Our Pearls

Before there is craftsmanship, there is patience.

Kailis pearls are unlike any other on Earth. Born from the rare Australian Pinctada Maxima oyster – the largest of all pearl-producing oysters in the world – our Australian South Sea pearls have the thickest nacre and a lustre, colour and size to rival any other. It is no wonder then that this level of natural beauty does not happen overnight. The Pinctada Maxima produces one cultured pearl every two to three years. Imagine what it takes to find the perfect pair.



After patience, there is selection.

In itself, the Australian South Sea pearl is a rare miracle of nature, making up just 0.1% of global pearl production. However, at Kailis we take this further and select only premium quality pearls from this limited production to craft our magnificent jewellery. There is no doubt, a Kailis Australian South Sea pearl is one of the rarest and most valuable natural gems in the world.

After selection, we do nothing else.

The beauty of a fine quality pearl is revealed the moment it is removed from the oyster. Because at Kailis we choose only the best of the best, we do nothing to our pearls. No colour or lustre enhancement, no elevation of features, no treatment of any kind. There is no need. A Kailis Australian South Sea pearl will never fade, lose colour or feel, because it is authentic, untouched, and naturally radiant.

Above all, there is heritage.

In investing in a Kailis Australian South Sea pearl, you are investing in the future. Due to gross over-fishing in other areas, Australia is now the only place on Earth where the Pinctada Maxima can be used for pearl cultivation. Thanks to strict regulations ensuring sustainable processes, the wild pearl fisheries of Western Australia and the Northern Territory are the first in the world to be certified by The Marine Stewardship Council. Australia’s pearl beds are healthier now than they have been for more than a century and we commit to sustaining this national legacy.



Unique to this precious gem, lustre is the radiant quality of the surface as light reflects through the countless layers of nacre within the pearl. Australian South Sea pearls have the most naturally illuminating lustre of all pearl types, it will never fade and requires no additional treatment.


While a pearl with a flawless surface is exceptionally rare, the quality of complexion is influenced by the number and size of imperfections and their degree of visibility.


Our pearls come in a variety of shapes. These include the incredibly rare, perfectly round pearls and unique shapes such as baroque and circle pearls. Keshi, drop, oval and button shapes are also found in our jewellery designs.


Typically mirroring the overtones of the pearl shell, Australian South Sea pearls come in a variety of natural colours including white, silver and cream. Look closely enough and some exhibit pink, blue and even green hues, mirroring the uniqueness of the shell they laid in. While colour is a very personal choice, white with pink overtones is the most prized variety.


Measured in millimetres by width, size is the last of the assets to consider. Australian South Sea pearls, blessed with a naturally thick nacre, are the largest of all the world’s pearls, typically ranging from 11 mm to 16mm. Highly prized yet exceptionally rare pearls of up to 20mm are also occasionally produced.

The Five Virtues

Every Kailis Jewellery pearl is hand-selected based on five natural virtues of lustre, shape, size, colour and surface quality.

Each pearl is graded in line with its virtues. Our Australian South Sea pearls are available in brand 1, 2 and 3. Brand 1 pearls are the rarest and are naturally of higher value.
