Radiant Cut Lab Grown Diamond Ring with Graduated Marquise Accents Along the Shank

Radiant Cut Lab Grown Diamond Ring with Graduated Marquise Accents Along the Shank

A radiant cut lab grown diamond in four claws, with marquise accents running lengthwise down each side of the band and reducing in size as they travel away from the centre. The metal between them is minimal, so the shank reads as a tapering ribbon of diamond rather than a band with stones on it.

Laying marquises lengthwise along a shank creates a problem that is invisible in a photograph and obvious on a hand. A band curves, so a stone set flat into it at the shoulder faces upward while a stone set flat further along faces sideways, away from anyone looking at the ring. Set naively, the outer accents go dark exactly when the wearer holds their hand out. The fix is to tilt each accent slightly against the curve, so that every table stays roughly perpendicular to the viewer instead of perpendicular to the band it sits in. The angle changes stone by stone, increasing as the row descends, and it is worked out for each ring size because the curvature of the shank changes with circumference. Done properly the whole row lights at once. Done as a straight repeat, half of it is dark at any given moment.

Accent stone details

• Clarity grade: VS or better

Band details

The shank is fine, with only a bead of metal between one accent and the next through the upper half, and left plain below. Because the marquises are graduated, the band appears to taper away from the centre stone even though the metal itself stays a constant width.

Metal options

Choose 925 sterling silver, or 10K, 14K or 18K gold in yellow, rose or white. Every metal is fully hallmarked. White gold is shown in the photographs, where the matched tone lets the row of marquises read as one continuous tapering shape.

Ring size

The ring is made to your finger size. Select your size at checkout. If you are unsure, we will send you a printable size guide before we begin work, since the tilt angle of each accent is calculated for your specific size.

Custom orders

We can change the carat weight, the length to width ratio of the radiant, the number of accents or set the marquises crosswise instead. Write to us through https://mapplegems.com/pages/contact and our workshop will prepare a quotation and a rendering before any metal is cut.

Frequently asked questions

Is a lab grown diamond a real diamond
Yes. It is carbon in the same crystal structure as a mined diamond, with the same hardness and the same optical properties, graded on the same scales.

Does the ring come with a certificate
Yes. An IGI certificate for the center stone is included at no extra charge.

Why are the accents tilted
Because the band curves. Without a tilt, accents further from the centre would face sideways and go dark when the hand is held out. Tilting them keeps the whole row lighting together.

Are the marquise points protected
Yes. Each point sits inside a claw and the accents are graduated so no tip stands proud of its neighbour.

What is a radiant cut
A cut cornered rectangle faceted like a brilliant rather than a step cut, giving the outline of an emerald cut with the fire of a round.

Can this ring be resized
Within a moderate range, working in the plain lower shank. Larger changes alter the curvature the accents were angled for, and we will advise you if that applies.

How long does the ring take to make
Each ring is made to order. Production usually takes twelve to sixteen working days before dispatch.

Why buy a lab grown diamond

A lab grown diamond gives you a larger stone and a higher colour and clarity grade for the same budget, with a traceable origin and no mining. Graduated accents only look graduated if they are matched in colour, which is far easier to guarantee with grown stones than with sourced ones.
