even, saturated blue. If you are torn between the classic royal blue and this cooler tone, our comparison of aquamarine versus sapphire engagement rings lays out the differences.
A halo of simulated diamonds
Circling the center and running down the shoulders are simulated diamonds — cubic zirconia selected for their crisp, colorless brilliance. The halo does two things at once: it makes the aquamarine appear larger and it throws off a continuous ring of white sparkle that flatters the blue. It is the detail that makes this design feel red-carpet ready without the red-carpet price. If you are choosing between an aquamarine center and a traditional diamond, our guide on aquamarine versus diamond weighs up the trade-offs. Prefer moissanite or lab-grown diamond accents? Just ask.
Solid sterling silver with a rhodium finish
The ring is crafted in solid 925 sterling silver and plated in rhodium, the same precious metal that finishes fine white gold. That rhodium layer gives the band a bright, mirror-white luster and a protective shield against tarnish and daily scratches, so the silver keeps its just-polished look. It is nickel-free and hypoallergenic, made to be worn every day with confidence.
What aquamarine symbolizes
Aquamarine has long been linked to calm, clarity and faithful love — a fitting emblem for a lasting commitment and the birthstone for March. That blend of meaning and beauty is exactly why it has become such a popular non-traditional engagement stone. For gift ideas that lean into the birthday, see our roundup of March birthstone rings.

Frequently asked questions
What is the center stone?
The center is a lab-grown aquamarine in a clear, tranquil blue, cut as a roughly two-carat oval for maximum presence on the hand.
Is this the Princess Diana style ring?
It is inspired by that iconic oval-and-halo silhouette, reinterpreted with a lighter aquamarine center in place of the original blue sapphire.
How big is the center stone?
The oval aquamarine measures about 9 x 7 mm, approximately two carats, which reads even larger thanks to the surrounding halo.
What are the accent stones?
They are simulated diamonds (cubic zirconia), chosen for their crisp, colorless sparkle. They form the halo and run along the pave band.
What metal is it made from?
Solid 925 sterling silver, finished with rhodium for a bright white luster and added protection against tarnish and scratches.
What does the rhodium finish do?
Rhodium is the same precious metal used to finish fine white gold. It gives the silver a mirror-bright shine and adds a protective layer that keeps the ring looking freshly polished.
Will sterling silver turn my finger green?
No. Genuine 925 sterling silver with a rhodium finish will not turn your skin green. That happens with low-quality or plated base metals, not real sterling silver.
Is aquamarine the March birthstone?
Yes. Aquamarine is the birthstone for March, so this ring doubles as a meaningful birthday gift as well as an engagement or anniversary piece.
Can it be engraved?
Yes. You can add a personal engraving of up to 16 characters at checkout. Engraved pieces are final sale, so please double-check spelling before ordering.
Can I upgrade the accents?
Yes. The halo uses simulated diamonds by default; if you would like more fire, we can craft the design with moissanite or lab-grown diamond accents on request.
Is it suitable as an engagement ring?
Absolutely. The halo silhouette and two-carat center give it genuine engagement-ring presence, and aquamarine makes a distinctive alternative to a traditional diamond.
How do I care for it?
Remove the ring before showering, swimming or applying lotions, store it in the velvet box, and buff with a soft dry cloth. Gentle care keeps the stone and rhodium finish luminous.
Are the stones ethically sourced?
Yes. All of our stones are ethically sourced and conflict-free, so you can wear the ring with complete peace of mind.
Does it arrive gift-ready?
Every order ships in a free luxury velvet gift box and is backed by our lifetime warranty, ready for a proposal or to give as a keepsake.
