Polished Pilbara Agate Slice from Western Australia, measuring approximately 2 inches. This vivid specimen reveals swirling bands of orange, tan, and white chalcedony — a naturally artistic pattern formed in ancient volcanic deposits of the Pilbara Craton, one of the oldest geological formations on Earth.

This Pilbara Agate Slice originates from the Pilbara region of Western Australia, a geologically ancient landscape known for its mineral wealth and striking agate deposits. These agates formed within gas cavities of rhyolitic volcanic rock over two billion years ago, as silica-rich fluids slowly deposited microcrystalline quartz (chalcedony) in rhythmic layers.
The Pilbara Craton — one of Earth’s oldest continental fragments — provides a glimpse into the Archean Eon, when the planet’s crust was still forming. Agates from this region are known for their deep earth tones, strong banding, and translucence, often with subtle iron staining that adds warmth to their palette.

Pilbara Agate formed as volcanic gases created vesicles in cooling lava flows. Over millions of years, groundwater saturated with dissolved silica filled these cavities, creating agates through layered chalcedony deposition. Iron and manganese oxides later introduced red and brown tones.
This slice features tight concentric bands and a mirror polish on both sides — showcasing its semi-translucent nature under backlighting. Subtle color transitions from cream to amber make each Pilbara specimen completely unique.
Pilbara Agate is a favorite among collectors for its connection to ancient geology and its painterly banding. This slice’s thin polish allows light to pass through, revealing color depth and flow lines reminiscent of desert horizons.
An ideal display piece for collectors, educators, or interior stylists who value natural geological art.
Display specimen for mineral collections or geological teaching.
Decorative slice for light stands or lapidary framing.
Photography or design prop showcasing organic symmetry and color flow.
Pilbara Agate is said to embody grounding, strength, and ancestral connection — reflecting the deep age of the Australian continent itself. Symbolically, it supports endurance, creativity, and stability during times of transformation.
Clean gently with a soft, dry or damp cloth.
Avoid harsh chemicals or ultrasonic cleaning.
Display away from prolonged direct sunlight to maintain color integrity.
