Six claws on the centre. Three separate boxes down each shoulder, each holding one stone.

A round brilliant moissanite sits high in a six-claw crown. Either side, the band doesn't run smooth into the head — it steps up into three individual raised boxes, square-walled and flat-topped, each with a small moissanite set down inside it.

Six boxes, six stones, counted out along the band like beads on a rail.

Boxes, not a channel

The usual way to set stones down a shoulder is a channel: one long groove, stones dropped in side by side, metal walls either end. It reads as a continuous line of sparkle.

Here each stone gets its own box, and the boxes are separated by gaps of plain polished metal.

Separation is the whole design. You can count the stones. Each one has its own square frame, its own four walls, its own shadow — so the shoulder reads as a sequence of objects rather than a stripe of light. It is architectural where a channel is decorative.

The gaps also mean the shoulder stones never compete with the centre. In a channel, the line of light runs straight into the head and the eye follows it past the main stone. Broken into six, the shoulders lead up to the centre and stop.

The stones sit low in their boxes

Look into any box and the stone is set down below the rim, not flush with it.

This is deliberate and it is the opposite of how most side stones are treated. Recessed, the stone is protected on all four sides by a wall of metal — a shoulder stone set proud is the first thing to catch on a door handle, and the first to come loose.

The recess also does something to the light. Each stone sits at the bottom of a small bright box, and the polished inner walls bounce light back down onto it. The stones look deeper than they are, and they flash when the ring turns rather than glowing constantly.

Six claws, and why they're that tall

The centre moissanite is held in six claws, set high, with clear air underneath it.

Moissanite throws more fire than diamond — it splits light into colour more strongly. That fire comes from light entering the stone from every direction, including below. Drop a moissanite into a low, closed setting and you get a bright white stone. Lift it, open the underside, and you get the colour it's capable of.

Six claws rather than four for one reason: with six, no single claw is critical. Four claws and a damaged one is a problem; six and it's an appointment.

The band

Flat-sided, plain from the last box all the way round the back. It is a square-shouldered band, not a round one, which is what lets the boxes sit on it without looking bolted on. The flat outer face runs into the flat box walls as one continuous geometry.

Flat sides also stop the ring rotating. A high centre stone on a round shank will always drift to one side of the finger; this one stays put.

Wearing it

It's a solitaire with structure — for someone who wants the classic centre stone but finds a plain shank too quiet.

It sits high, which is the trade for the fire in the centre stone. It will catch on jumpers and it's not the ring for the gym. That's true of every raised solitaire, and we'd rather say it than not.

Against a wedding band: the boxes stop well before the base of the shank, so a straight band sits flush against the plain part with no gap.

What is moissanite?

Moissanite is a gemstone in its own right — silicon carbide — not an imitation of anything. It was first found in a meteorite crater, and the stones used in jewellery today are grown in a laboratory because natural moissanite is far too rare to set.

Two properties matter. It is 9.25 on the Mohs scale, harder than any gemstone except diamond, which is why it survives daily wear without the chipping that softer stones suffer. And its dispersion is roughly two and a half times that of diamond — it splits white light into visible spectral colour far more strongly. That is the fire you see: flashes of blue, green and orange where a diamond of the same size returns mostly white.

We say moissanite plainly on every page. It is not sold here as a diamond and never will be.

Why silver, and not gold?

Because the stone is the point. A heavy gold setting adds a great deal of money for metal that sits underneath the stone and is barely seen.

Rhodium-plated 925 sterling silver gives the same bright white-gold finish, keeps the budget in the stone and the setting, and our lifetime replating means the finish stays white for as long as you own the ring. If you would prefer this design in gold, message us on WhatsApp and we'll quote it.

Marked inside

CERELINE is engraved on the inner shank, where only the wearer sees it. Not ornament — provenance.

Made to order

Made in your size after you order, in 7 to 15 days. The back half of the shank is plain and unset, so resizing happens there and never touches a box or a stone.

Care

Rhodium plating protects the silver beneath it, and it will wear with daily use — which is why replating is free for life. Store the ring in its box when you aren't wearing it, and put it on last, after perfume and hand cream.

The recessed boxes are the catch. They're the best-protected stones on the ring and also the best at holding soap and hand cream, and because the stone sits below the rim you won't see it dulling — the box just stops flashing. Warm water, a drop of washing-up liquid, a soft toothbrush worked into each box individually, and up under the centre stone from below. Rinse and dry properly, monthly.

Remove for chlorinated water, household chemicals and fragrance.

Frequently asked questions

Does it come with a certificate?
Yes. The centre stone ships with its GRA certificate. The six shoulder stones are moissanite as well, but a separate certificate for every small stone isn't practical, so we certify the centre.

Is moissanite the same as cubic zirconia?
No. Cubic zirconia is softer, clouds with wear and has far less fire. Moissanite is 9.25 on the Mohs scale and holds its brilliance for life. They are not comparable materials and they are not comparably priced.

Will the plating wear off?
Eventually, yes — that is true of every rhodium-plated piece, at any price. Ours is free to replate for life, so it is never a reason not to buy.
