Loose Lab-Grown Diamonds / Business sourcing
Select emerald-cut lab-grown diamonds through step-facet appearance, clipped-corner outline and setting dimensions, with documentation reviewed stone by stone.
Preferences are a brief, not a live inventory selection.
A product brief, not just a grade list
Emerald cut lab-grown diamonds bring a rectangular step-cut structure to a sourcing brief. The name describes a diamond cutting style here, not a green emerald gemstone. Long parallel facets and an open face-up pattern make visual review especially useful when comparing proposed stones. Record the required length, width, depth, clipped-corner outline and preferred proportion, then consider the actual report information alongside images and movement. For three-stone designs, the side-stone layout and relative scale should be discussed at the same time. MEITUO organizes sourcing around that complete design requirement; sample dimensions on the page are illustrative and do not represent a live certified inventory item.
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 | Rectangular step cut with clipped corners |
| 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 | 9.00 × 6.40 × 4.30 mm (L × W × D); not measurements of an offered stone. |
| Proportion / outline | 1.41 in the illustrative configuration; length-to-width preference is set by the design brief. |
| 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 | Rectangular step cut with clipped corners |

Provide length, width, depth, ratio reference, corner geometry and the mount’s fixed constraints.
02 / Choose against the design
Use these product-specific checks to make your quotation request more precise.
Look at how the broad parallel reflections behave as the proposed stone moves. Assess its face-up appearance against your own reference instead of assuming that one set of report grades describes every visible effect. Use consistent lighting when comparing shortlisted stones.
The clipped corners form part of the actual outline and may differ between diamonds with similar length and width. Include the corner geometry and mount clearance where they are constrained. A rectangular bounding box alone is not a complete setting-fit specification.
Use the actual grading information with face-up imagery, rather than imposing one universal clarity threshold on all step cuts. If a visible feature would be unacceptable in a particular mount, define that acceptance criterion before deciding which proposed stones to approve.
For a three-stone design, communicate the center’s outline and dimensions together with side-stone shape, orientation and relative scale. Center and sides may need different documents and matching criteria. A complete layout brief reduces ambiguity before either part is selected.
03 / Plan from the finished design
The finished setting or production workflow determines which measurements and matching decisions belong in the enquiry.
APPLICATION 1
Coordinate the rectangular emerald-cut center with the baguette side stones through a complete ring layout. State the center’s dimensions, side-stone dimensions, orientation and relative scale before selection. Review the proposed combination together, and identify the center and each side separately in the quote with their applicable document and matching requirements.
Brief This Application
APPLICATION 2
Emerald-cut stud earrings need two rectangular step-cut stones that read together in outline and appearance. Specify each-stone and combined weights, length, width, ratio and corner treatment. Review the pair in the same orientation, including how the broad reflections compare, rather than treating two similar grading summaries as a complete matching assessment.
Brief This ApplicationADDITIONAL DESIGN USE
For a pendant, define whether the rectangle sits vertically or horizontally and how much metal surrounds the clipped corners. A repeated collection needs a dimensional and appearance brief that can be retained for subsequent requests. Approve the individual goods rather than assuming that all emerald cuts share one outline.
Brief This Application04 / Your buying model
Source a step-cut center around a precise architectural design.
Include in the RFQ: Provide length, width, depth, ratio reference, corner geometry and the mount’s fixed constraints.
Coordinate the emerald center with a suitable side-stone layout.
Include in the RFQ: Send the complete drawing, relative scale, side shape, orientation and separate matching or document requirements.
Repeat a step-cut design with a controlled appearance brief.
Include in the RFQ: Retain contour, dimension bands, approved visual reference and order identification for future selection.
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 | Step-cut bridal and three-stone assortments | Center data and side-stone layout |
| United Kingdom | Architectural bespoke commissions | Clipped-corner geometry and setter approval |
| Australia | Made-to-order step-cut jewellery | Orientation, visual reference and approval timing |
A bridal business can request the emerald center and side-stone sourcing as related but separately identified items. Compare the center’s actual dimensions and report while keeping the layout visible. This is a potential purchasing workflow in the market, not proof of a national preference for step-cut rings.
For a commission developed around a restrained rectangular setting, the mount drawing should describe corner support and visible height as well as length and width. Ask the setter to review the selected diamond. The scenario helps define an RFQ; it is not a claim about every British jeweller’s practice.
A studio creating a pendant or ring can specify vertical or east-west orientation in the same brief as the preferred outline. Clarify the approval point before mount completion and whether the design will be repeated. Quoted lead time and supply scope remain specific to the available selection, not a country-wide promise.
06 / A practical comparison
Compare the properties that change the purchasing decision, then review the actual selected stones or parcel.
| Buying consideration | Emerald cut | Asscher-style square step cut |
|---|---|---|
| Outline | Usually an elongated clipped-corner rectangle. | Near-square clipped-corner outline. |
| Facet architecture | Rectangular parallel steps around an open table. | Square-oriented concentric step structure. |
| Proportion brief | Length-to-width ratio affects the rectangle. | Square balance and corner proportions are central. |
| Visual review | Review broad reflections, face-up features and outline. | Review broad reflections, square symmetry and corner balance. |
| Mount specification | Length, width, depth and clipped corners. | Both edge dimensions, depth and clipped corners. |
| Naming boundary | Emerald cut describes a diamond cutting style here. | Generic shape request; no branded patented cut is implied. |
08 / Before you source
No. This page concerns laboratory-grown diamond with an emerald-cut facet arrangement and outline. The material should be identified separately from the cutting style on the quotation and supporting documents. A green emerald gemstone would be a different material and a different product request.
There is no single grade that should be imposed without reviewing the proposed stone and the design. Consider the actual report with face-up images and agree what is acceptable for the finished piece. Broad step reflections make visual assessment useful, but grade labels do not replace individual review.
Send a complete layout including center dimensions, side shapes, orientation and relative scale. State which measurements are fixed and how matching should be judged. Identify the center and each side stone in the quote, with document requirements appropriate to the actual items.
State the horizontal orientation and supply the mount dimensions or drawing. The sourcing task still needs length, width, depth, clipped-corner geometry and an appearance reference. Confirm fit with the setter before approval; changing orientation does not by itself establish that an existing head will fit.
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
