Wholesale natural diamonds for Australian jewellers

Begin with shape, carat, colour and clarity. For round brilliant stones, cut and proportions can be important; for fancy shapes, consider length-to-width ratio, outline and how the diamond will look in the chosen setting. Retailers can also review polish, symmetry, fluorescence and certificate information where supplied.

GIA or IGI report details may be available for individual stones. Not every listing has the same certification, so confirm the certificate number and grading laboratory for the exact diamond being quoted.

Locally held Australian diamonds are shown separately from supplier listings overseas. Location is important when planning a customer appointment or manufacturing deadline. Ask the team to confirm that a specific diamond remains available and to check fulfilment arrangements before committing to the customer.

Supplier listings can change. A search result, a hold request or an enquiry does not guarantee allocation. Memo is considered for approved retailers and eligible stock under agreed terms.

For a centre stone, provide your target carat range and shape as well as any grading or ratio preferences. For earring pairs, matching dimensions and visual appearance matter alongside combined weight. For bands and pavé, specify millimetre size, quantity and quality for smaller natural diamonds.

Fancy-colour diamonds, unusual shapes and exact certificate requests can be sent as enquiries. The availability of a matching natural stone or lot is confirmed by the sourcing team.

Apply for a retailer account and provide your jewellery business details. After approval, search the trade catalogue or submit a diamond brief. Review the specifications and AUD quote, then request a hold or order once the team has confirmed availability.

8CARATS supplies the jewellery trade, not direct-to-consumer buyers. We work from Melbourne with approved retailers around Australia; online supply does not imply a showroom in each city.

Can I request a particular fancy shape or coloured diamond?

Yes. Send the shape, dimensions, colour, carat, clarity, grading requirements and timeframe. The team can check the currently available options.

Can natural diamonds be allocated on memo?

Memo arrangements are subject to retailer approval, stock eligibility and agreed return conditions; they are not automatic for every stone.

How is the final availability confirmed?

8CARATS checks the actual stone with the holder or supplier before the order and invoice are confirmed.
