Lab Diamond Sourcing

Oval Lab-Grown Diamonds for Wholesale Jewelry Buyers

Oval stones need a more visual sourcing brief than a simple carat and grading range. Outline, length-to-width ratio and the appearance of the bow-tie area can materially change how a stone works in a bridal or branded design.

Define the outline your design needs

An oval laboratory-grown diamond can appear elongated, balanced or broad even at a similar weight. Share a preferred length-to-width range or, better, the actual minimum and maximum dimensions that suit the setting. The outline should also be reviewed for shoulder shape and symmetry because these details influence the visual result and prong placement. If the design is based on an existing CAD or mounting, provide the center-stone seat information after first contact so unsuitable options can be removed early.

Use media to review the bow-tie area

The bow-tie effect is not fully described by a color or clarity grade. Request face-up video or comparable visual material when available and assess the dark or contrasting area across the center in the lighting provided. Media conditions vary, so the review should be treated as a sourcing aid rather than a guarantee that a stone looks identical in every environment. The final record should still connect the video, report information, dimensions and physical stone. A buyer can state the level of visible bow-tie that is acceptable for the intended price position and design.

Matching ovals requires clear tolerances

For earrings and side-stone pairs, match length, width, length-to-width relationship, outline, color, clarity and face-up appearance. Weight alone is not enough. If the ovals will sit on opposite sides of a center stone, include orientation and setting constraints. For a branded repeat style, document the acceptable range for each characteristic so later replenishment can be checked consistently. Availability, pricing and lead time remain quotation-specific because suitable visual matches may require comparison across more than one supply source.

Oval sourcing questions

Can you guarantee no bow-tie in an oval?

No absolute visual guarantee is made from a text specification. State your tolerance and review available face-up media for each proposed stone.

What should be matched in oval earrings?

Length, width, ratio, outline, color, clarity, weight relationship and face-up appearance should be reviewed together.

Can I request a specific oval ratio?

Yes. Provide a target range and any mounting dimensions. Current options are checked against that brief.
