Australian Gemstones: The Sparkling Top five

Australia is home to some of the world’s premier gemstone mines. From the iconic Argyle Diamond Mine in Western Australia to Sapphires in New South Wales and Queensland, there are an array of gemstones right here in our backyard.

Here we explain some Australian gemstones available here...


Diamonds in Australia are sourced from the Argyle diamond mine located in the East Kimberley region in Western Australia. Being one of the world’s largest diamond and coloured diamond producers (by volume), the Argyle Diamond mine has produced over 800 million carats of rough diamonds.

An Argyle Pink Diamond is considered ‘beyond rare’. For every one million carats of rough diamonds mined, only one carat of pink diamonds will be suitable for sale.

It’s the exclusivity and beauty of these Argyle Pink Diamonds that make them a wonderful statement, and also an ideal investment.

South Sea pearls are grown in Australia’s northern waters, in Broome, Western Australia, and have been harvested in Australia since the 19th century.

The Australian pearls are fine gemstones and can be found in various shades such as cream, gold and pink.

The national gemstone of Australia, the Opal is an interesting and impressive gemstone. With over 90% of the world’s opals found in Australia and no two the same, opals display a magnitude of colours and variety of opals, including boulder, matrix, black, crystal and white opals.



Although Australia is best known for its opal and diamond production, New South Wales and Queensland produce a variety of sapphires. With the blue variety being the most common gemstone offered, sapphires are actually available in an array of colours.

Australia produces a large amount of Parti Sapphires, which feature a unique colour - reflecting both the yellow and blue colour.

Sapphires are available in a rainbow of colours and are beautifully complemented by natural glistening diamonds. Sapphire engagement rings continue to gain attention with couples starting to entertain the idea of coloured stones in their engagement rings.
