About New Zealand Thunder Eggs

Thunder eggs form as spherical rocks within rhyolite lava, containing a star-shaped quartz or agate centre. While thunder eggs are found globally (most famously in Australia and the USA), authentic New Zealand specimens are exceptionally rare, making them highly sought after by local and international collectors alike.

• Locality: Sourced from small, agate-filled nodule sites such as Rangiatea Station — private and largely inaccessible locations in the South Island
• Appearance: Hard, rough volcanic exterior concealing a complex interior filled with starburst agate, quartz, or amethyst with vibrant natural colours
• Significance: True thunder egg localities are rare in New Zealand, making each specimen a unique collector's piece
• Availability: Authentic New Zealand thunder eggs are rarely available — this is a genuine opportunity to own one

Each thunder egg is a one-of-a-kind natural specimen. The piece you see is the piece you receive.
