This 2.72ct Green-Blue Australian Sapphire was sourced as rough and cut in house by The Sapphire Merchant.
The stone displays a beautiful combination of rich green and blue tones, with flashes of brighter teal bringing the colour to life. Its cushion cut gives it a classic, balanced shape, while the brilliant crown and step-cut pavilion create an attractive contrast of sparkle and depth.
What makes this sapphire particularly appealing is its distinctly Australian colour. The blend of blue and green has a richness and complexity that sets it apart from more conventional sapphires. At 2.72ct, it offers a generous size and would make a striking centre stone for a bespoke ring or pendant.
Completely natural and unheated, this sapphire has been certified by GFCO Gem Lab and retains its original colour, untouched by heat treatment.

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.
