Oldest Minerals on Earth: Jack Hills Zircon Rock Metaconglomerate

Own a direct connection to the earliest history of our planet with this giant Jack Hills zircon metaconglomerate specimen from Erawondoo Hill, Western Australia. Containing zircon crystals dated to approximately 4.4 billion years, this rare geological treasure preserves the oldest minerals on Earth and is considered one of the most important Hadean Eon rocks ever discovered.

Highly sought after by collectors, museums, and scientists, Jack Hills zircon is valued as both an authentic geological specimen and a museum-quality science collectible.

Geological Significance of the Yilgarn Craton

This specimen originates from the Narryer Gneiss Terrane of the Yilgarn Craton, an ~80 km belt of folded and metamorphosed supracrustal rocks in Western Australia.

The zircons from this region are world-renowned for U–Pb crystallization age dating, with several grains measured at 4.4–4.3 Ga—the oldest reliably dated minerals on Earth. Their oxygen isotopic compositions suggest that liquid water may have existed on Earth’s surface more than 4.3 billion years ago, providing direct evidence of an early Earth’s crust and earliest oceans.

Owning a specimen like this gives you a rare opportunity to have one of the very oldest rocks on Earth.
