Knotwork and knots that never end
The story here is in the band. Traditional Celtic knotwork, endless interlacing with no beginning and no end, wraps around the aquamarine as an ancient symbol of eternal love and connection. It gives the set a woven, sculptural texture that feels worlds away from a plain solitaire, and pairs the fantasy-cut center with real meaning. It sits beautifully among our other aquamarine engagement rings for anyone after an alternative with a story to tell.
The engagement ring
Holds the fireworks fantasy-cut aquamarine within the Celtic knotwork setting, the radiant focal point of the set.
The matching band
A coordinating knotwork band that nests alongside the engagement ring to complete the woven silhouette. Also lovely stacked from our aquamarine couples rings.
The fireworks fantasy-cut aquamarine
The center is a simulated aquamarine, a 6 x 8 mm oval faceted in the elaborate fireworks fantasy cut, where extra bursts of faceting scatter the light for a lively, radiant flash. It glows the icy sky blue aquamarine is famous for, chosen for vivid, consistent color. Love the shape? Explore more silhouettes in our aquamarine rings edit, and if a bold, faceted look appeals, our feature on the kite cut aquamarine ring shows another striking option.
Simulated diamond accents
Simulated diamonds (cubic zirconia) trace the setting, adding crisp, colorless fire that makes the blue center glow deeper. We keep every material clearly labeled, so you always know exactly what you are wearing. Prefer moissanite or lab-grown diamond accents for extra brilliance? Most of our designs can be upgraded on request.
Solid sterling silver with a rhodium finish
The set is crafted in solid 925 sterling silver and finished with rhodium, the same bright metal used on fine white gold. That rhodium finish gives both rings a mirror-white luster and adds a protective shield against tarnish and everyday scratches, so the silver keeps its freshly polished shine. It is also hypoallergenic and nickel-free, kind to sensitive skin.
What aquamarine and Celtic knots symbolize
Aquamarine, the March birthstone, has long stood for clarity, peace and loyalty, its sea-blue color a token of calm and steady love. Bound with the unbroken Celtic knot, a symbol of infinity and eternal connection, the set becomes a quiet promise of a bond without end.

Sizing & care
Made to order in your size, hypoallergenic and nickel-free. If you are between sizes or unsure, we are glad to help, and if the fit is not quite right, resizing is available and starts from a modest fee.

Frequently asked questions
Does this come as a set?
Yes. It is a two-piece set that includes the aquamarine engagement ring plus a matching Celtic knotwork band designed to nest alongside it.
What kind of aquamarine is the center stone?
It is a simulated aquamarine, chosen for its vivid, consistent icy-blue sparkle and glassy clarity. It gives you the exact sea-blue tone aquamarine is loved for.
What is a fireworks or fantasy cut?
It is an elaborate faceting style with extra bursts of sparkle across the stone, giving the aquamarine a lively, radiant look that catches the light from every angle.
What makes it Celtic?
The band is woven with traditional Celtic knotwork, endless interlacing that symbolizes infinity and eternal love, a meaningful detail with roots in old legend.
What are the accent stones?
They are simulated diamonds (cubic zirconia), chosen for crisp, colorless fire that makes the blue center glow deeper without competing with it.
Can I upgrade the accents?
Yes. If you would prefer moissanite or lab-grown diamond accents for extra brilliance, reach out before ordering and we can craft the design that way. Solid gold upgrades are also available.
What metal is it made from?
Solid 925 sterling silver with a rhodium finish for a bright white luster and added protection. It is hypoallergenic and nickel-free.
What does the rhodium finish do?
Rhodium is the same precious metal used to plate fine white gold. It gives the silver a mirror-bright shine and adds a protective layer that keeps both rings 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. Green marks come from low-quality or fake metals, never from real sterling silver.
Is aquamarine a birthstone?
Yes. Aquamarine is the birthstone for March, which makes this a meaningful March birthday or anniversary gift as well as an engagement or promise set.
Is this good for an alternative engagement?
Absolutely. The fantasy-cut aquamarine and Celtic band make it a beautiful, story-rich alternative to a conventional solitaire, and it works just as well as a promise ring.
Are the stones ethically sourced?
Yes. All of our stones are ethically sourced and conflict-free, so you can wear the set with complete peace of mind.
Does it arrive gift-ready?
Every order ships in a free luxury velvet gift box with free U.S. shipping and a lifetime warranty, ready for a proposal or to give as a keepsake.
