Wholesale lab-grown diamonds for Australian jewellery retailers

Search round, oval, emerald, cushion, radiant, pear and other shapes by carat, colour, clarity and price. Where the supplier provides them, compare cut, polish, symmetry, fluorescence, certificate number and grading laboratory. Fancy-shape proportions and actual appearance matter alongside the grading table.

GIA or IGI reports may be available for particular stones. Do not assume that every listing comes with an identical grading report; confirm what is supplied for the exact diamond.

Lab-grown diamonds are diamonds made through laboratory processes rather than geological formation. CVD and HPHT are two diamond growth methods. Where a report or listing states the growth method or includes treatment disclosures, review those details as part of the customer's requested specification.

If an image, video or updated report is important for the finished jewellery brief, ask the team to check that information for the individual stone before ordering.

Australian stock is distinguished from overseas supplier inventory so retailers can plan customer appointments and manufacturing work more confidently. Physical location, stock availability and delivery timing are confirmed before purchase; overseas listings may change without notice.

Approved retailers see AUD pricing in the trade platform. Holds, memo and final orders depend on account permissions, eligible stock and availability confirmation.

For earrings, provide individual or total carat, shape and approximate dimensions so a matched pair can be sourced. For pavé, tennis bracelets and bands, specify millimetre size, colour, clarity and total quantity. Matching details can be especially important in multi-stone work.

Loose diamond supply can also be discussed alongside custom diamond jewellery manufacturing and CAD requirements for the finished design.

Do I need a jewellery trade account?

Yes. Catalogue access is for approved jewellery retailers. Apply with your business details; each order remains subject to confirmation.

Are all lab-grown stones certified?

Not every item has the same documentation. Review the certificate information on the individual listing, or ask the team to check it.

Can I source matching stones or calibrated sizes?

Send the preferred carat or millimetre dimensions, colour, clarity and quantity. The team can check current availability.
