Ethical Production

Australian Sapphires

At Corky Saint Clair, we pride ourselves on using ethically sourced materials, and our collection of Australian sapphires is no exception. We work closely with local cutters and fossickers to source the finest sapphires that are as stunning as they are durable.

By buying locally, we ensure a shorter chain of provenance, giving us greater control over the quality of our materials.

In addition to our sapphires, we also offer a range of other Australian gems, including diamonds, zircons, garnets, and topaz. Our commitment to ethical sourcing means you can feel good about your purchase while enjoying the beauty of these unique and rare gems.

Recycled Metals

At Corky Saint Clair, we believe that beautiful jewellery shouldn't come at the expense of the environment. That's why we're committed to using 100% recycled metals in all of our pieces.

We partner with Lenrose Pty Ltd, a metal supplier that shares our commitment to sustainability and ethical responsibility. By using recycled gold and sterling silver, we can ensure that our materials are not only beautiful but also environmentally friendly.

Recycled metals are identical in colour and composition to mined metals, so you can rest assured that your piece will be just as stunning and durable as if it were made from newly mined materials. And because our metals come from reclaimed sources such as old jewelry, coins, and silverware, we can help reduce the environmental impact of mining and preserve precious resources.

Ethically Sourced Diamonds

At Corky Saint Clair, we are committed to ethical sourcing and only use diamonds that have been responsibly and ethically obtained.
Our collection includes Australian diamonds as well as other non-traditional specimens from the diamond family, such as salt and pepper diamonds, rough-cut diamonds, and macle diamonds.
Australian Diamonds
We have a large collection of Australian diamonds from the renowned Argyle Mine in Western Australia. These diamonds range in colour from 'champagne' to 'cognac' and have a warm look with an incredible sparkle.
We have a range of Australian diamonds on hand and can also order in larger gems for you. We also have limited amounts of natural white Australian diamonds to use as accents stones if you want your ring to be 100% Australian.
Salt and Pepper Diamonds
Our Salt and Pepper Diamonds are particularly special, and we take great care to source only the finest quality stones from India. These diamonds are then precision-cut in Antwerp to bring out their natural beauty and unique character.
White Diamonds
We are proud to say that all of our white diamonds comply with the Kimberley Process, which ensures that they have been obtained through legitimate and ethical means.
When you choose a diamond from Corky Saint Clair, you can feel confident that it has been sourced with care and consideration for both the environment and the people involved in its production.If you're interested in learning more about our diamond collection or would like to discuss a bespoke piece, please contact us at
