Matched Lab-Grown Diamonds / Business sourcing
Two round loose diamonds reviewed together for earring programs, custom pairs and clearly defined repeat orders.
Preferences are a brief, not a live inventory selection.
A product brief, not just a grade list
Round matched pair lab-grown diamonds are selected as a visual partnership, not simply as two stones with similar labels. A buyer needs to compare diameter, proportions, face-up appearance and the color relationship between the two, alongside any individual reports. The quotation should make the weight of each stone and the combined pair weight unmistakable. For earrings, the mount and viewing context also belong in the discussion. MEITUO uses a pair-specific brief to coordinate the selection and document requirements, with the actual two stones, matching criteria and commercial conditions confirmed before an order. The example here illustrates the product format rather than an available reserved pair.
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 |
|---|---|
| Product form | Exactly two round brilliant loose diamonds, selected as one visual pair |
| Illustrative pair weight | 0.50 ct each / 1.00 ct total weight; sample configuration only |
| Dimensions | Record diameter and depth separately for both stones |
| Proportions | Compare the actual table, depth and face-up appearance where data is supplied |
| Color / clarity | Individual report data and visual pair relationship, as applicable |
| Matching criteria | Agree dimensional difference, appearance and inspection conditions |
| Report correspondence | Keep each report or stone identifier attached to the correct diamond |
| 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 | One matched pair; per-stone weights and pair total stated separately |
| MOQ / price / lead time | Confirmed only in the quotation for the agreed specification |
| Report correspondence | Keep each report or stone identifier attached to the correct diamond |
|---|---|
| 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 |

State each-stone weight, total weight, mount size and matching priorities.
02 / Choose against the design
Use these product-specific checks to make your quotation request more precise.
State the desired weight per diamond and the combined pair total. One carat total weight is not one carat each. This simple distinction keeps the comparison aligned with the earring size and purchasing budget you actually intend.
Two rounds of similar weight can have different face-up dimensions. Review the actual diameters and proportions against the mounts, then agree what difference can be accepted in the finished earring pair.
Matching is a relationship between two diamonds. Ask for a consistent side-by-side visual reference where available, and evaluate their color appearance and light return together rather than approving two unrelated photographs under different lighting.
A pair is one purchasing unit but still contains two distinct stones. Keep individual report details, dimensions and weights linked to the correct diamond so the evidence and the goods remain aligned through setting and future records.
03 / Plan from the finished design
The finished setting or production workflow determines which measurements and matching decisions belong in the enquiry.
APPLICATION 1
Round studs require a balanced face-up diameter and an agreed visual relationship. Share the intended settings and specify each-stone weight as well as the total so the proposed pair reflects the desired finished size.
Brief This Application
APPLICATION 2
Review both rounds together rather than comparing separately lit photos. Relate the actual diameters and face-up appearance to the intended mounts, and keep individual stone records within one pair approval so weights and documents remain unambiguous.
Brief This ApplicationADDITIONAL DESIGN USE
A design may place two round diamonds in different parts of the same piece while still requiring visual balance. Explain the positions, dimensions and intended relationship rather than assuming a generic earring pair is automatically suitable.
Brief This Application04 / Your buying model
Compare a coherent pair for a client order rather than two separate stones with approximate combined weight.
Include in the RFQ: State each-stone weight, total weight, mount size and matching priorities.
Maintain an approved visual standard while discussing new selections for repeated models.
Include in the RFQ: Retain diameter criteria, appearance reference and per-stone record requirements.
Confirm that both stones fit their mounts and that the pair makes sense in the finished setting.
Include in the RFQ: Provide the seat dimensions and the accepted visual and dimensional differences.
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 | Stud earring assortment briefs | Each weight, total weight, mount size and pair imagery |
| United Kingdom | Client-led earring commissions | Desired finished scale and paired-appearance review |
| Australia | Made-to-order studs and replenishment | Approved sample record, document mapping and required date |
For a US-facing stud assortment, make the product-size description and stone request use the same weight language. A pair total alone leaves individual sizes unclear. Ask for actual diameters and suitable visual evidence before selecting the two stones for a particular model.
A jeweller arranging a commissioned pair can start from the intended finished earring size and the preferred mount. Identify which visual differences are acceptable and how the pair will be approved. This describes one possible procurement process, not a national purchasing preference.
For a made-to-order stud model, store the matching brief with the model rather than relying solely on a carat label. A new pair should be reviewed against that reference. Confirm sourcing and delivery arrangements for the actual order before assigning a completion date.
06 / A practical comparison
Compare the properties that change the purchasing decision, then review the actual selected stones or parcel.
| Buying point | Matched round pair brief | Two separate single-stone briefs |
|---|---|---|
| Approval focus | The two stones’ relationship | Each stone evaluated independently |
| Dimensions | Both diameters and their accepted difference | One stone’s dimensions at a time |
| Appearance | Consistent side-by-side review | Separate visual references may differ |
| Weight language | Each stone plus combined total | Individual weight only unless combined later |
| Records | One pair record with two stone identities | Separate records requiring later coordination |
08 / Before you source
It describes the combined weight of the two diamonds, not the weight of each one. An illustrative evenly weighted pair could be 0.50 ct each, adding to 1.00 ct total. The actual quotation should state both individual weights and the combined total.
Agree the matching criteria for the project rather than assuming one universal rule. Individual grades matter, but dimensions, proportions and face-up appearance also affect the finished pair. A pair with similar labels still needs to be assessed together in the intended viewing context.
Confirm the document requirement and availability for each proposed diamond. Where individual reports are supplied, preserve the correspondence between each stone and its record. A matched-pair label does not create a combined laboratory report or establish the documentation automatically.
Provide the diameter and depth constraints of both mounts and ask your setter to identify any permitted variation. The sourcing discussion can then compare proposed stones with the actual settings. Carat weight alone does not confirm that both diamonds will fit.
Include a consistent side-by-side visual review in the brief and confirm what imagery or video is available for the proposal. Compare the pair under similar conditions rather than relying on independently lit images that make color or brilliance difficult to judge.
Keep the approved diameter range, proportion priorities, appearance reference and document requirements with the model. Reconfirm the actual stones and their matching for each new pair. A successful earlier order is a useful reference, not a guarantee of identical future stock.
09 / Prepare the next conversation
Start with the fixed requirements and explain where the sourcing selection can vary.
State each-stone weight, total weight, mount size and matching priorities.
