This pendant contains a polished piece of tiger iron, a form of banded iron from Western Australia. Tiger iron from this location formed 3,020,000,000 years ago during the Great Oxygenation Event, a period where cyanobacteria photosynthesized massive amounts of free oxygen, creating the atmosphere we breathe today.

The beautiful necklace centerpiece measures 1.44" in length along its longest side. It has been specially prepared to bring out the brilliant reds, yellows, and oranges present in the 3 billion-year-old material. The tiger iron is set into a sterling silver backing and includes an 18" chain. It also ships with an informational card.
