Define the product family
Loose lab-grown diamonds in this collection are polished center-stone sourcing options for engagement rings, pendants and custom jewellery. The ten shape pages describe different outlines and cutting styles, from round brilliant to rectangular step cuts and pointed fancy shapes. A category name is only the beginning: compare the actual dimensions, proportions, report fields and face-up appearance. For an existing setting, its millimeter requirements matter alongside carat weight. Each page helps you state those priorities before requesting a shortlist; none should be read as a promise that every combination is in stock.

Choose with a complete specification
A category page should help you compare options before you submit an enquiry.
Round and fancy brilliant styles create a different visual pattern from emerald or Asscher step cuts. Decide whether the collection needs a circular, elongated, softly squared or pointed outline, then evaluate the actual facet presentation.
Pear, marquise, princess and heart designs require attention to their distinctive tips or corners. Discuss how the final setting protects and accommodates the outline rather than assuming one mount fits every shape.
Use the grading laboratory's actual fields, including any shape-specific cut assessment supplied. Do not apply a round-diamond 3EX label mechanically to all fancy shapes. Confirm weight and dimensions against the proposed stone.
Two attractive individual diamonds are not automatically a suitable earring pair. If the project needs matching, compare outline, face-up size, proportions and color appearance together. Link the separate reports to the pair record.
06 / A practical comparison
Compare the properties that change the purchasing decision, then review the actual selected stones or parcel.
| Shape group | Visual emphasis | Selection check |
|---|---|---|
| Round brilliant | Circular outline and radial facet pattern | Diameter, depth and visual light return |
| Oval, cushion and radiant | Outline proportions and brilliant pattern | Actual dimensions and face-up presentation |
| Emerald and Asscher | Geometric steps and broad visible facets | Step alignment, proportions and visual clarity |
| Pear, marquise and heart | Distinct tips, lobes or a directional outline | Contour symmetry and setting compatibility |
| Princess | Square outline with pointed corners | Corner condition, dimensions and mount fit |
Connect products to the finished piece

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.
Explore the Relevant Product
For a pear pendant, define point direction and how the bail and supporting metal interact with the teardrop outline. Supply length, width, depth and a contour reference before selecting the stone. Review shoulder balance and point support with the mounting plan so the finished pendant preserves the intended silhouette.

08 / Before you source
The collection includes round, oval, cushion, emerald, radiant, princess, pear, marquise, heart and Asscher shape pages. They describe selection requirements and sourcing conversations. Availability in a particular weight, document format or grade must be checked for the proposed order.
No. Two stones of the same weight may have different length, width, depth and outline. Use measured dimensions and a consistent visual reference, particularly when fitting an existing mount or matching stones across a collection.
Individual report requirements belong in the sourcing brief. Confirm the issuing laboratory, actual report coverage and correspondence to each proposed stone. Smaller accent goods and parcels may use a different documentation approach from center stones.
Include the shape, desired weight, millimeter constraints, color and clarity preferences, report requirement and a reference for the outline. If the ring also contains side stones, share that layout so the center and surrounding stones can be considered together.
Submit the specific requirements for review rather than assuming a shape page guarantees all dimensions. State which parameters are fixed and which can vary. This helps compare suitable options without replacing an essential setting constraint with a broad weight range.
09 / Prepare the next conversation
Start with the fixed requirements and explain where the sourcing selection can vary.
Describe the product format, design requirements, document needs and intended purchase unit. The actual selection and commercial terms are confirmed through the quotation.
