At 47×20mm, this is a long, slender stone — narrow enough to sit like a brushstroke down the neckline, long enough to draw the eye properly. The banding runs in natural alternating stripes of dark brown and light brown, a pattern formed not by a jeweller's hand but by 600 million years of sediment laid down in the East Kimberley. The stone is polished to a soft satin finish that lets the banding speak without glare. Hung from a sterling silver top loop, it wears simply and rests well against both pale and warm skin tones. This is not a flashy stone. It is a very old one.

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.

Caring for Your Zebra Rock

Zebra Rock is a dense, non-porous siltstone — it doesn't absorb water or oils the way softer stones do. The sterling silver bail benefits from the same general care you'd give any silver piece: keep it away from harsh chemicals, chlorine, and abrasive cleaners. To clean the stone itself, a soft damp cloth is all that's needed.

Common Questions

Does it come with a chain?
No chain is included — this pendant comes with the sterling silver bail (top loop) only. The 47×20mm stone suits a chain of 45–50cm (18–20 inches) at a standard width of 1–2mm. Any compatible chain with a lobster clasp or similar fastener will fit the bail.
What exactly is Zebra Rock? Is it a gemstone?
Zebra Rock is a sedimentary stone, not a crystalline gemstone — it's an ancient banded siltstone, roughly 600 million years old, found only in the East Kimberley region of Western Australia. It's classified as an ornamental stone rather than a precious or semi-precious gemstone in the traditional sense, but it's genuinely rare: the only deposit of this particular banded formation is near Kununurra and Lake Argyle. Its value comes from geological uniqueness, not scarcity manufactured by a market.
Is the silver setting sterling silver?
Yes — the bail (top loop) is sterling silver, meaning 92.5% pure silver alloyed for durability. It's the standard used in quality jewellery-grade silver settings.
Certification, shipping, returns?
Every piece is backed by Joseph's personal guarantee, ships fully insured within Australia, and can be returned within 14 days. See Buying an Opal for the full breakdown.
