Lab-Grown Melee Diamonds / Business sourcing
Calibrated small round diamonds for pavé, halos and repeat production, specified by size range and parcel requirements.
Preferences are a brief, not a live inventory selection.
A product brief, not just a grade list
Round lab-grown melee diamonds are purchased to work together across a setting, not simply to look impressive one stone at a time. A useful buying brief defines the diameter range, cutting style, color and clarity range, quantity or total weight, and the way the parcel will be checked. For pavé or halo work, a small difference in fit can interrupt the layout; for repeat production, inconsistent batches can create additional sorting work. Start with your setter’s requirements and the actual dimensions of the setting. MEITUO uses those details to coordinate a sourcing discussion, with availability, tolerances and commercial terms confirmed 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 |
|---|---|
| Product form | Loose round melee, supplied against an agreed parcel brief |
| Cutting style | Round full-cut/brilliant; other styles must be specified separately |
| Illustrative size request | 1.50–1.60 mm diameter range; not a stock or tolerance promise |
| Other size requests | Submit exact sieve or diameter ranges needed by your setter |
| Color / clarity | Requested batch ranges, subject to confirmation and inspection basis |
| Quantity / total weight | Specify either stone count, total carats, or both when required |
| Parcel consistency | Agree on size sorting, appearance and acceptance criteria |
| 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 | Parcel, with the agreed count and/or total carat weight |
| MOQ / price / lead time | Confirmed only in the quotation for the agreed specification |
| Cutting style | Round full-cut/brilliant; other styles must be specified separately |
|---|---|
| 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 |

02 / Choose against the design
Use these product-specific checks to make your quotation request more precise.
Provide the actual stone-seat requirement before choosing a nominal diameter. A parcel described only as 1.5 mm leaves the accepted size range unclear. Ask your setter which measurements need controlling and include that information with the quotation request.
A one-carat parcel is a total-weight purchase, not a promise of a fixed stone count. If your design needs exactly forty stones, state that count and ask how the final weight will be recorded.
Color and clarity ranges describe the agreed parcel, while an individual grading report describes a particular stone. Decide which batch records, sampling checks and visual comparisons are needed rather than assuming every tiny diamond carries a separate report.
Keep the approved diameter interval, cutting style and visual reference for the next order. A repeat request should identify the specification and acceptance method; a previous invoice alone does not describe the sorting work your production requires.
03 / Plan from the finished design
The finished setting or production workflow determines which measurements and matching decisions belong in the enquiry.
APPLICATION 1
Pavé shoulders and halos use many small round stones in a close layout. Supply the seat dimensions and design count, then review the parcel’s fit and visual consistency so the accents support the center and follow the intended pattern.
Brief This Application
APPLICATION 2
Before a parcel enters production, compare the agreed size interval and group appearance with the setting requirement. Keep the sorting record attached to the batch so the stone count, total weight and intended design can be reviewed together.
Brief This ApplicationADDITIONAL DESIGN USE
Keep an approved size and appearance reference for repair or replenishment needs. Identify the additional count separately from the current design requirement, and compare any later parcel against the retained specification before using it in an existing piece.
Brief This Application04 / Your buying model
Control fit and visual consistency across multiple settings rather than sorting an undefined mixed bag after delivery.
Include in the RFQ: Send your size intervals, annual or project quantities, acceptance criteria and replenishment schedule.
Obtain a parcel suited to a specific band, halo or repair task without confusing stone count with total weight.
Include in the RFQ: Provide the design count, nominal seat diameter and any reserve stones needed.
Create a repeatable accent specification that can be shared with both the sourcing partner and the setting workshop.
Include in the RFQ: Include reference images, the setting plan and the inspection priority for your collection.
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 | Bridal production and repair parcels | Diameter interval, design count, reserve quantity and documentation |
| United Kingdom | Independent bench and bespoke halo work | Sieve ranges, setting drawing and small-lot replenishment needs |
| Australia | Made-to-order bands and replenishment | Per-design count, approved reference and required date |
For a US-facing bridal program, the practical question is whether the accents suit the actual mount and can be described consistently in your product information. Treat this as a production brief: list the seat sizes and quantities, then compare offered parcel data against the same requirements.
An independent jeweller building a bespoke halo may need only a defined selection of small rounds. Supply the complete layout and ask for the requested range to be confirmed. This is an illustrative purchasing scenario, not a claim about national buying preferences or minimum order terms.
For a made-to-order band collection, retain the approved melee interval and visual reference with the design file. Include destination and the date by which the setter needs the parcel, allowing sourcing and delivery arrangements to be discussed before a production commitment is made.
06 / A practical comparison
Compare the properties that change the purchasing decision, then review the actual selected stones or parcel.
| Buying point | Round melee parcel | Round center stone |
|---|---|---|
| Main task | Supply small accents that work together | Select an individual focal diamond |
| Primary dimensions | Agreed diameter interval or sieve range | Individual diameter, depth and proportions |
| Quantity basis | Parcel count and/or total carat weight | Weight per stone |
| Evidence | Agreed batch inspection and documents | Individual stone data and report when supplied |
| Repeat request | Retain parcel sorting and appearance criteria | Retain the approved individual specification |
08 / Before you source
Give the accepted millimeter interval, cutting style, requested color and clarity range, and quantity or total carat weight. Add your setting requirement and inspection expectations. A nominal size alone does not tell the sourcing team how tightly the parcel needs to be sorted.
No fixed count should be assumed from total weight alone. The number depends on the stones supplied and their actual weights. If your design needs a particular count, request that count explicitly and agree how both count and total weight will appear in the packing record.
Do not assume individual reports for every small diamond. Confirm the documentation offered for the requested parcel and the identity or quality checks you need. Where individual reports are required, discuss the practical availability and cost implications before treating them as part of the order specification.
Yes, state the required cutting style in the sourcing brief. Full-cut and single-cut are different facet arrangements, so the words should not be used interchangeably. Match the style to the visual effect and setting requirements agreed with your production team.
The accepted interval must be agreed for your specific request. The illustrative size range on this page is not a universal manufacturing tolerance. Your setter’s seat dimensions, the available sorting method and the inspection criteria should inform the final acceptance range.
Refer to the approved specification rather than only the previous order number. Keep the diameter interval, cutting style, color and clarity range, appearance reference and quantity basis. Reconfirm availability and commercial terms for each replenishment, especially where a new supply batch is proposed.
09 / Prepare the next conversation
