Why Australian Sapphires?

Australian sapphires are beauty with integrity.

Responsibly mined, thoughtfully faceted, and fully traceable, they carry the colours and character of our landscape - from deep rainforest greens to shifting teal parti tones unique to Australia alone.

Each stone is ethically sourced from small, family-run miners and cutters across Queensland and New South Wales, ensuring fair practices, low-impact extraction, and genuine transparency.

When you choose an Australian sapphire, you’re choosing a gemstone with a clear origin, an honest story, and a brilliance shaped by the earth itself.

This is my fifth purchase from The Sapphire Theory. Each was a dream ring. Georgous stone, organic style, infinitely wearable, unique and ultimate heirlooms if you can pry them off my cold dead hands.

I had been eyeing this piece off for so long and finally decided to get it as a 30th present to myself. I wear this ring every single day and (other than my engagement ring 😆) is my absolute favourite piece of jewellery that I own. I always get compliments on it!

Holly Sutton

I honestly couldn’t be more delighted with my engagement ring! Ethical consideration was a huge factor in selecting The Sapphire Theory as I loved that my stunning sapphire was fully ethical and traceable, along with the gold. I also needed something strong and durable as I want to wear my ring every moment of my life and so Selena’s lost wax method was perfect, creating a beautiful, but strong piece that will truly last a lifetime without compromising on beauty. The stones that Selena has access to are incredible and so individual, you know that no one else will have a ring exactly like yours, and I love that. I’ve now been wearing my engagement ring for over 18 months and it still looks perfect. I also ordered from England and Selena was super helpful with the tracking of my ring as it travelled across the world.

If you want something unique, ethical and utterly beautiful, please order one of Selena’s rings. I am incredibly happy that we chose ours from The Sapphire Theory and would highly recommend them!
