Sapphire mining in Australia
Australia was once the source of most of the world's sapphire. This is where those stones come from, how they're found, and how the fields work today — across the three states that produce them.
The country that quietly supplied the world
For much of the twentieth century, Australia was the largest source of sapphire on earth — at its peak in the 1980s, supplying an estimated 70 to 90 percent of the world's commercial-grade stones. Much of it left the country as rough, was cut and heat-treated in Thailand, and was sold on without its origin ever being named. A great deal of the sapphire the world thought of as 'Thai' or 'Ceylon' in that era was, in fact, Australian.
We work with Australian sapphire because we can stand close to where it comes from. This page is the longer story behind that — the geology, the fields across Queensland, New South Wales and Tasmania, how the stones are mined, and how you can go and look for them yourself.
Why Australian sapphire looks the way it does
Every sapphire field in Australia traces back to the same kind of event: ancient volcanic activity along the eastern edge of the continent. Molten alkali basalt carried corundum crystals up from deep in the crust and spread them across the landscape, where millions of years of weathering and water concentrated them into the riverbeds and buried gravels that miners work today.
Because that basalt is rich in iron, so are the sapphires. The iron is what gives Australian stones their characteristic depth — strong blues, vivid greens and golden yellows — and the famous parti-colours, where blue, green and yellow meet in a single stone.
Three states, three characters
Sapphire turns up down most of Australia's eastern seaboard, but three regions account for nearly all of it. Each has its own colour signature and its own history. (Add field entries as blocks below and tag each to a state.)
Queensland
Queensland holds Australia's largest and most famous fields, known for the full sweep of colour — light and bright to deep blue, golden yellow, green, sometimes pink/purple, and the parti-colours the country is celebrated for.
New South Wales
The New England fields of northern New South Wales are prized for Australia's finest blue — clean, even stones that hold their colour from almost every angle.
Tasmania
Tasmania's sapphire is smaller in scale and is the domain of fossickers, but the island's north-east produces genuine, characterful stones alongside its classic heavy minerals.
From a surveyor's lucky find to most of the world's supply
Australian sapphire was found by accident, built into a global industry, nearly forgotten, and is now being rediscovered. The short version runs like this. (Add or edit milestones as blocks below.)
The first Australian sapphires turn up in the pans of gold miners on the Cudgegong and Macquarie rivers in New South Wales — heavy blue pebbles, most of them thrown back.
Government surveyor Archibald Richardson finds sapphire near Anakie while surveying the railway, quits his job, and starts digging. Commercial production follows around 1891, and Anakie is declared a mining field in 1902.
Russian and German buyers work the Queensland fields. The darker royal blues are favoured by the Tsarist Russian court, and some Russian crown jewels are believed to contain Anakie corundum. The First World War brings the first boom to an end.
Commercial mining begins in the New England fields at Frazers Creek near Inverell in 1919, pauses through the Great Depression, and resumes in earnest from 1959 as South-East Asian supply tightens.
Thai buyers arrive in force, and Thai heat treatment turns previously unsellable dark rough into faceted gems. Production booms from 1967, mechanises, and by the 1980s Australia is supplying an estimated 70 to 90 percent of the world's commercial sapphire — most of it cut and sold abroad without its origin named.
As Thailand, China, Nigeria and then Madagascar ramp up, Australia's share falls away. Many operations close or shrink to small-scale and family mines, though the best fields keep producing throughout.
Fura Gems acquires major Central Queensland operations and reopens large-scale mining. The Richardsons continue high production with a focus on traceability, while jewellers and buyers rediscover Australian sapphire as a transparent, ethically grounded source.
Finding the wash
Almost all Australian sapphire is alluvial — concentrated by ancient rivers into a gravel layer miners call the 'wash', often buried under metres of soil. The work, at every scale, comes down to reaching that layer and separating the heavy sapphire from everything else. Only a fraction of what's recovered is gem quality. (Add method cards as blocks below.)
Specking & hand tools
Specking is the simplest way to find sapphire — and strictly speaking it isn't mining at all. It's walking the ground and picking stones straight off the surface, usually after rain has washed away the topsoil. Hand tools come next: a pick, a spade and a sieve, often paired with a home-built rig that separates gravel faster than a sieve alone.
Shaft mining
A shaft is sunk to the sapphire-bearing layer, which can sit as deep as fifteen metres. Since the 1970s the digging often starts with a truck-mounted drilling rig; from there, miners work the wall by hand, following the course of the ancient riverbed underground.
Mechanised wash plants
Larger operations strip down to the wash and run it through trommels and jigs that use water and density to pull the heavy sapphire out of the gravel. The concentrate is then hand-sorted — stone by stone, by eye.
Open cut
Open-cut is the rarest method on the Australian fields because it needs serious machinery. Topsoil is stripped and stored for later rehabilitation, then bulldozers work down to the sapphire layer. High cost — but it can yield sapphire in real volume.
Fossicking, state by state
One of the best things about Australian sapphire is that you can go and find your own. The rules differ by state — here's the short version.
A fossicking licence is required throughout Queensland, and you may only fossick in designated fossicking areas — not on active mining claims without the holder's permission. Licences are inexpensive and issued online. The Central Queensland Gemfields around Rubyvale and Sapphire have well-marked public areas to start in.
Recreational fossicking on much Crown land needs no licence under the Mining Act 1992. But you'll need the manager's permission on managed or leased Crown land, a separate permit for State forests, and the owner's consent on private land. Hand tools only.
No licence is needed within Tasmania's declared fossicking areas, including the Weld River in the north-east. To fossick anywhere outside those areas you need a prospecting licence. Conditions apply — generally hand tools only, and no digging into natural stream banks.
These are summaries, not legal advice — and licensing, fees and access do change. Confirm the current rules with Business Queensland, the NSW Resources Regulator and Crown Lands, or Mineral Resources Tasmania before you head out.
Why we source where we do
Our own footage and our closest miner relationships are in the Central Queensland Gemfields, around Rubyvale. Working that close to the source means we see how the ground is treated firsthand — topsoil set aside and replaced, worked ground rehabilitated, and the people doing the work paid fairly for it.
Australian sapphire is also mined under some of the strongest labour and environmental laws of any source in the world. That, plus direct contact rather than a certificate passed down a long supply chain, is what lets us speak honestly about where a stone came from and how it was won.
We would rather know the person who dug a stone than trust a label that says someone else checked.
Stones with a place of origin
Every Australian sapphire we offer began in the gravel of one of these fields, found by someone with a sharp eye and a great deal of patience.
When so much of the world's sapphire still travels anonymously, being able to name the country — and often the very field — a stone came from is rare. It is the part of Australian sapphire we value most.
