Australian Sapphires
Australian sapphires are prized across Australia and New Zealand because they are unearthed from the red soil beneath us. Mined from the historic sapphire fields of New South Wales and Queensland, including Inverell, Glen Innes, and Anakie, these natural sapphires display a rich spectrum of deep blue, teal, green, yellow, and the highly sought-after Australian parti sapphire. Formed in basalt lava flows millions of years ago, Australian sapphires are renowned for their inky colour saturation, making them an ideal choice for engagement rings and custom sapphire designs.
Commercial sapphire mining in Australia began in the late 1800s, with the country becoming one of the world’s leading sapphire producers throughout the 20th century. Today, Australian sapphire mining is heavily regulated, with strict environmental management and land rehabilitation standards in place, a key consideration for ethically minded jewellery buyers in Australia and New Zealand. Valued for their ethical sourcing, durability, and bold natural colour, Australian sapphires remain a favourite among custom jewellery clients across Australasia seeking gemstones of integrity and enduring beauty.
