While diamonds are a global commodity, India generally offers the cheapest prices due to its massive cutting/polishing industry (especially in Surat) and lower labor costs, followed closely by Dubai (UAE) for tax advantages and major trading hubs like Antwerp (Belgium), where you can find competitive wholesale pricing, but always factor in potential import duties when buying abroad.

Belgium: The Heart of the Global Diamond Trade
Known as the diamond capital of the world, Antwerp handles a significant portion of the world's rough diamonds. The city's diamond district is a bustling hub where buyers can explore a vast selection of diamonds at various price points.
However, diamonds have more or less become a commodity – that is an Australian diamond merchant can buy the same stone as an American diamond merchant for the same price. Unlike other industries, there are no notable “bulk discounts” in the diamond industry, except for smaller diamonds (under 25pts).
Antwerp, Belgium, is often considered the epicenter of the global diamond trade. Home to the famed Antwerp Diamond District, the city processes over 80% of the world's rough diamonds and approximately 50% of all polished diamonds.
A 1 carat diamond ring in Australia in 2025 typically ranges from AUD 5,000 to AUD 12,000 for a natural diamond, depending on its cut, colour, and clarity. For a lab-grown alternative of comparable visual quality, expect prices between AUD 1,800 and AUD 6,000.
Let's take a closer look at the top three diamond-producing nations:
A 1-carat diamond in Australia generally costs between A$2,000 and A$20,000+, but can range from under $1,100 for lower-grade stones to over $18,000 for high-quality, well-cut diamonds, with the price heavily influenced by the "4 Cs": Cut, Colour, Clarity, and Carat, plus the diamond's shape and if it's natural or lab-grown (lab-grown being much cheaper). For example, you might find a lower-clarity, M-color oval for around $1,000, while a D-color, VVS1 princess cut could be over $11,000.
Diamonds Factory (and similar retailers) seem cheap in Australia primarily because they're direct manufacturers with efficient supply chains, cutting out middlemen to reduce costs, and they heavily feature affordable, chemically identical lab-grown diamonds that are significantly cheaper than natural ones. Their low prices stem from bypassing traditional retail markups and leveraging the lower cost of lab diamonds, offering better value for money, not necessarily inferior quality.
Diamonds are thought to have been first recognized and mined in India, where significant alluvial deposits of the stone could be found many centuries ago along the rivers Penner, Krishna, and Godavari.
At times, you can find quality diamond rings or jewelry in Dubai that is more than 30% cheaper compared to some other countries.
Diamonds in Australia were recorded in the Bathurst area, New South Wales in 1851. Significant quantities also were mined from alluvial deposits at Copeton and Bingara, near Inverell in north-eastern New South Wales, from 1867 to 1922 and minor production resumed at Copeton in 1997, but has since stopped.
Ranking number one as the most affordable diamond shape, cushion-cut diamonds are a great choice for an elegant yet price-conscious purchase. Price-savvy brides adore cushion cut diamonds and this elegant shape has been experiencing a serious revival in popularity over the last few years.
Engagement rings tend to be the cheapest during November and December, as well as the off-peak summer months like July and August. During these periods, many jewelers offer seasonal promotions or clearance sales to attract holiday shoppers or boost slower summer traffic.
There are three famed diamond mines in Australia: Argyle, Ellendale and Merlin. Combined, the mines have supplied millions of carats worth of gems to the global market, and individually they have produced some of the rarest, most exquisite stones ever recovered.
The Aquamarine name comes from the Latin word for seawater and is said to calm waves and keep sailors safe at sea. It is sometimes referred to as a poor man's diamond because of the pale color.
For a $5,000 budget, you can typically get a natural diamond engagement ring with a center stone around 0.75 to 1.0 carat, possibly slightly larger (up to 1.2 ct) in elongated shapes like pear or oval, depending on cut, color, clarity, and the setting's cost, with lab-grown options allowing for much larger (3-4+ carat) stones or alternatives like moissanite offering bigger stones within budget.
For $20,000, you can typically get a significant diamond, often ranging from 1.5 to over 2.5 carats, depending on the Four Cs (Cut, Color, Clarity) and shape, with choices like a 2ct H VS2 or a larger but less perfect 2.5ct I SI1 being common, or even larger lab-grown options. A strategic approach balancing quality (excellent cut, near-colorless) with size allows for a visually stunning, large stone that sparkles brilliantly, rather than overpaying for perfect color/clarity invisible to the naked eye.
The Moussaieff Red Diamond
Weighing 5.11 carats, this is the largest known red diamond, making it exceptionally rare. Red is the rarest color classification for diamonds, and stones of this size and purity are virtually unheard of.
Yes, lab-grown diamonds are real diamonds, possessing the exact same chemical composition (pure carbon), physical properties, and optical characteristics as natural diamonds, just with a different origin story. The only real difference is that one is grown in a laboratory by mimicking Earth's conditions (HPHT or CVD), while the other is mined from the ground, making lab diamonds a more affordable and sustainable choice, though they often have lower resale value.
Benefits to buying Russian diamonds
Jewelers often sought out stones from cutters whose craftsmanship aligned with high-end, luxury aesthetics. Over time, these cutting traditions developed reputations for producing diamonds that were durable, well finished, and capable of lasting for generations.
One of the main reasons for this concern is that diamond mines are not infinite resources – eventually, they will run out. As Gemological Institute of America research scientist Evan Smith says, “For every diamond you take out of the ground, there's one fewer to be found.”
