This 2.38ct Green-Blue Australian Sapphire was sourced as rough and cut in house by The Sapphire Merchant.
The stone has a deep blue-green colour with a distinctly Australian character. Internal silk shifts between green and blue depending on the light, giving it a moody, natural presence rather than a standard sapphire look.
Its oval shape keeps the design elegant and wearable, while the brilliant crown adds flashes of light across the face of the stone. The colour has depth and individuality, making it a strong choice for someone wanting a sapphire that feels refined but a little different.
Completely natural and unheated, this sapphire retains the colour it formed with in the earth. It would make a beautiful centre stone for a custom ring, pendant, or bespoke jewellery design.
Buy this natural unheated Australian sapphire as a loose gemstone or custom design a jewellery piece with The Sapphire Merchant.

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.
