A solitaire with edges.

Most solitaires are built from curves — round stone, round collet, round shank. This one is cut from angles. The setting meets the stone in flat kite-shaped panels that form a hexagon around the girdle, so the round brilliant sits inside a geometric frame rather than a circular cup.

The effect is subtle and it does a specific thing: the flat panels catch light as solid planes while the stone throws it in points. Metal and stone read differently instead of blending into one bright shape. It's why this ring looks sharper than its carat weight suggests.

The stone

A single round brilliant, held in four double prongs — pairs rather than singles, at each corner.

Double prongs are slower to make and use more metal, and they're worth both. Two claws per corner means the stone is held at eight points instead of four, so if one is ever knocked out of true the stone doesn't move. They also sit lower and wider than single claws, which keeps them from catching on knitwear.

What you can only see from the side

Turn the ring side on and the head opens into a cathedral arch — and there, set inside the gallery beneath the centre stone, is a stone you cannot see when the ring is on.

It faces down toward the finger. Nobody else will ever notice it. That's the point: it's an old jeweller's habit of putting something under the setting that only the wearer knows about, and it's the detail people tell their friends about years later.

It isn't only sentiment. Set into the open gallery, it catches light travelling up through the arch and passes it into the base of the centre stone.

The shoulders

Two rows of pavé run down each shoulder, edged with milgrain — that fine beaded line worked along the border by hand. Milgrain is a Victorian technique and its purpose is practical: it softens the hard edge where metal meets air, so the band catches light along its entire length rather than only where stones sit.

The shoulders split as they approach the head, forming a V that lifts the stone clear. The inside is plain and comfort-rounded.

Wearing it

This is an engagement ring for someone who finds most engagement rings a bit soft. It has the clarity of a plain solitaire and the detail of something far more ornate, and it manages both because the detail is in the structure rather than added on top.

It takes a plain band beside it well. The split shoulders leave a clean line at the base where a wedding band sits flush.

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. Pavé runs partway down the shoulders and the base of the band is plain, so modest resizing later is possible.

Care

Rhodium plating doesn't tarnish, but it does wear. With daily use expect to need replating every 12 to 18 months — sooner if you're hard on your hands. It's 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.

Pay attention to the gallery when you clean it. The hidden stone sits where hand cream and soap collect, and it's the one part you won't notice going dull because you can't see it. Once a month, warm water, a drop of washing-up liquid, a soft brush worked up into the arch from underneath, rinse and dry fully.

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 pavé and the hidden gallery stone 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, including white gold. With daily wear expect 12 to 18 months. Ours is free to replate for life, so it is never a reason not to buy.

How do I find my ring size?
We make sizes 10 to 20. Use the size guide on this page, or message us on WhatsApp at +92 371 4323294 and we'll walk you through measuring.
