Radiant Cut Lab Grown Diamond Ring on a Domed Pave Band with Milgrain Edges

Radiant Cut Lab Grown Diamond Ring on a Domed Pave Band with Milgrain Edges

A radiant cut lab grown diamond in corner claws above a concealed halo, on a band whose top surface is domed rather than flat, pave set across the curve with milgrain worked along both edges. The stones follow the dome, so the row is convex rather than level.

Setting pave on a domed band is a different job from setting it on a flat one, and the difference is angular. On a flat surface every seat is drilled straight down and every stone faces the same way, which is why flat pave can be laid out mechanically. On a dome, the surface tilts away from the centreline as it curves, so a seat drilled straight down at the edge would leave its stone tipped sideways with half its table facing the finger. Each seat has to be drilled on the normal to the curve at that point, which means the drill angle changes continuously from the middle of the band outward. The reward is that the finished row throws light in a fan rather than in a single plane: the stones near the centre return light upward, the ones near the edges return it sideways, and the band stays bright across a much wider range of viewing angles than a flat row can manage.

Center stone details

• Stone type: lab grown diamond
• Shape: radiant cut, brilliant faceted with cut corners
• Carat weight: 2, 3, 4 or 5 carat, selected at checkout
• Color grade: E
• Clarity grade: VVS2
• Cut and polish: excellent
• Symmetry: excellent

Accent stone details

• Concealed halo: round brilliants set into the wall of the basket, visible in profile
• Band: round brilliants pave set across a domed surface, each seat angled to the curve
• Finish: milgrain worked along both edges of the dome
• Color grade: E to F
• Clarity grade: VS or better

Band details

The shank is domed across its width and pave set over the curve, with milgrain running along both outer edges. The milgrain sits at the lowest point of the curve where the band meets the finger, so it protects the outermost stones without adding height.

Metal options

Choose 925 sterling silver, or 10K, 14K or 18K gold in yellow, rose or white. Every metal is fully hallmarked. Yellow gold is shown in the photographs, where the two milgrain edges frame the curve and make the dome legible from directly above.

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, and we set out the seat angles for the curvature at your specific size.

Custom orders

We can change the carat weight, the length to width ratio of the radiant, flatten the band or remove the concealed halo. 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 set pave on a domed band
Because the stones then face outward in a fan rather than all in one plane, so the band stays bright across a much wider range of viewing angles.

Is domed pave harder to set
Yes. Each seat is drilled on the normal to the curve at that point, so the angle changes continuously across the band and nothing can be templated.

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 modest range. The pave runs most of the way round, so resizing means resetting a short section, which we do at cost after the first year.

How long does the ring take to make
Each ring is made to order. Domed pave with hand applied milgrain is slow work, so production usually takes fourteen to eighteen 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. A domed band carries a considerable number of accents, so the saving applies across the whole ring rather than only the centre.
