Oldest Earth - Jack Hills Zircon - Classic Riker Box Specimen

This specimen is a small piece of the Jack Hills formation north of Perth in Western Australia (pictured above).  The rough, sedimentary layers of the Jack Hills formation are 3.3 billion years old, but they also contain much older zircon crystals across a range of time from 3.6 to nearly 4.4 billion years old.   The specimen measures 1x1 cm and is enclosed inside an acrylic specimen jar. The jar is enclosed inside a classic, glass-topped riker display case. A small information card is also enclosed. Please Note: These specimens were collected in accordance with Australia's cultural heritage and mining laws. That said, this site is now permanently closed to new mining and no further exports are expected. As such, it is likely these specimens are the only pieces we will ever see outside of Australia or available to the general public.
