Wedding bands
Fitting a Band to a Marquise
The hardest shape in jewellery to nest a band against β and the one where ordering the two separately costs the most.

Short answer
A marquise almost always needs a contoured band, because the stone runs along the finger and its lower point occupies the space a straight band wants. The contour has to clear a point rather than a curve, so it must be drawn from the ring's own CAD file. Order both together; a contour modelled afterwards fits well rather than exactly.
Every elongated shape creates a band problem. The marquise creates the worst version of it, for a reason that is easy to see once it is pointed out: the thing sitting where the band wants to go is not a smooth curve. It is a point, capped in metal by a V-prong, at the lowest part of the setting.
A straight band pushed against that leaves a wedge of daylight beneath the stone, and unlike an oval there is no angle at which it nearly works.
The straight-edge test
You do not need a jeweller for this. Hold the engagement ring side-on at eye level and lay a straight edge β a ruler, a credit card, a book spine β flat against the side of the band.
- No daylight: a straight band will sit flush. Rare on a marquise, but check rather than assume.
- A sliver: some people never mind it. Decide now rather than after the wedding photographs.
- An obvious wedge: you need a contour. This is the usual marquise answer.
If the ring is not yet made, run the same test on the side elevation of the CAD render rather than the top-down view. That is the single most useful reason to insist on a side elevation, and it takes thirty seconds.
Why the marquise contour is harder to make
A contour for an oval follows a curve. A contour for a marquise has to clear a V-prong and a point, which means a tighter, more sharply defined notch cut into a specific position on the band.
Three consequences follow.
- Orientation is fixed forever. The notch is cut for one alignment. The band can only be worn one way up, and it will not fit a different marquise ring.
- Metal is thinnest at the notch. That is the point in the band with least material and most stress. Ask for the band to be thickened either side of the notch rather than made at uniform thinness β a request almost nobody makes.
- It is genuinely not wearable alone. An oval contour reads as a gently waved band. A marquise contour has a distinct V cut into it and looks like what it is β half of a pair.
Four options, honestly
| Option | Fit | Wearable alone? | Main trade-off |
|---|---|---|---|
| Contoured band | Nests exactly, if drawn from the same file | No | Tied to this one ring permanently |
| Straight band, gap accepted | Visible wedge under the point | Yes | The gap is bigger on a marquise than any shape |
| Set the marquise east-west | Often flush with a straight band | Yes | Points now aim outward; decided before casting |
| Band on the other hand | Not applicable | Yes | Two rings that never relate to each other |
The third row is the one worth pausing on, because it is a real solution that has to be chosen early. An east-west marquise spans the band rather than blocking it, so a straight band frequently fits β and a straight band is a piece of jewellery in its own right, matchable and replaceable anywhere. If a plain straight band matters more to you than the traditional orientation, say so before the ring is cast.
From our bench in Surat
A contoured band is not a product, it is a shape cut to one ring's profile. When somebody sends us a marquise from another maker and asks for a matching contour, we can do it β but the work changes completely. We are measuring and modelling from a physical object rather than reading a CAD file, and on a marquise, where the notch has to clear a point and a V-prong within a fraction of a millimetre, the difference between those two methods is visible.
So we say the same thing to every marquise customer even though it means quoting a higher figure up front: order the band with the ring. Not to secure the second sale now, but because a contour drawn alongside the ring nests exactly and one modelled afterwards does not β and on this shape more than any other, "nearly" shows.
Wear, once they sit together
Two rings in contact on one finger stay in contact for every one of the roughly five to seven thousand days they are worn. That does something.
If the band is stone-set and the engagement ring's shank is plain, the stones abrade the metal β diamond at Mohs 10, or moissanite at 9.25, against gold at roughly 2.8 is not a fair contest, and a worn track appears over a decade. Matching stone-set to stone-set, or plain to plain, is kinder. And if you mix platinum with gold, the gold wears one-directionally while the platinum displaces rather than loses metal.
Match by fineness number, not colour word. 14K and 18K yellow gold side by side read as visibly different tones, and adjacent rings are exactly where that shows.
Before you order
- Run the straight-edge test on the ring, or on the CAD side elevation.
- Order the band with the engagement ring, from the same file.
- Ask for extra thickness either side of the contour notch.
- Decide whether east-west would give you the straight band you actually want.
- Match fineness number and colour, not just colour.
- Avoid a stone-set band pressed directly against a plain shank.
- Add up the stacked width, and leave the outer position free for later.
Frequently asked questions
Does a marquise ring need a curved wedding band?
Almost always. The stone runs along the finger and its lower point sits exactly where a straight band would go, leaving a visible wedge of daylight. Confirm with a straight edge held against the side of the ring or the CAD side elevation.
Can I buy the contoured band later?
You can, but the fit will be approximate. A marquise contour must clear a point and a V-prong within a fraction of a millimetre, so one drawn from the original CAD file nests exactly while one modelled from a finished ring afterwards does not.
Is a marquise contour band wearable on its own?
Not really. Unlike an oval contour, which reads as a gently waved band, a marquise contour has a distinct notch cut into it to clear the point. It also only fits one way up and will not fit a different ring.
How do I get a straight band with a marquise?
Set the marquise east-west. Turned across the finger the stone spans the band rather than blocking it, so a straight band often fits flush. It has to be decided before casting, and it means both points then aim outward, which makes V-prongs mandatory.
Is the notch a weak point in the band?
It is where the band has least metal, so it deserves attention at the design stage. Ask for extra thickness either side of the notch rather than a band made at uniform thinness β it costs very little and almost nobody requests it.
Order the ring and the band together
Both are made to order in our Surat workshop and drawn from one file, so the contour nests exactly rather than approximately.
