Celtic Knot Moss Agate Ring Set in Sterling Silver

An unbroken line, worn on the hand. This Celtic knot moss agate ring set centers a pear-shaped natural moss agate — a green woodland caught in stone — wrapped in flowing Celtic knotwork that has no beginning and no end. Crafted in solid 925 sterling silver with a bright rhodium finish, the engagement ring and matching trinity-knot band nest together as a symbol of eternity, unity and a bond meant to last. Natural moss agate Pear-shaped center Celtic knot detailing Trinity-knot matching band Solid 925 sterling silver Rhodium finish A knotwork set, cast in silver The heart of Celtic design is the endless knot — a single strand that loops back on itself with no start or finish, standing for eternity and interwoven paths. Here those knots wrap gracefully around a pear-shaped moss agate, giving the ring a vintage-inspired, deeply symbolic silhouette. It's a design for couples who want their story written into the metal, an alternative to the conventional solitaire that still feels every bit as romantic.

The engagement ring Holds the pear-shaped natural moss agate in a setting framed by flowing Celtic knots — the statement piece and focal point of the set. The matching band A contour band centered on a Celtic trinity knot, shaped to nest seamlessly against the engagement ring. Lovely stacked or worn alone from our moss agate wedding bands. The natural moss agate Moss agate isn't dyed or treated to look green — the color comes from natural mineral inclusions suspended inside clear chalcedony, forming what look like delicate forest landscapes frozen in stone. Because these patterns form in the earth over millions of years, every moss agate is one of a kind. Yours will share the same lush green character as the stone in our photos, with its own subtle variation in the moss — the mark of a genuinely unique gem, not a flaw. The pear shape, with its softly pointed tip, gives that scenery an elegant, tapering frame.

A crisp diamond accent Simulated diamonds set in precision prongs add a bright flash of white sparkle that lifts the design and makes the green of the moss agate glow even deeper. It's a budget-friendly way to bring classic engagement-ring shimmer to an earthy, nature-inspired set, and it pairs effortlessly with the pear-shaped center.

Solid sterling silver with a rhodium finish The set is crafted in solid 925 sterling silver and finished with a layer of rhodium — the same precious metal used on fine white-gold jewelry. That rhodium finish gives both rings a bright, mirror-white luster and adds a protective shield that helps resist tarnish and everyday scratches, so the fine knotwork stays crisp and freshly polished. It's the detail that lets a sterling silver set wear like something far more expensive.

Frequently asked questions Does this come as a set? Yes — it includes the moss agate engagement ring plus a matching trinity-knot contour band designed to nest seamlessly alongside it. The band can also be worn on its own. What does the Celtic knot symbolize? Celtic knots are drawn as a single, endless line with no beginning or end, symbolizing eternity, unity and interconnected paths — which makes them a deeply meaningful motif for an engagement and wedding set. Is the moss agate natural? Yes. Each moss agate is a genuine natural stone, and its green mossy inclusions form in the earth — never dyed or painted. That's why every stone is unique and yours will look subtly different from the next. What cut is the center stone? A pear shape — a rounded teardrop with a softly pointed tip that gives the mossy landscape an elegant, tapering frame and elongates the finger. What is the accent stone? Simulated diamonds set in precision prongs add a crisp flash of white sparkle that makes the green moss agate glow even deeper. If you'd prefer a lab-grown diamond or moissanite accent, reach out and we'll tailor it for you. 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. 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 fine knotwork crisp and freshly polished. Will my stone look exactly like the photos? It will share the same rich green character, but the exact moss pattern is one of a kind — a hallmark of natural moss agate. No two are ever identical, so yours is truly one of a kind. Do the two rings sit flush together? Yes. The matching band is contoured to nest against the engagement ring so the two sit flush as a seamless set, continuing the knotwork theme around the finger. Can it be engraved? Yes. You can add a personal engraving of up to 16 characters at checkout — a date, initials or a short message. Engraved pieces are final sale, so please double-check spelling. Is moss agate durable enough for daily wear? Moss agate sits around 6.5–7 on the Mohs scale, making it well suited to everyday wear with normal care. Avoid hard knocks, and remove the rings for rough activities to keep the stone pristine. Are the stones ethically sourced? Yes. All of our stones are ethically sourced and conflict-free, so you can wear your set with complete peace of mind. Can I see other moss agate designs? Absolutely.
