GIA Certified Diamonds

The Diamond Jewellery Studio has a wealth of experience in crafting beautiful pieces of diamond jewellery.

For us, it’s important to select genuine, high-quality diamonds that have been sourced from responsible sites. We maintain this commitment by only partnering with sources we trust, and supplying each of our diamonds with GIA Certification.

GIA Certification verifies the 4Cs of each diamond – the Cut, Colour, Clarity and Carat weight. We provide certification so you can be sure that the wholesale diamonds you purchase are genuine articles.

One of the most important factors in the value of diamonds is the cut. Our partners can source diamonds in every cut imaginable. From traditional shapes like emerald or diamond cuts, through to complex examples like TripleEx H&A™ diamonds.

Whether you are investing in the future, expanding your collection or purchasing wholesale diamonds for your next jewellery piece, we can find the perfect gemstone for your budget.

The Diamond Jewellery Studio offers Melbourne’s biggest range of wholesale diamonds. With sources all over the world, we’re able to supply diamonds in any cut, grade, colour or size you need.

In addition to our range of White Diamonds, we can source a broad selection of Australian Pink Diamonds, as well as exotic colours like blue, champagne and yellow.

Coloured diamonds are some of our favourite gemstones to work with. They make our pieces stand out, and the rarity of high-quality coloured diamonds makes them an excellent choice for investors.

Because coloured diamonds are so in-demand, it’s important to verify that your stones have come from a reliable source. We take care of this process on your behalf, giving you peace of mind that your diamonds are responsibly sourced and conflict-free.

If you want a flawless white diamond, rare pink diamonds from the Argyle Mine, or any other type of coloured diamond, our team can source the perfect gemstone.

Don’t Just take our word



The Diamond Jewellery Studio offers a range of wholesale diamonds in Melbourne, including a number of affordable options.

We are accredited members of the Gemmological Association of Australia (GAA), the Diamond Dealers Club of Australia (DDCA), the Canadian Diamond Code of Conduct Committee (CDCC), and also the World Federation of Diamond Bourses (WFDB). This has helped establish our team as a reputable dealer of diamonds in Melbourne.

Diamonds are generally a good investment. The value has remained high over long periods of time, and the rarity of jewellery-grade diamonds means they are always in demand.

If you’re purchasing loose diamonds as an investment, our team can help select the diamonds Melbroune investors value the most.

High-quality diamonds are the best option for investors. Flawless diamonds are valued more highly and hold their value better over time. Regardless of the size of the diamond, the clarity, colour and quality of stone will determine its long-term value.

Coloured diamonds can also make an excellent investment. Gemstones like pink diamonds from the Argyle Mine are very rare, and they tend to increase in value over time.

When you shop for wholesale diamonds in Melbourne, it’s important to buy from experts who can give you high-quality gems that hold their value. Buying from a specialist also makes it easier to find rare coloured gems and unusual cuts, which can make your collection even more valuable.
