Love without end, spelled in silver knots. This Celtic London blue topaz ring set centers a natural oval-cut topaz — deep, teal-blue and full of quiet depth — on a band woven with Celtic knotwork, then pairs it with a matching band so the two rings nest as one. Crafted in solid 925 sterling silver with a rhodium finish, it is a meaningful December birthstone engagement or promise set for her.

A Celtic-inspired ring set
The endless Celtic knot has no beginning and no end — the oldest symbol of eternal love and unity — and it is woven through the band of this set. A three-stone-style silhouette holds the topaz between simulated diamond side stones, while a matching Celtic band completes the pairing so the rings sit flush together. It is a romantic, affordable way to say forever, at home among our topaz couples rings and the broader topaz engagement rings collection.
The engagement ring
Holds the natural London blue topaz between simulated diamond side stones on a Celtic knotwork band — the statement piece and focal point of the set.
The matching band
A coordinating Celtic band that nests flush against the engagement ring, completing the woven silhouette. Beautiful stacked or worn alone as a promise ring.
The natural London blue topaz
The center is a natural London blue topaz, an oval measuring about 6.0 x 8.0 mm in that rich, deep teal-blue that gives London blue its name — the most saturated shade in the blue topaz family, and a striking contrast to warmer stones if you are weighing how topaz and citrine compare. As the December birthstone, it is celebrated for its calming energy; our complete December birthstone guide tells the fuller story. You can find more designs in the dedicated London blue topaz rings collection.
Simulated diamond side stones
Framing the topaz, bright simulated diamonds (cubic zirconia) add a crisp flash of white that makes the blue read even deeper. We keep every material clearly labeled so you know exactly what you are wearing — a natural topaz center with brilliant, budget-friendly CZ accents. Prefer lab-grown diamond or moissanite side stones, or a solid-gold upgrade? Message us and we will tailor it.
Solid sterling silver with a rhodium finish
Both rings are crafted in solid 925 sterling silver and finished with rhodium, the same precious metal used on fine white-gold jewelry. That rhodium layer gives the silver a bright, mirror-white luster and adds a protective shield that helps resist tarnish and everyday scratches. The set is hypoallergenic and nickel-free, made to be worn together every day.
What the design symbolizes
Between the endless Celtic knot — a promise of unbroken love — and blue topaz, a stone whose meaning and symbolism center on calm, clarity and honest connection, this set carries layers of meaning. It makes a heartfelt alternative engagement ring, promise ring, anniversary gift or December birthday gift — and if you are unsure which stone is yours, our guide to what is my birthstone makes it simple to check.

Frequently asked questions
Is the topaz natural?
Yes. The center is a natural London blue topaz, the deepest and most saturated shade in the blue topaz family. The side stones are simulated diamonds (cubic zirconia).
Does this come as a set?
Yes. It includes the engagement ring plus a matching Celtic band designed to nest flush against it. The band can also be worn on its own as a promise or stacking ring.
What makes it Celtic?
The band features Celtic knotwork — the endless knot, an ancient symbol of eternal love and unity with no beginning and no end.
What cut is the center stone?
An oval cut, about 6.0 x 8.0 mm, which lengthens the finger and shows off the depth of the London blue color.
What are the side stones?
Bright simulated diamonds (cubic zirconia) that frame the topaz and add crisp white sparkle. Lab-grown diamond or moissanite upgrades are available on request.
What metal is it made from?
Solid 925 sterling silver, finished with rhodium for a bright white luster and extra protection against tarnish and scratches. Hypoallergenic and nickel-free.
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 both rings looking freshly polished.
Is blue topaz a birthstone?
Yes. Blue topaz is a December birthstone, which makes this set a meaningful December birthday, engagement or anniversary gift.
Is topaz durable enough for daily wear?
Topaz rates 8 on the Mohs scale, suitable for everyday wear with reasonable care. Remove the rings for rough activities and avoid hard knocks to keep them pristine.
Can the rings be worn separately?
Yes. The engagement ring stands beautifully on its own, and the Celtic band works as a promise or stacking ring when worn alone.
Can I have the set resized?
Each set is made to order in your chosen size. If you are unsure or between sizes, contact us for guidance. Resizing is available and starts from a modest fee.
Are the stones ethically sourced?
