Oval Art Deco Moissanite Bridal Set: What to Know Before You Order
Our most-ordered bridal set, explained from the bench: how the oval changes shape as it grows, what the Art Deco halo does to moissanite, and how to choose the metal.
Written by the Mapple Gems workshop, Surat Β· Updated 13 October 2026
Short answer: The 3.50 CT Oval Art Deco Bridal Set pairs an oval moissanite with an Art Deco halo and pavΓ© shoulders, plus a matching band, made to order in 925 silver or solid 10K, 14K or 18K gold. Customers have ordered it three times, from 2 to 4 carats. The detail to check first is the millimetre size: the oval gets noticeably slimmer above 2.5 carats.
Some designs sell once and disappear. This set keeps coming back. It has been ordered in sterling silver, in 14K yellow gold and in 10K white gold, and two of those three customers chose the largest stone we offer. That tells us something about who buys it β people who want a big, decorative oval with a vintage frame, and a band that is made to sit against it.
This guide covers what we would want a customer to know before ordering: the size options in millimetres, what the halo changes, the metal decision, and why the band is made in the same run as the ring.
The oval changes shape as it grows
Carat figures for moissanite are a convenience. Moissanite is about 15% less dense than diamond, so it is sold by millimetres and a diamond-equivalent weight, and the millimetres are what you actually see. On this set, the length-to-width ratio is not fixed across the size options β and that changes the look more than the carat number does.
| Size option | Centre stone | Length : width | How it reads |
|---|---|---|---|
| 2 carat | 9 Γ 7 mm | 1.29 | Full, soft oval |
| 2.5 carat | 10 Γ 8 mm | 1.25 | The roundest option |
| 3 carat | 12 Γ 8 mm | 1.50 | Long and slim |
| 3.5 carat | 12 Γ 8.5 mm | 1.41 | Classic elongated oval |
| 4 carat | 12.5 Γ 8.5 mm | 1.47 | Elongated, finger-slimming |
Most people picture an oval somewhere between 1.35 and 1.45. The 3.5 carat option sits right in that band. The 2 and 2.5 carat options are fuller and closer to round; the 3 carat is the slimmest of all. If you have a photograph of an oval you love, measure its ratio before choosing a size β it matters as much as the carat figure.
What the Art Deco halo does to a moissanite
A halo is a ring of small round stones around the centre. It does two things. It makes the centre read larger β a row of accents around 1.3 mm wide adds roughly 2.6 mm to the face-up width β and it multiplies sparkle, because every one of those small stones disperses light too.
That second point matters more with moissanite than with diamond. Moissaniteβs dispersion is 0.104 against diamondβs 0.044, so it throws more coloured fire. A halo adds twenty to forty more points of light around an already lively stone. If you love sparkle, this set delivers it. If you want something calmer, warm metal is the best lever: yellow gold reflects into the stone and visibly softens the rainbow effect.
The honest trade-off is maintenance. A solitaire has four to six settings to check; a halo set has dozens. None of them is a weakness on its own, but prongs and beads thin slowly with wear, so a bench check every two years is part of owning a halo ring.
Silver or gold for a halo set
Moissanite is Mohs 9.25. Sterling silver is about 2.6 and gold about 2.8 β both far softer than the stone. In silver, the small prongs and beads of a halo are the part that wears first, while the stone stays perfect. That makes silver a sensible choice for trying a design or for a ring worn on occasions, and a weaker choice for a halo ring worn every day for years. For daily wear we recommend 14K gold: it is harder than 18K and holds small settings well.
If you choose white gold, remember it gets its bright white colour from rhodium plating, which needs renewing every one to two years. Yellow and rose gold never need it.
From the workshop
Two of the three customers who ordered this set chose the 4 carat option, a 12.5 Γ 8.5 mm oval. With the halo added, the head measures roughly 15 Γ 11 mm. On a smaller finger that covers most of the space between the knuckles. Before choosing the largest size, cut a paper oval at about 15 Γ 11 mm and hold it on the finger where the ring will sit. It is the cheapest test we know, and it prevents more size regrets than any product photograph β macro photography always makes a ring look bigger and brighter than it reads on a hand.
Why the band is made with the ring
A halo ring rarely takes a straight band flush against it. The halo sits wider than the shank, so a band bought separately often leaves a gap or rubs against the halo edge. Making the set together means the band is fitted to this ringβs profile in one production run and arrives in one shipment.
One care rule follows from that. Stone-set pieces abrade the metal they touch, because the stones are many times harder than gold. Wear the two rings together, but store them apart β one pouch each.
Before you order: a short checklist
- Choose the size by millimetres and shape, using the table above, not by carat alone.
- Do the paper test at the full head size, halo included.
- Choose 14K gold for daily wear; consider silver for occasional wear or to try the design.
- Decide whether you want more fire (white metal) or a calmer look (yellow or rose gold).
- Approve the CAD preview with the side view in mind β profile height is fixed once the ring is cast.

Frequently asked questions
Is the centre stone a diamond?
No. It is moissanite β silicon carbide, Mohs 9.25, refractive index 2.65β2.69 and dispersion 0.104. It is hard enough for daily wear and shows more coloured fire than a diamond.
What sizes does the Oval Art Deco Bridal Set come in?
Five centre-stone options: 2 carat (9 Γ 7 mm), 2.5 carat (10 Γ 8 mm), 3 carat (12 Γ 8 mm), 3.5 carat (12 Γ 8.5 mm) and 4 carat (12.5 Γ 8.5 mm).
Which metal is best for wearing this set every day?
14K gold. It is harder than 18K and holds the small halo settings well. Sterling silver is softer, so its small settings wear sooner; it suits occasional wear or trying the design.
Does the halo make the oval look bigger?
Yes. A halo row adds roughly 2.6 mm to the face-up width and length, so a 12.5 Γ 8.5 mm oval reads at about 15 Γ 11 mm across the whole head.
Why buy the ring and band as a set?
A halo ring is wider than its shank, so a separately bought band often leaves a gap. A set is made in one run so the band is fitted to the ringβs profile.
