What People Mean By "Dutch Marquise Diamond"
Searches for "dutch marquise diamond" usually come from two different places, and it helps to know which one you are in before you start sourcing.
Some people mean a historical cutting style: an older, often chunkier marquise shape with a shorter length-to-width ratio and a thicker crown, associated with early marquise cutting traditions and sometimes used loosely to describe antique or estate marquise diamonds. Others simply mean a marquise cut diamond, full stop, and "Dutch" has gotten attached to the search term through years of imprecise listing titles on resale and auction sites.
There is no single certified grading category called "Dutch marquise" at labs like GIA or IGI. It is a trade term, not a formal cut classification, which is exactly why it causes confusion when a retailer or private buyer tries to order one.
Our own cutting team's take: when a customer asks for a "Dutch marquise," we ask for a photo or a target length-to-width ratio before we quote anything. The word alone tells us almost nothing about the actual proportions they want.
The Marquise Shape, Explained Properly
A standard marquise diamond is an elongated shape with pointed ends on both tips, somewhere between a football and an eye in outline. Modern marquise cuts are typically faceted with a length-to-width ratio between 1.75:1 and 2.25:1, which reads as elegant and slender on the finger.
What people call a "Dutch marquise" tends to be shorter and wider, closer to 1.5:1 or even 1.4:1, with a noticeably higher crown and a bulkier overall profile. This older proportion was common before cutters refined marquise faceting for better light return and a slimmer silhouette.
Here is how the two profiles compare side by side:
| Feature | Modern Marquise | "Dutch" Marquise (older style) |
|---|---|---|
| Length-to-width ratio | 1.75:1 to 2.25:1 | 1.4:1 to 1.6:1 |
| Crown height | Moderate | Higher, chunkier |
| Overall look | Slender, elongated | Shorter, fuller |
| Finger coverage | More length per carat | More width per carat |
| Common era | Current fine jewelry standard | Older cutting tradition, revived on request |
Neither shape is objectively better. It is a matter of what proportion flatters the finger and the design, and that is a conversation worth having before you commit to a stone.
Why This Confusion Matters When You Are Sourcing
If you run a jewelry shop and a customer asks for a Dutch marquise, ordering the wrong proportion wastes time and sometimes a deposit. A supplier who does not ask clarifying questions will often just send you a standard marquise and call it close enough.
For retailers buying wholesale, the fix is simple: specify the length-to-width ratio in the purchase order, not just the shape name. For private customers commissioning a custom ring, the fix is a sketch, a reference photo, or a sample ratio on paper before cutting begins.
This is the kind of detail that separates a supplier who cuts to spec from one who ships whatever is closest in stock.
Lab-Grown Marquise Diamonds: What's Actually Available
Lab-grown diamonds now cover the full range of marquise proportions, from the elongated modern cut to the shorter, fuller profile some buyers call Dutch marquise. Because lab-grown rough is grown to a known size and clarity profile rather than mined and found, cutters have more flexibility to target a specific ratio without sacrificing carat weight to waste.
Typical lab-grown marquise pricing, by carat weight:
- 0.50 to 0.75 carat: generally $500 to $1,100 per stone depending on color and clarity grade
- 1.00 to 1.50 carat: generally $1,200 to $2,800 per stone
- 2.00 carat and above: generally $3,500 and up, with price climbing faster per carat as size increases
These bands assume near-colorless to colorless grades (G to F) and VS to VVS clarity, the range most retail and custom engagement buyers land in. Fancy color lab-grown marquise stones, or anything above 3 carats, needs a direct quote because availability and pricing swing more at that end.
Custom-Cutting a Dutch Marquise to Exact Proportions
Because "Dutch marquise" is not a standardized cut, the only reliable way to get exactly what a customer has in mind is to custom-cut it. Bespoke Carat works this way regularly for unusual and historical shape requests, cutting lab-grown rough to a specified length-to-width ratio rather than pulling from generic marquise inventory.
The process looks like this:
- Define the ratio. The client or retailer supplies a target length-to-width ratio, often anchored to a reference photo or an existing antique piece.
- Select the rough. Rough is matched to the target carat weight, accounting for the extra waste a shorter, fuller marquise profile produces compared to a standard elongated cut.
- Pre-cut proofing. For larger or higher-value stones, a cutting plan or model is reviewed with the client before the final cut.
- Cutting and faceting. The stone is cut and faceted to the agreed proportions, then polished.
- Grading and certification. The finished stone is graded and documented before shipping.
A length-to-width ratio of 1.5:1 instead of 2:1 on the same carat weight can mean a visibly different finger coverage. Get this number right before cutting, not after.
Typical turnaround for a custom-cut marquise, Dutch-proportioned or modern, runs 3 to 5 weeks for a single stone and 5 to 8 weeks for a matched pair or small batch, depending on carat size and how much proofing the client wants before final cutting.
Minimum Order Quantities and Who This Serves
Bespoke Carat serves two distinct buyers, and the ordering structure reflects that.
Independent jewelry shops and retailers buying for stock or for a specific client commission typically order single stones or small batches. There is no large-volume minimum required to access wholesale pricing on custom-cut shapes, which matters for a shop that cannot afford to tie up capital in a dozen identical unusual cuts.
Private clients commissioning a single engagement ring or custom piece order one stone at a time, matched to their design. Pricing and lead time scale the same way whether the order comes through a retailer's account or directly from an individual.
If a retailer wants a recurring supply relationship rather than one-off custom orders, that is a separate conversation about standing wholesale terms, and it is worth raising directly when requesting a quote.
Alternatives Worth Considering
Not every customer who says "Dutch marquise" actually needs that specific historical proportion once they see the options side by side. A few shapes worth showing as alternatives:
- Standard round diamonds remain the most universally available and easiest to resize or rematch later, useful if the marquise request was really about getting something distinctive rather than the shape itself. See the full range of Round Diamonds for comparison.
- Trapezoid cuts work well as side stones alongside a marquise center and give a similarly elongated, geometric feel. A matched pair, like this Trapezoid Cut Lab Grown Diamond Matching Pair, suits a three-stone design.
- Pentagon cuts offer a different kind of unusual silhouette for a client who wants something unmistakably custom rather than historically specific. See the Pentagon Cut Lab Grown Diamond for an example.
- Flame cuts push further into fancy-shape territory for a client who came in asking about Dutch marquise but really wants a conversation-starting centerpiece. The Flame Cut Lab Grown Diamond is one option worth showing alongside a marquise quote.
Showing a customer two or three real options next to their original request usually resolves the ambiguity faster than explaining cut history.
Certification and Standards
Every stone Bespoke Carat supplies, standard shape or custom cut, ships with grading documentation covering carat weight, color, clarity, and cut quality. For a non-standardized shape like a Dutch marquise, documentation matters even more because there is no industry benchmark proportion to compare against.
The IGI and GIA both grade lab-grown diamonds on the same four Cs framework used for natural stones, with lab-grown status clearly noted on the report. Buyers should expect that disclosure as standard, not as an upcharge or a special request.
For a custom-proportioned marquise, ask the supplier whether the certificate will note the actual length-to-width ratio achieved, since that number is the only reliable way to confirm the stone matches what was requested.
Packaging and Shipping
Lab-grown diamonds, whether a single custom-cut stone or a wholesale order for a retail shop, ship insured and trackable. For international orders into Canada or elsewhere, customs documentation and duty handling should be confirmed before the order ships, not after it is already in transit.
Retailers ordering regularly benefit from asking about consolidated shipping for multi-stone orders, which reduces per-shipment cost compared to ordering each custom piece separately.
Frequently Asked Questions
Is a Dutch marquise diamond a recognized grading category?
No. GIA and IGI grade marquise diamonds as a shape but do not use "Dutch marquise" as a formal classification. It is a trade term describing an older, shorter, fuller marquise proportion.
What length-to-width ratio should I ask for if I want this look?
Aim for 1.4:1 to 1.6:1 if you want the shorter, fuller historical look, compared to 1.75:1 to 2.25:1 for a modern marquise. Bring a reference photo if possible, since the ratio alone can still be interpreted differently by different cutters.
Can lab-grown diamonds be cut to this older proportion?
Yes. Bespoke Carat cuts lab-grown rough to custom length-to-width ratios on request, including shorter, fuller marquise proportions, with typical turnaround of 3 to 5 weeks for a single stone.
Is a custom-cut marquise more expensive than a standard one?
Custom cutting generally adds a modest premium over buying from standard inventory, mainly reflecting cutting time and rough selection rather than the shape itself. Get a direct quote based on carat weight and target ratio rather than assuming a flat markup.
Do I need a minimum order to get wholesale pricing on custom shapes?
No large minimum order is required for single stones or small batches on custom-cut shapes. Retailers looking for ongoing wholesale supply terms should raise that separately when requesting a quote.
How do I make sure the stone I receive matches what I asked for?
Request that the grading certificate or accompanying documentation state the actual length-to-width ratio achieved, and confirm this before the stone ships rather than after delivery.
