Zircon crystals in this rock have been dated to 4.4 billion years old, formed during a young Earth's earliest Hadean era. The Jack Hills formation in western Australia they come from is now a cultural heritage site closed to new mining, so these are among the only specimens that will ever be available. Each display contains a 1\" glass jar with several samples of this quartzite rock that aren't much larger than grains of sand.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAcasta Gneiss: The oldest known crustal material on Earth.\u003c\/strong\u003e The Acasta Gneiss is the oldest known fragment of Earth's ancient crust, dating up to 4.03 billion years old. Exposed on a remote island in Canada’s Northwest Territories, the site is so inaccessible that reaching it requires chartering a bush plane with specialized personnel and equipment. Only small quantities can be retrieved under strict conditions, making each specimen exceptionally rare and scientifically invaluable—a tangible piece of the Earth's deep past. Each display contains a specimen jar with a small fragment of this rock\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMorton Gneiss: The oldest intact continental crust in the US. \u003c\/strong\u003eOne of the oldest stones on Earth, your display includes a sample of this Archaean-age crustal rock from Minnesota. 100 million years ago, geological forces pushed Morton gneiss to the surface, and 12000 years ago the glaciers covering it began receding. The rivers formed by those glaciers melting exposed some of the Morton gneiss, allowing you to take home this piece of geological history.\u003c\/p\u003e\n\u003cp\u003eWe have only a very limited amount of these samples, acquired from the private collection of a reputable fossil collector who's written some of the most authoritative books on identifying fossils and minerals of the United States.  The specimens are housed in a custom wood and acrylic 6\" freestanding display, and come with the gift box and certificate of authenticity pictured.
