Two matching pieces built around the same stone: a Celtic knot engagement ring and chevron band in sterling silver for her, and an 8mm brushed tungsten band with an off-set moss agate inlay for him. Three rings in total — her side is a two-ring stack. Choose both sizes at checkout, and add engraving to either ring or both.

What Is in the Set

One Stone, Two Ways

What ties the set together is not a shape or a metal — it is the moss agate itself, used two completely different ways. Hers is a single faceted pear, cut and polished so you read the green inclusions as a landscape inside a clear stone. His is the same material crushed into fragments and set flush in a channel, so it reads as texture rather than as a gem.

That is deliberate. Matching sets that copy one design onto a wider band usually leave one partner wearing something that does not suit them. This pair shares a material and a color and nothing else, which is why the rings look related without looking identical.

Celtic Knotwork

The trinity knot — the triquetra — is a single unbroken line folded into three loops, and it has been used for over a thousand years to stand for continuity: no beginning, no end, no seam. On a wedding set that reading needs no explanation. Hers carries four of them, two flanking the centre stone and one crowning each band.

Natural Moss Agate

Moss agate is not banded agate — it is translucent chalcedony with green mineral inclusions that spread like lichen or bare winter branches. It has been called the gardener's stone for centuries, and in crystal traditions it is tied to growth, grounding and new beginnings, which is a fair thing to put on a marriage. Our guide to moss agate meaning covers the symbolism, and is moss agate durable gives the honest daily-wear answer.

Because the stone is natural, both rings vary. Her centre stone's pattern of green is unique to it, and the crushed fragments in his band settle differently in every ring. The metal, the cut and the sizes are identical on every set; what is inside the agate is not.

Two Metals, One Reason

Her rings are solid 925 sterling silver with a rhodium finish. His is tungsten carbide in its natural silver-gray. Both read as white metal from any normal distance, so the set looks like a set — but each ring is made from the material that suits how it will be worn. Sterling takes fine detail and holds a set stone; tungsten survives a hand that works.

The practical consequence is that they age differently and are cared for differently. His cannot be resized at all.

Sizing and Engraving

Choose His Ring Size and Her Ring Size separately above — both are required. His runs 7 to 13, hers 4 to 11, all including half sizes.

Tick Add Engraving to open the engraving fields. His band takes up to 25 characters, hers up to 16 — the difference is simply how much inner surface each ring has. You can engrave one ring, the other, or both. Please check the spelling before you order.

His band cannot be resized. Tungsten is too hard to stretch or cut and rejoin, so his size has to be right at the point of ordering. Comfort fit also runs slightly large — many people take a quarter to a half size smaller than in a standard-fit ring.

The rings are also sold individually: the Celtic knot moss agate ring set and the off-set moss agate men's band. See more in our couples rings and moss agate jewelry collections.

Care

The two rings want different things. Hers: warm water, mild soap and a soft brush, paying attention to the knotwork where lotion collects; avoid abrasive polishes and chlorine, which wear the rhodium. His: a soft damp cloth only — no polishing cloths or compounds, which will burnish the brushed finish into a patchy shine. Neither ring should go near an ultrasonic cleaner, and both should come off for the gym, heavy lifting and swimming. Our guides to cleaning sterling silver and cleaning moss agate safely cover the detail.
