Wholesale diamonds across Melbourne, Sydney and Australia

8carats is Melbourne-based and supports approved jewellery retailers across greater Melbourne and regional Victoria. Retailers can source natural diamonds, lab-grown diamonds, Australian stock and live global inventory through one B2B account.

Jewellery retailers in Sydney and across New South Wales can use 8carats for loose diamond sourcing and trade jewellery manufacturing without needing a physical 8carats showroom in Sydney.

Approved Queensland retailers can search Australian and global diamond inventory, make enquiries, place holds and follow orders from the same 8carats retailer workspace.

8carats supports trade diamond sourcing for approved jewellery businesses in Perth and across Western Australia, including natural and lab-grown stones and custom jewellery requirements.

Retailer access is available nationally. 8carats also serves approved jewellery businesses across South Australia, the ACT, Tasmania and the Northern Territory through the same B2B sourcing workflow.

Location pages describe where 8carats serves approved retailers; they do not imply a physical store or showroom in every listed city or suburb. Availability, pricing and delivery timing are confirmed for the relevant diamond or jewellery order.
