Loose Lab-Grown Diamonds / Business sourcing
Specify marquise lab-grown diamonds through aligned points, balanced shoulders, face-up appearance and the orientation of your ring or earring design.
Preferences are a brief, not a live inventory selection.
A product brief, not just a grade list
Marquise lab-grown diamonds introduce a long outline with two pointed ends into the product plan. A usable sourcing brief identifies how the points align, how the shoulders curve and whether the design places the stone north-south, east-west or within a multi-stone layout. Length-to-width ratio is useful, but it cannot describe every contour or central contrast pattern. For pairs, define orientation and review the proposed stones together. MEITUO coordinates the product and supplier discussion around those requirements. Example dimensions are planning references only; the actual diamond’s grades, report, condition, appearance and availability must be reviewed with the quotation before an order is agreed.
01 / Define the actual requirement
Separate the product description, sample values and information that must be confirmed for the actual selected goods.
| Material | Laboratory-grown diamond; material identity is separate from the shape name. |
|---|---|
| Shape / cutting style | Marquise brilliant; cutting style as reported |
| Supply status | Sourcing request; actual availability is confirmed against your brief. |
| Illustrative carat weight | 2.00 ct per stone; example only, not a listed inventory item. |
| Illustrative dimensions | 12.60 × 6.40 × 4.10 mm (L × W × D); not measurements of an offered stone. |
| Proportion / outline | 1.97 in the illustrative configuration; a ratio does not replace assessment of the two points and curved sides. |
| Color & clarity | Request your preferred range; final individual grades are as reported. |
| Mounting review | Point/corner support, orientation and clearance should be approved by the setter for the actual stone. |
| Cut / polish / symmetry | Use the fields and terminology on the actual issuing laboratory’s document. |
| Growth method | CVD or HPHT as documented for the selected diamond; state any method requirement. |
| Post-growth treatment | Confirm the disclosed treatment information separately from the growth-method label. |
| Report & correspondence | Agree laboratory, document coverage and any supplied inscription correspondence. |
| Order unit & matching | Each or a selected pair; state each-stone and total weights, dimensions and acceptance criteria. |
| MOQ / price / lead time | Confirmed by quotation after specification, quantity, destination and availability review. |

02 / Choose against the design
Use these product-specific checks to make your quotation request more precise.
Inspect point alignment and the balance of the curved sides. A long ratio alone does not establish a symmetric marquise outline. Send a visual reference if the design depends on a particular shoulder shape or a narrowly defined silhouette.
Orientation changes the finished design and should be included in the sourcing request. For earrings or asymmetric layouts, provide a small drawing showing the direction of each stone. Do not leave point placement to be inferred from the shape name.
Review consistent face-up images and a movement view when available for the shortlisted diamond. Central contrast may be conspicuous in some viewing conditions. Agree on the desired visual standard rather than using an unsupported statement that every marquise in a grade band looks the same.
Ask the setter which point supports, seat dimensions and depth clearance the design requires. A retained mount can impose restrictions that are not apparent from carat weight. Confirm the selected stone against those requirements before approving the goods.
03 / Plan from the finished design
The finished setting or production workflow determines which measurements and matching decisions belong in the enquiry.
APPLICATION 1
For an east-west marquise ring, state the horizontal orientation and the setting’s overall length, seat and depth limits. The two points must be considered with the setter’s support requirements. Review shoulder balance and face-up appearance in the selected diamond before completing the mount; a vertical-ring brief should not be assumed to describe this layout.
Brief This Application
APPLICATION 2
A botanical band uses repeating marquise stones as directional elements, so the full layout matters more than a single center-stone weight. Provide the stone count, leaf-like orientations, spacing and dimensional requirements for the design. Confirm suitable smaller sizes separately and agree how contour and appearance will be matched across the band.
Brief This ApplicationADDITIONAL DESIGN USE
Pairs need aligned design logic as well as similar grades. State whether points should share a direction or form a mirrored layout, then compare dimensions, shoulder shapes and face-up appearance. Keep per-stone weight and combined weight separate in the quote and in the approved selection record.
Brief This Application04 / Your buying model
Coordinate a long two-pointed center with its mount.
Include in the RFQ: Send orientation, both-point support requirements, actual dimensional limits and contour reference.
Work with the marquise as a directional design element.
Include in the RFQ: Provide the complete layout, spacing, orientation and any matching relationships between stones.
Develop marquise pairs with a coherent silhouette.
Include in the RFQ: Specify each-stone and total weights, length and width tolerances, point directions and visual acceptance.
05 / Qualitative procurement scenarios
Use a specific business scenario to prepare an enquiry. These examples do not assert national preferences, market size or confirmed orders.
| Market | Buying scenario | RFQ focus |
|---|---|---|
| United States | Directional bridal and earring assortment | Orientation and comparable face-up views |
| United Kingdom | Bespoke pointed-stone commissions | Point support and outline approval |
| Australia | Design-led made-to-order collections | Layout records and approval schedule |
A retailer planning marquise rings and earrings can create different RFQ lines for vertical centers, east-west centers and matched pairs. The actual stone’s dimensions and visual material should accompany the shortlist. This is an assortment-planning example, not a claim about the scale or ranking of American marquise demand.
A jeweller interpreting a client sketch can separate the desired silhouette from the mounting’s fixed support and clearance constraints. Agree on both ends of the stone as part of the fit review. This is a qualitative procurement scenario rather than a universal British design preference.
A studio using marquise stones as directional elements can retain the approved drawing and outline criteria with the buying file. Include whether a future reorder must match that silhouette closely. Goods and delivery timing still require individual quotation; no national sales data is inferred from the scenario.
06 / A practical comparison
Compare the properties that change the purchasing decision, then review the actual selected stones or parcel.
| Buying consideration | Marquise brilliant | Oval brilliant |
|---|---|---|
| Ends | Two pointed ends. | Two rounded ends. |
| Outline check | Point alignment, curved sides and shoulder balance. | Rounded-end balance, curved sides and shoulders. |
| Proportion reference | Often a longer silhouette; specify actual target dimensions. | Specify actual length, width and ratio for the design. |
| Mount briefing | Include support and clearance at both points. | Include the continuous curved seat outline. |
| Visual review | Review central contrast and the individual light pattern. | Review central contrast and the individual light pattern. |
| Substitution | A marquise outline is not an oval fit substitute. | An oval outline is not a marquise fit substitute. |
08 / Before you source
No. A marquise has two pointed ends, while an oval has rounded ends. Their contour, mounting requirements and appearance differ even if length, width or weight are similar. Name the intended shape clearly and provide an outline reference if the design cannot accept a substitute.
Choose the ratio in relation to the finished design rather than treating one number as a universal quality target. Record length and width, then review point alignment and side curvature separately. The illustrative ratio is 1.97, but an actual sourcing request can discuss a different outline.
Yes, state that orientation in the inquiry and include the mount or layout drawing. Confirm length, width, depth and support at both points with the setter. A stone suitable for one orientation is not automatically a fit for a retained head designed around different dimensions.
Review length, width, shoulder contour, point alignment and face-up appearance together. Clarify the intended directions in the finished earrings or layout. Each-stone and total weights should be stated separately, with matching acceptance agreed for the actual pair before the order is confirmed.
State the required issuing laboratory in the inquiry, then review the actual document for the selected diamond. Check correspondence with the goods and record growth method and post-growth treatment disclosure separately. Laboratory service formats differ, so use the fields actually supplied rather than copying one grading template across every stone.
Those terms are confirmed after the sourcing requirements and proposed goods have been reviewed. Include the number of stones or pairs, specification, destination and required date in the brief. This page does not promise a universal minimum, a fixed price, stock availability or a delivery date before quotation.
