Loose Lab-Grown Diamonds / Business sourcing
Specify round brilliant center stones and matching pairs by diameter, report details and face-up appearance for your next jewellery order.
Preferences are a brief, not a live inventory selection.
A product brief, not just a grade list
Round brilliant lab-grown diamonds give a jeweller a circular center-stone option that can be compared through diameter as well as carat weight. For a solitaire program, the stone must fit the selected head; for earrings, two apparently similar report labels still need a visual and dimensional match. A useful wholesale brief therefore records minimum and maximum diameter, depth, the actual grading document and the intended supply format. Ask for images under consistent lighting rather than treating a marketing cut description as proof of appearance. MEITUO's sourcing discussion starts with that brief and confirms suitable goods, supporting information and commercial terms for the individual order.
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 | Round 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 | 8.10 × 8.07 × 4.96 mm (L × W × D); not measurements of an offered stone. |
| Proportion / outline | Roundness check: compare minimum and maximum diameter; do not apply an elongated-shape target ratio. |
| 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. |
| Shape / cutting style | Round brilliant |
|---|---|
| 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. |

Send the mount diameter, depth clearance, weight preference and report requirement; distinguish a replacement stone from a new setting project.
02 / Choose against the design
Use these product-specific checks to make your quotation request more precise.
Start with the mount or design drawing. Record the allowed diameter and depth, not only a desired carat weight. A heavier round stone is not automatically the right fit for an existing head or an established earring model.
Review the cut information actually supplied by the issuing laboratory. Terms such as ideal, super ideal or hearts and arrows need their own supporting evidence; they should not be treated as interchangeable grades across different sellers or report formats.
Compare face-up views and movement under similar lighting. Strong reflections, a dark camera silhouette or studio processing can change what a photograph appears to show. Ask what visual material can be provided for the proposed stone, not only the product category.
For round studs, compare the diameters, total depth, overall appearance and agreed color range together. State each-stone weight and combined weight separately. Two stones of equal weight can still look unequal when placed next to each other.
03 / Plan from the finished design
The finished setting or production workflow determines which measurements and matching decisions belong in the enquiry.
APPLICATION 1
A circular center works with a range of solitaire concepts, but the sourcing task remains specific: match diameter, height clearance and visual standard to the actual ring head. Include a drawing or existing mount dimensions before comparing proposed stones, especially when replacing a center stone in a retained setting.
Brief This Application
APPLICATION 2
A matched stud program requires two stones rather than two isolated purchases. Describe the preferred individual weights, total pair weight and acceptable dimensional difference. Review both stones in the same view so the choice addresses the finished pair instead of relying only on separate grading summaries.
Brief This ApplicationADDITIONAL DESIGN USE
For a repeat pendant design, retain the approved diameter range and setting reference with the buying record. Future sourcing can then be discussed against an established design specification. The aim is consistent fit and appearance across the collection; exact availability still needs confirmation for each order.
Brief This Application04 / Your buying model
Replace or select a circular center for a client design without guessing from carat weight.
Include in the RFQ: Send the mount diameter, depth clearance, weight preference and report requirement; distinguish a replacement stone from a new setting project.
Build round stud pairs with a consistent visual standard.
Include in the RFQ: List per-stone and pair weights, diameter tolerance, metal and mounting reference, and whether repeated pair selection is expected.
Compare round selections across a defined business order.
Include in the RFQ: Group the request by diameter or weight band, document requirements and order unit; keep every approved stone or pair identifiable in the selection list.
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 | Round bridal and stud assortment | Diameter, report fields and pair-weight terminology |
| United Kingdom | Independent-jeweller replacement and bespoke work | Existing head dimensions and individual documentation |
| Australia | Made-to-order solitaire and pendant collections | Design approval sequence and repeat diameter bands |
A bridal retailer developing a round solitaire and stud assortment can ask for separate center-stone and matched-pair shortlists. Keep the categories distinct in the RFQ: one stone for a ring, two stones for earrings. This is a procurement scenario for the market, not a claim about national market share or a specific retailer’s orders.
A workshop sourcing for a client-owned mount should put millimeter fit ahead of a broad weight request. Ask which measurements and visual references will accompany the selection, and have the setter review the actual stone. The example illustrates one buying use case rather than a general preference attributed to all British buyers.
A made-to-order business can retain a round setting specification and use it when briefing the next sourcing request. Include approval timing and destination alongside the stone requirements. Any quotation or delivery date remains specific to the proposed goods; this scenario is not a verified measure of Australian demand.
06 / A practical comparison
Compare the properties that change the purchasing decision, then review the actual selected stones or parcel.
| Buying consideration | Round brilliant | Oval brilliant |
|---|---|---|
| Outline | Circular; compare minimum and maximum diameter. | Elongated; compare length, width and ratio. |
| Setting brief | Diameter, depth and head dimensions. | Length, width, depth and contour of the mount. |
| Visual review | Review radial symmetry, proportions and light return. | Review outline symmetry, bow-tie appearance and light return. |
| Earring pair selection | Match diameter and face-up appearance together. | Match length, width, ratio and face-up appearance together. |
| Commercial comparison | Price and availability depend on the proposed stones. | Price and availability depend on the proposed stones. |
| Design decision | Choose the circle that fits the piece. | Choose the elongated outline that fits the piece. |
08 / Before you source
Include minimum and maximum diameter, depth, intended setting, report requirements and quantity. For a pair, state each-stone weight and combined weight separately. These details make comparisons useful and help identify whether proposed goods fit the finished design rather than only the budget band.
No such claim should be assumed from the round shape alone. If the optical pattern matters to your buying plan, request the relevant supporting images and agree how it will be assessed. A generic product photograph or the word brilliant is not evidence for that specific claim.
Yes. Face-up dimensions and proportions need to be compared separately from mass. Record the actual diameter range and depth when reviewing a shortlist. If the stone must fit an existing mounting, the setter’s dimensional requirements should be part of the acceptance criteria.
Specify the desired weight of each stone, total pair weight, diameter range and matching criteria. Ask to review the stones together when visual material is available. A label such as one carat studs is ambiguous unless the quotation states whether that weight is per stone or per pair.
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.
Send the mount diameter, depth clearance, weight preference and report requirement; distinguish a replacement stone from a new setting project.
