Where can I buy loose, wholesale diamonds?

At GS Diamonds, we offer premium diamonds for sale across Australia, both online and in our showrooms. You can buy loose diamonds or just explore our extensive collection, graded by experts who evaluate them by the 4Cs standard (colour, clarity, cut and carat weight). And yes, we get that buying diamonds online can feel counterintuitive. That’s why our trusted experts are here to guide you every step of the way. If you’re after the best place to buy diamonds in Australia, where ordering online can be stress-free, you’re in the right place!

Where to buy ethical diamonds online?

If you are wondering where to buy conflict free and ethically sourced diamonds, GS Diamonds is the most trusted choice. We provide certified natural diamonds, as well as sustainable lab-grown diamonds. Both options let you shop ethically, with no compromise on beauty or quality.

What does carat size mean?

Diamond carat does not mean size, not exactly. Carat measures weight, not physical dimensions. To understand proportions and how to tell the carat size of a diamond, see our full guide to diamond carat size

What is the price of diamond per carat?

Diamond prices vary by the 4Cs: cut, colour, clarity, and carat. The diamond price in Australia also depends on certification and market demand. If you’re wondering how much a diamond’s worth is, our specialists can help you explore current pricing.

Do your diamonds come with a diamonds grade report?

Yes, all our loose diamonds that you see on our online inventory come with a GIA Grading certificate which is the most trusted grading report in the world and most diamonds are laser inscribed on the girdle with their identification number for your peace of mind.
