Loose Lab-Grown Diamonds / Business sourcing
Source loose oval center stones and matched pairs for bridal collections, bespoke jewellery and repeat business orders.
Preferences are a brief, not a live inventory selection.
A product brief, not just a grade list
Oval lab-grown diamond sourcing combines an elongated silhouette with the practical requirements of a ring, pendant or matched earring pair. Weight alone does not tell you how the outline will read in a setting: length, width, shoulder shape and depth all belong in the brief. When reviewing a proposed stone, consider face-up images and movement alongside the actual grading information. A dark central bow-tie appearance should be discussed through visual evidence rather than an unsupported promise that every oval is identical. MEITUO coordinates the sourcing conversation around the agreed design, documentation and purchasing requirements; final specification and availability are confirmed with the selection.
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 | Oval brilliant |
| 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 | 10.20 × 7.10 × 4.40 mm (L × W × D); not measurements of an offered stone. |
| Proportion / outline | 1.44 in the illustrative configuration; outline preference is design-specific, not a universal quality grade. |
| Color & clarity | Request your preferred range; final individual grades are as reported. |
| 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.
A length-to-width ratio describes the silhouette, but rounded ends and shoulder shape still influence the outline. Share a reference image or setting drawing so the sourcing request describes the intended look instead of assuming that one ratio produces every design effect.
Compare consistent face-up views and a video when available. The central pattern can change with viewing and lighting, so define the visual standard using the proposed diamond. Do not substitute a report summary for a review of the stone’s appearance.
Record length, width and depth, plus any clearance or seat constraints from the setter. Ovals with the same weight can have different face-up dimensions. A shortlist for an existing head should therefore be built around dimensional fit as well as grade and price.
For earrings, compare both stones together for contour, ratio, length and width, then review color appearance. Similar report grades are useful information but cannot describe every visible difference between two elongated shapes. Agree on matching acceptance before ordering.
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 oval solitaire ring, start with the center outline and the seat that will support it. Record length, width, depth and the desired face-up proportion before comparing stones. Approve the actual diamond with the setter so the head and prong positions suit the selected outline rather than only a target carat weight.
Brief This Application
APPLICATION 2
For a pendant, describe the oval’s intended direction, the visible outline and how the bail and prongs relate to the stone. Include dimensions and an appearance reference with the request. Review the proposed diamond before completing a closely fitted pendant mount; the example illustrates a loose-stone application rather than a supplied finished item.
Brief This Application
APPLICATION 3
Use the CAD drawing, setting limits and approved appearance reference to build a repeatable oval stone list. Keep the agreed tolerances with the buying record. Subsequent sourcing can begin from that brief, while individual goods and any differences remain subject to review.
Brief This Application04 / Your buying model
Find a center stone around a client’s oval reference or retained mount.
Include in the RFQ: Include target outline, length and width constraints, weight preference and the actual document requirement.
Develop a coherent elongated-stone collection without relying on weight alone.
Include in the RFQ: Send a setting drawing, proportion reference, application and repeat-order expectations, plus any matching needs.
Build oval selections against clear acceptance criteria.
Include in the RFQ: Separate single stones from matched pairs; list tolerance, report and image requirements alongside quantity.
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 | Digital bridal center-stone selection | Report data and comparable face-up views |
| United Kingdom | Bespoke oval ring development | Mount fit, outline reference and surrounding stones |
| Australia | Made-to-order oval collections | Approval timing and repeat specification |
For a bridal business presenting oval choices online, pair the stone’s individual grading data with consistent imagery and dimensions. Ask whether video is available for the proposed shortlist. This is an example of an RFQ built around digital selection, not a claim that every American buyer uses the same process.
An independent jeweller working from a client sketch can define length, width, depth and side-stone layout before comparing ovals. Clarify which dimensions are fixed and which can be adjusted in a new setting. This is a qualitative buying scenario, not a national demand ranking or customer case.
A made-to-order collection can keep the approved oval contour and dimensional tolerance with its design file. State when stone selection must be complete, where the order would be delivered and whether repeats are planned. Actual goods and timing require quotation; no market growth rate is implied here.
06 / A practical comparison
Compare the properties that change the purchasing decision, then review the actual selected stones or parcel.
| Buying consideration | Oval brilliant | Round brilliant |
|---|---|---|
| Outline | Elongated; compare ratio and contour. | Circular; compare diameter and proportions. |
| Fit information | Length, width, depth and shoulder outline. | Diameter, depth and head dimensions. |
| Visual assessment | Check outline balance, central bow-tie appearance and light return. | Check radial symmetry, proportions and light return. |
| Pair matching | Compare both dimensions and the elongated silhouette. | Compare diameter and overall visual balance. |
| Size and cost | Depend on the actual stone and quotation. | Depend on the actual stone and quotation. |
| Best choice | The outline suited to the finished design. | The outline suited to the finished design. |
08 / Before you source
There is no single ratio that suits every design. Divide length by width to describe the silhouette, then compare it with the mount or appearance reference. The illustrative configuration is 1.44; that number alone does not describe light return, bow-tie appearance or overall quality.
Share the setting’s length, width, depth clearance and allowable tolerance with the request. A desired weight by itself is not enough to establish fit. Review the proposed stone with the setter before accepting it, especially where the existing seat cannot be adjusted freely.
Review the actual stone in consistent face-up images and movement when available. Discuss your visual reference and acceptance criteria before ordering. Avoid treating a generic product photo, a broad cut description or the absence of a comment on the report as a complete appearance guarantee.
Compare length, width, ratio, contour and face-up appearance, together with the agreed grade information. Specify each-stone weight and combined weight clearly. Two ovals can share the same weight and grades yet differ visibly in silhouette when placed next to each other.
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.
09 / Prepare the next conversation
Start with the fixed requirements and explain where the sourcing selection can vary.
Include target outline, length and width constraints, weight preference and the actual document requirement.
