Matching Custom Moissanite Wedding Bands: The Gap and Contour Problem

Matching Custom Moissanite Wedding Bands: The Gap and Contour Problem

A bride in Rotterdam bought a moissanite solitaire online, then ordered a plain wedding band off the shelf. On her wedding day the band sat with a 1.5 mm gap next to the cathedral shoulder of the solitaire, and in photos the set looked unfinished. She came back to us six months later to have the band remade as a contour. The gap was not the goldsmith's fault; the off-the-shelf band was never cut to her ring's shoulder. Matching custom moissanite wedding bands is measured against the specific engagement ring, not a generic curve on a template.

Below are the three band profiles we build to sit against a moissanite solitaire, with the gap, shoulder clearance and sizing adjustment we measure before the CAD opens.

The straight band: only for flat shoulders

A straight band sits flush next to an engagement ring only when the solitaire has low, flat shoulders that run parallel to the finger. Most cathedral and raised solitaire shoulders curve up, and a straight band will leave a gap at the bottom or the top. We quote a straight band only after seeing the engagement ring profile. The straight band is the cheapest to build, at roughly the same labour as a plain band, but it fits maybe 30 percent of the solitaires we see. Our wedding band matching overview shows the shoulder profiles that accept a straight band.

The contour band: the curved fit

A contour band is curved to hug the engagement ring's shoulder, leaving the top edge touching and the bottom edge following the curve. We measure the shoulder height and the under-gallery radius on the actual ring, then mill the band's inner curve to match within 0.2 mm. Build cost runs about 20 percent above a straight band because the curve is custom-milled, not a stock profile. The contour is the default for cathedral solitaires. Buyers should read our contour and notched band write-up before choosing, because the contour does not solve a high-set ring.

The notched band: for high-set solitaires

When the solitaire sits high off the finger on a raised gallery, a contour still leaves a gap under the head. The notched band cuts a scoop out of its top edge to clear the gallery rail. The notch weakens the band slightly, so we step the band width to 2.2 mm minimum on a notched build and warn against thin 1.8 mm notches. Notched bands are the most custom of the three, and they require the engagement ring in hand or an exact shoulder drawing. Our his-and-hers matching sets write-up covers how the notch carries across to the men's band.

Sizing the band after the engagement ring

A matched band should be sized on the same finger, worn next to the engagement ring, because the two bands together take up knuckle room. We ask buyers to size the band 0.25 size looser than the solo engagement ring to allow for the stack. Resizing a contour band after delivery is harder than resizing a straight band because the curve shifts when the shank is stretched; we quote the band size at first proof. The resizing limits are detailed in our resizing after delivery guide.

Metal matching across the set

A platinum engagement ring paired with a white-gold wedding band will yellow over time because rhodium wears off. We match metal across the set: platinum to platinum, 14k white to 14k white. If the buyer wants the band in a different metal, we disclose the wear difference. Metal options across our range are listed in our metal alloy options write-up, and fineness follows FTC 16 CFR 23 jewellery marking rules so the karat stamp reads correctly on the band inside wall.

How tight should a matched wedding band sit?

The top edge should touch the engagement shoulder with no visible daylight. A 0.2 mm clearance is acceptable; anything larger reads as a gap in photos.

Can I buy a wedding band without the engagement ring?

For a contour or notch, no. We need the shoulder profile. A straight band can be built to size alone, but only if the solitaire has flat shoulders.

Does a notched band wear weaker?

Slightly. We build notches in 2.2 mm minimum width and avoid thin 1.8 mm notches, which flex and lose their curve over time.

Should the band match the engagement metal exactly?

Yes for white tones, so rhodium wear does not yellow the pair. Platinum to platinum and 14k white to 14k white keep the set matched.

Why we measure the set, not the ring

A wedding band fitted to a bare solitaire sits differently once the engagement ring is on the finger. We ask buyers to send the engagement ring or a traced shoulder profile so the contour is milled to the ring they actually sell, not a generic curve. A band that fits on a flat table can bind on a knuckle once the two rings stack.

Send us the engagement ring shoulder profile and finger size. We return a band type, gap measurement and notch clearance on the CAD before wax. Ask us to spec your next matched moissanite wedding band.

Frequently Asked Questions

Is moissanite a good diamond alternative for retail buyers?

Yes for price-sensitive customers who want brilliance and hardness. Moissanite ranks 9.25 on the Mohs scale, holds up to daily wear and costs a fraction of a natural diamond of the same size, so it resells fast in bridal and fashion lines.

What is the minimum order for wholesale moissanite?

MOQ starts at 50 pieces per design for stock items. Custom cuts and private-label settings usually start at 100–300 pieces depending on the mold.

Do you provide certificates with moissanite stones?

Yes. Every parcel ships with GRA or IGI documentation listing carat weight, color grade and cut. We recommend passing the certificate to your end customer for trust.

How long does sample and bulk production take?

Samples ship in 3–5 days. Bulk runs take 15–20 days under 500 pieces, and 25–30 days for custom work.
