Wholesale Diamonds Sydney

Diamond Imports is one of Australia's most established diamond wholesalers, operating from Sydney's CBD since 1980. We import natural certified diamonds — bought directly from the world's major diamond bourses — and sell them to private buyers, couples, and the jewellery trade across Australia.

We are Sydney-based, but our customers are everywhere. Buyers in Melbourne, Brisbane, Perth, Adelaide, Canberra, Darwin, and regional Australia buy wholesale diamonds from Diamond Imports regularly — by phone, online, and with fully insured delivery direct to their door.

What Makes Diamond Imports a True Wholesale Diamond Supplier?

The word “wholesale” is used loosely in the diamond industry. Many retailers describe themselves as wholesalers while operating exactly like a traditional jewellery shop — with retail margins, commission-based staff, and no direct access to the source.

Diamond Imports is different in four specific ways:

• We source independently. Every diamond we sell is hand-selected by us — we do not simply list diamonds from external databases or rely on other dealers to choose stones on our behalf.
• We buy direct from the source. We purchase diamonds directly from the major international diamond bourses — the primary wholesale markets where diamonds are traded globally. This eliminates one or more layers of margin between the mine and the buyer.
• No commissions, ever. When you speak with us, you speak with the owner. There are no sales staff on commission. Every recommendation is made in your interest.
• Below retail pricing. Because we operate as an importer and wholesaler — not a traditional retailer — our pricing sits meaningfully below what you would pay at a retail jewellery store for an equivalent certified diamond.

We work with you directly, present stones matched to your requirements, and guide you through to a decision you feel completely confident in.

• Sydney — by appointment at our CBD office. View diamonds in person, compare stones side by side, and decide with your eyes.
