Australian Tiger Iron Heart - 01

Tiger iron from the Pilbara region of Western Australia is a striking metamorphic rock composed of alternating layers of golden tiger’s eye, silver-grey hematite, and deep red jasper.

These minerals are arranged in rhythmic banding, a result of ancient sedimentary layering that was later transformed by intense heat and pressure. Its formation began over 3 billion years ago, during a period of early Earth’s evolution when iron and silica accumulated in ancient seas.

Over time, tectonic activity folded and compressed these layers, creating the distinctive patterns seen today. Tiger iron not only showcases the dynamic forces that shaped our planet’s crust, but also serves as a tangible record of Earth’s early geological history and atmospheric development.

At Uluna, we are deeply committed to offering crystals that are not only beautiful but also ethically sourced and of the highest quality. Ethical sourcing means ensuring that the crystals we provide are mined under fair conditions, respecting both the environment and the workers involved. We also recognise that many crystals undergo processes like cutting and polishing in  factories far away from their mined locations, so we remain diligent about maintaining our integrity throughout the supply chain sourcing locally and directly where possible.

Our dedication to quality is upheld by our in-house gemmologist, who brings over 15 years of expertise to every piece we offer. Each crystal is carefully tested, correctly identified, and certified as natural, with any treatments fully disclosed. Unlike lab-grown or misrepresented stones often sold as natural, our crystals are authentic and come with an authenticity card, guaranteeing their provenance and purity so you can feel safe with each purchase. For us, ethics and quality are non-negotiable values.
