Size is the first thing you notice with this piece. At 45×22mm, it's the largest stone in this Zebra Rock series — wide enough to carry the full rhythm of the banding without any rushing. The natural stripes run dark brown to light, laid down in the Precambrian and polished to a soft satin finish that lets the pattern breathe rather than shine. The sterling silver top loop sits clean against the stone's width, keeping the setting minimal so the geology stays front and centre. This is a statement piece — not because of embellishment, but because of scale and pattern working together.

About Zebra Rock

Zebra Rock is a banded sedimentary stone found only in one region of the world — the East Kimberley in far-northern Western Australia, near Lake Argyle and Kununurra. It formed roughly 600 million years ago in the Ranford Formation, and its distinctive look comes from natural rhythmic bands of iron-oxide-rich reddish-brown alternating with paler cream and white argillaceous siltstone. Each piece is a slice of Precambrian Australia. The stone polishes to a soft satin finish and the bands run in directions unique to that piece — no two stones share the same pattern. It's not crystalline like opal; it's the geological record itself, made wearable.

Common Questions

Does it come with a chain?
No — this pendant comes with the sterling silver bail only. It fits any standard chain with a jump ring up to approximately 4–5mm wide. If you'd like a chain recommendation, get in touch.
What makes Zebra Rock different from other banded stones?
Zebra Rock is geologically specific — it forms only in the Ranford Formation of the East Kimberley in far-northern Western Australia, making it genuinely rare outside that region. The banding is a natural sedimentary rhythm from roughly 600 million years ago, not a dye or treatment. No two stones carry the same stripe arrangement, width, or direction.
Is it a gemstone or a mineral specimen?
It sits somewhere between the two. Zebra Rock is an argillaceous siltstone — a sedimentary rock rather than a crystalline mineral — but it's been cut and polished to jewellery grade. Think of it the way you'd think of a fine piece of petrified wood or jasper: natural, geological, and entirely wearable.
