Rubies are among the world's most coveted gemstones, prized for their vivid red hues and long history across many cultures. While not as well-known as sources such as Myanmar and Sri Lanka, Australia is indeed home to ruby deposits, primarily located within the rugged terrains of New South Wales and Queensland. The New England area of New South Wales and the Central Queensland gemfields are particularly notable for ruby discoveries, often found alongside sapphires in mineral-rich grounds. These rubies offer a unique insight into Australian gemology, with distinct colour properties and geological formations that set them apart from their counterparts in other regions.
| Characteristics | Values |
|---|---|
| Ruby deposits in Australia | Deposits are primarily located in the rugged terrains of New South Wales and Queensland |
| Mining history | Discoveries were often short-lived and overshadowed by more profitable gemstones like sapphires and opals; small-scale operations and artisanal miners are common |
| Geological associations | Corundum, the mineral species to which rubies belong, is linked to metamorphic rocks and alluvial deposits |
| Genesis | High pressure and temperature conditions associated with the tectonic and metamorphic history of the Australian continent |
| Specific locations | New England area of New South Wales, Central Queensland gemfields (Anakie, Rubyvale), Inverell, Glen Innes, Oberon, Goulburn, Kings Plains |
| Ruby characteristics | Distinctive colour and clarity, though may not reach vivid red hues of other deposits; contain chromium which impacts colour and value |
| Grading | Rated 9 on the Moh's scale of hardness; colour is the main factor for grading |

New England, New South Wales
Rubies can be found in the New England area of New South Wales, particularly around Glen Innes, which is known for its mineral-rich grounds and historical mining activities. Rubies in this region are often recovered from alluvial deposits, alongside sapphires. The New England area has been a site of mining activity since the early 20th century, with commercial mining beginning in 1919.
The discovery of rubies in Australia often occurred when prospectors were seeking other gemstones or minerals, leading to short-lived rushes that ended when miners realised the variable quality of the rubies. The country's ruby deposits have never been fully exploited, as they are often overshadowed by more profitable and abundant resources such as sapphires and opals.
The rubies found in the New England area of New South Wales are characterised by their unique colour properties and geological formations, which differ from those of rubies found in other parts of the world. They are geologically associated with metamorphic rocks and alluvial deposits, and their genesis is linked to the tectonic and metamorphic history of the Australian continent, which provides the necessary conditions for ruby formation, namely high pressure and temperature.
The mining operations in the New England area are typically small-scale and employ basic methods of extraction, such as open-pit mining, where jackhammers, excavators, or shovels are used to extract the corundum ore from the gravels. This aligns with the broader historical context of Australian gem mining, which is characterised by artisanal miners rather than large-scale industrial entities.

Central Queensland gemfields
The Gemfields, located in Outback Queensland, is a great destination for travellers seeking unique experiences. The region offers a range of gem-related attractions, such as gem shops, fossicking parks, and tag-along tours. Visitors can try their luck at fossicking for sapphires, rubies, and zircons in designated areas. Fossicking licences are required and can be purchased online. The Gemfields also has essential amenities, including pubs, coffee shops, caravan parks, and grocery stores.
The Central Queensland Gemfields covers almost 900 square kilometres and is one of the largest sapphire-bearing areas globally. The sapphire gemfields are a 45-minute drive west of Emerald, a town named after the lush green pastures that surrounded it. The nearby Lake Maraboon, Queensland's second-largest lake, is also a popular attraction.
The history of ruby mining in Australia has been characterised by opportunistic exploitation rather than systematic development. The Central Queensland Gemfields, with its ruby deposits, has been overshadowed by more profitable and abundant resources like sapphires and opals. The mining processes have typically been small-scale operations using basic extraction methods, reflecting the broader context of Australian gem mining dominated by artisanal miners.

Glen Innes
Rubies are among the precious gemstones found in Australia, particularly in the rugged terrains of New South Wales and Queensland. The New England area of New South Wales, around Glen Innes, is known for its mineral-rich grounds and historical mining activities.
The Glen Innes Visitor Information Centre is a great place to start for those interested in fossicking in the area. The centre offers advice and information on fossicking sites, some of which require a day's advance notice. The Emmaville Mining Museum, located in the area of Emmaville or Torrington, is another valuable resource for local knowledge on fossicking. The museum houses a impressive collection of gems and minerals, as well as a replica blacksmith's shop, an old wood-fired bakery, and a machinery shed filled with old mining equipment.
The Minerama Fossicking, Gem & Jewellery Show, held in Glen Innes, is NSW's largest annual gem and jewellery show, attracting visitors and dealers from across Australia. The event caters to gem and jewellery enthusiasts, rockhounds, and outdoor adventurers, offering a diverse range of gemstones, jewellery, crystals, fossils, and more. Glen Innes is also home to Aussie Sapphire Lapidary Warehouse, an online lapidary business that provides a wide range of supplies for working with rock, glass, or metal.

Inverell
Rubies can be found in Australia, particularly in the New England area of New South Wales and the Central Queensland gemfields. The New England area, specifically around Glen Innes and Inverell, is known for its mineral-rich grounds and historical mining activities.
The exploration and extraction of rubies in Australia have a relatively modest history compared to other gemstones. The country's ruby deposits have often been overshadowed by more profitable and abundant resources, such as sapphires and opals. The mining of rubies in Australia has primarily been opportunistic rather than systematic, with small-scale operations employing basic extraction methods.
The Gem Centre, a family-owned business located in the heart of Inverell, showcases a range of local sapphires and other gemstone products. While rubies may not be their primary focus, the presence of gemstone businesses in the area reflects the local culture and industry surrounding gemstones in Inverell.

Anakie
The Central Queensland Gemfields, which encompasses the locality of Anakie, is a well-established source of corundum gemstones, including rubies. Anakie, along with Rubyvale and Sapphire, is known as the "Gateway to the Gemfields". These three settlements were established to meet the demands of miners and facilitate the search for precious stones.
The Central Queensland Gemfields are a significant source of corundum, which is brought to the surface in igneous rocks that are high in aluminium but low in silicon, such as basalts. The basaltic, volcanic rocks in Eastern Australia are a major source of corundum, but the minerals are rare and not commonly mined directly from these rocks. The gemstones are usually extracted using traditional mining techniques, including sifting and washing the soil and sediment.
The evaluation of ruby quality considers factors such as colour, clarity, cut, and carat weight—the traditional four Cs of gemstone assessment. Australian rubies typically exhibit a spectrum of quality, ranging from opaque and heavily included specimens to those of reasonable clarity and colour saturation.
