Matched Lab-Grown Diamonds / Business sourcing
Oval, pear and other same-shape loose diamond pairs, selected around outline consistency and your finished-design requirements.
Preferences are a brief, not a live inventory selection.
A product brief, not just a grade list
Fancy-shape matched pair lab-grown diamonds require attention to the contour as well as the individual grading data. Two ovals can share a weight while differing in ratio or shoulder shape; two pears can differ in tip position or rounded-end balance. Identify the shape, dimensions and orientation your design needs before asking for a pair. The reference configuration on this page is two ovals with a 1.44 length-to-width ratio, but other same-shape requests can be discussed individually. Keep the weight and document record of each stone distinct from the combined pair. Actual matching, supply and suitability must be confirmed for the proposed diamonds rather than inferred from a generated product image.
01 / Define the actual requirement
Separate the product description, sample values and information that must be confirmed for the actual selected goods.

| Illustrative pair weight | 1.00 ct each / 2.00 ct total weight; reference only |
| Reference ratio | 1.44 length-to-width for both illustrative ovals |
| Individual dimensions | Length, width and depth recorded for each actual stone |
| Other pair requests | Pear, emerald-cut and other defined same-shape pairs, subject to confirmation |
| Orientation and contour | Agree same-direction or mirror placement and accepted outline differences |
| Matching record | Individual grades and identifiers plus a side-by-side visual reference |
| Growth method | Confirm CVD or HPHT for the proposed goods |
| Documentation | Confirm the available laboratory report or batch documentation |
| Post-growth treatment | Confirm disclosed treatment information for the proposed goods |
| Order unit | A two-stone same-shape pair, with per-stone and total weights identified |
| MOQ / price / lead time | Confirmed only in the quotation for the agreed specification |
| Growth method | Confirm CVD or HPHT for the proposed goods |
|---|---|
| Documentation | Confirm the available laboratory report or batch documentation |
| Post-growth treatment | Confirm disclosed treatment information for the proposed goods |

Provide the complete earring drawing, ratio direction and contour reference.
02 / Choose against the design
Use these product-specific checks to make your quotation request more precise.
A ratio describes length relative to width but does not define shoulders, corners or tips. For an oval pair, compare the complete contour. For other fancy shapes, identify the characteristic details that must work together in the finished design.
A pear earring pair may be intended to face in matching or mirrored directions. Show the arrangement in the design so the two stone positions are understood before the final selection is approved.
Length, width and depth belong to each diamond separately. Record the differences that can be accepted in your mounts, and do not replace that information with one average measurement or a combined carat figure.
Use a consistent view of the two stones together where available. Evaluate outline, apparent color and light return as a pair, then confirm that the proposed documents correspond to the actual stones being considered.
03 / Plan from the finished design
The finished setting or production workflow determines which measurements and matching decisions belong in the enquiry.
APPLICATION 1
Fancy-shape studs can reveal small contour differences because the pieces are viewed as a pair. Share the mount dimensions, preferred outline and intended orientation before comparing proposed stones.
Brief This Application
APPLICATION 2
Review the two ovals in a consistent face-up view. Compare their outlines and dimensions, including the 1.44 reference ratio, while retaining separate records for the actual selected stones. A similar ratio does not replace approval of shoulders, curvature and visual balance.
Brief This ApplicationADDITIONAL DESIGN USE
For a hanging design, the diamond direction and relation to the metal structure matter. Provide a full earring drawing and identify whether the two focal stones should appear parallel or mirrored when worn.
Brief This Application04 / Your buying model
Create a coherent pair whose outline and orientation match the intended wearing view.
Include in the RFQ: Provide the complete earring drawing, ratio direction and contour reference.
Compare two proposed stones together for a client order with clear individual and total weights.
Include in the RFQ: State the shape, desired scale, matching criteria and document expectations.
Connect a paired-stone selection to the dimensions of the mounts and the approved collection look.
Include in the RFQ: Identify fixed seat constraints and the acceptable differences between the stones.
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 | Fancy-shape earring selections | Same-shape contour, individual data and pair total |
| United Kingdom | Bespoke paired jewelry | Orientation drawing and contour-matching approval |
| Australia | Made-to-order earring models | Approved outline, repeat reference and document mapping |
For an online or retail earring program, the stone description should distinguish a same-shape pair from two independently selected diamonds. Include a side-by-side view and the individual dimensions. This is a comparison approach for the buying team, not evidence of a national shape ranking.
A bespoke earring request can include tip direction, outline and the relationship between the stone and the metal. Show both left and right pieces, particularly for pear or other directional shapes. Approve the actual pair against that drawing rather than a generic pair image.
For a made-to-order model, keep the contour and orientation reference with each-stone measurements. A later pair should be assessed against the same model requirements, with any differences made explicit. Confirm the supply and delivery arrangements before assigning a finished-piece date.
06 / A practical comparison
Compare the properties that change the purchasing decision, then review the actual selected stones or parcel.
| Buying point | Fancy-shape matched pair | Round matched pair |
|---|---|---|
| Contour | Shoulders, tips, corners or long-axis outline | Circular face-up outline |
| Dimension record | Length, width and depth per stone | Diameter and depth per stone |
| Proportion comparison | Shape-specific ratio and contour | Round proportions and diameter |
| Orientation | May need same-direction or mirrored placement | Usually less directional at outline level |
| Shared requirement | Side-by-side visual matching and clear individual records | Side-by-side visual matching and clear individual records |
08 / Before you source
No. The ratio describes length relative to width but does not capture the entire outline or light appearance. Compare shoulders, curvature and the actual face-up view of both ovals. Use the ratio as one measurement within a broader agreed matching brief.
Submit the desired same-shape pair with individual dimensions, contour references and the intended orientation. Availability needs checking for the actual requirement. The two-oval reference shown here does not imply that every shape is offered in every weight or size.
That depends on the design and wearing orientation. Show both earring positions in the brief and mark the intended tip or long-axis directions. The supplier and setter should not have to infer mirror placement from an unlabelled image of two loose stones.
Record each diamond’s weight and the combined total separately. If you request 1.00 ct each, the intended evenly weighted pair totals 2.00 ct. Actual selected stones may have different exact weights, so the final records should state the measured values rather than the rounded example.
Request a consistent side-by-side visual reference and confirm the imagery available for the proposed pair. Color appearance, outline and light return should be reviewed together. Separate photos with different lighting make the visual relationship more difficult to assess.
A repeatable model needs a retained contour, dimension limits, orientation and appearance reference, not just a shape name. Agree what can vary before approving the sample and reconfirm each new pair against the model requirements. Continuing supply must be established separately.
09 / Prepare the next conversation
Start with the fixed requirements and explain where the sourcing selection can vary.
Provide the complete earring drawing, ratio direction and contour reference.
