Loose Lab-Grown Diamonds / Business sourcing
Source princess-cut lab-grown diamonds with clear edge dimensions, corner-support requirements and matched-pair criteria for rings, studs and repeat designs.
Preferences are a brief, not a live inventory selection.
A product brief, not just a grade list
Princess cut lab-grown diamonds place a square modified-brilliant request into a business sourcing plan. The sharp corners and straight-edge outline need to be considered with the mounting, not treated as a decorative detail after a stone is chosen. For studs, compare both edge dimensions, overall appearance and the required pair weight. For a ring head, include how the corners will be supported and any depth clearance supplied by the setter. MEITUO works from that brief to coordinate proposed selections and agreed quality requirements. The example dimensions are illustrative; exact weight, cutting description, grades, document coverage and commercial terms must be confirmed for the selected goods.
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 | Square modified brilliant; actual report cutting description applies |
| 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 | 7.00 × 6.95 × 4.90 mm (L × W × D); not measurements of an offered stone. |
| Proportion / outline | 1.01 in the illustrative near-square configuration; edge equality and corner geometry need individual review. |
| Color & clarity | Request your preferred range; final individual grades are as reported. |
| Mounting review | Point/corner support, orientation and clearance should be approved by the setter for the actual stone. |
| 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. |

Provide edge dimensions, depth limits, mounting reference and required document coverage.
02 / Choose against the design
Use these product-specific checks to make your quotation request more precise.
Check the actual corner condition and discuss protective support with the setter. Include the intended mounting design in the request rather than approving the stone from a face-up image alone. The quotation and acceptance record should identify the actual goods being reviewed.
Near-square does not mean every stone has exactly equal sides. Record the individual length and width and compare them against the seat or stud design. A weight band cannot replace this check, especially where a repeated model has limited adjustment room.
Include depth or pavilion-clearance constraints when sourcing for an existing head. The visible square outline is only part of the fit requirement. Confirm the selected stone with the setter before assuming that a face-up dimensional match is sufficient.
A pair should be checked for edge dimensions, outline, apparent color and face-up pattern. State how the stones will be oriented and the weight of each. Two separate princess selections do not automatically form a visually coordinated pair for earrings.
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 princess center needs a head that supports its corner geometry and accommodates its depth. Supply the setting reference and any fixed dimensions with the brief. Review the actual stone’s condition, report and appearance before accepting it for a new ring or an existing client mount.
Brief This Application
APPLICATION 2
A princess-cut tennis bracelet requires a sequence of square stones suited to repeated settings, not an isolated center-stone specification. Brief the required edge dimensions, depth clearance, quantity and matching criteria for the full layout. Confirm suitable calibrated sizes separately; the illustrative center-stone dimensions on this page do not define the bracelet’s stones.
Brief This ApplicationADDITIONAL DESIGN USE
When a princess center is combined with other geometric stones, coordinate the center outline and mounting layout early. A design drawing helps distinguish fixed spacing from adjustable setting elements. Keep dimensions and corner-support requirements with the approved stone list for later production discussions.
Brief This Application04 / Your buying model
Select a square center that works with a suitable corner-supporting head.
Include in the RFQ: Provide edge dimensions, depth limits, mounting reference and required document coverage.
Develop princess pairs with balanced square outlines.
Include in the RFQ: State individual and total weights, both edge measurements and acceptable appearance differences between stones.
Source square modified-brilliant stones for a retained design specification.
Include in the RFQ: Supply layout drawings, orientation, corner-support notes, quantity and dimensional acceptance criteria.
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 | Square solitaire and stud assortments | Head compatibility and pair-weight clarity |
| United Kingdom | Client-specific square center selection | Corner support and setter review |
| Australia | Repeat square stud and ring models | Dimensional records and approval timing |
A retailer building a square-stone assortment can separate single ring centers from earring pairs at the RFQ stage. Include mounting requirements and both edge dimensions for each model. This is a potential buying structure, not evidence that princess cuts hold a particular position in American demand.
For a bespoke or replacement project, the jeweller can place corner support and depth clearance alongside the visual reference. The setter should review the actual selected stone. This scenario supports precise sourcing communication rather than attributing a universal technical policy or style preference to British buyers.
A small collection can retain separate specifications for a princess stud pair and a ring center, even where the grade range is similar. Confirm selection timing before mount production and include destination. Supply and delivery terms require quotation; no national sales trend is asserted by this example.
06 / A practical comparison
Compare the properties that change the purchasing decision, then review the actual selected stones or parcel.
| Buying consideration | Princess cut | Cushion cut |
|---|---|---|
| Outline | Near-square with pointed corners and straight edges. | Square or elongated with rounded corners and curved sides. |
| Facet description | Commonly square modified brilliant; actual report applies. | Brilliant or modified brilliant; actual report applies. |
| Mount consideration | Corner support and depth clearance require attention. | Contour and corner curvature require attention. |
| Pair matching | Compare both edge dimensions and square outline. | Compare contour, ratio and face-up pattern. |
| Substitution risk | A rounded-corner cushion is not the same fit. | A sharp-corner princess is not the same fit. |
| Buying basis | Selected stone, report and setting requirements. | Selected stone, report and setting requirements. |
08 / Before you source
A princess request generally describes a square modified-brilliant stone with pointed corners. A radiant has clipped corners and may be square or rectangular. Confirm the report description and actual outline, because a similar face-up size does not make the two stones interchangeable in a fitted mount.
Ask to review the actual corner condition and discuss support with the setter. Provide the mounting reference and agree the acceptance criteria for the selected stone. Neither a broad grade label nor a generic catalogue photograph should replace an assessment of the goods being proposed.
The required weight relationship should be stated, but matching also involves edge dimensions, outline and face-up appearance. Specify weight per stone and combined pair weight, then review the stones as a pair. Equal weight alone cannot establish how balanced the finished earrings will look.
Check the actual seat, corner geometry and depth clearance rather than relying on the word square. Send measurements or a drawing and have the setter assess the selected diamond. Different square-outline cutting styles may need different support and should not be treated as automatic substitutes.
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.
Provide edge dimensions, depth limits, mounting reference and required document coverage.
