Congrats to Shaika Pollard for guessing correctly first. Scientists using two different age-determining techniques have shown that a tiny zircon crystal found on a sheep ranch in western Australia dates back to 4.4 billion years ago. "This is the oldest reliably dated piece of the Earth that we have, that anyone knows of," John Valley told CBS News. Valley, a University of Wisconsin geoscience professor, led the research team. Writing in the journal Nature Geoscience on Sunday, the team said the discovery indicates that Earth's crust formed relatively soon after the planet formed and that the little gem was a remnant of it. Zircon is the correct answer Trivia Time!!!!! One guess only any more than that will only go by the first response. This is for a 2 hour time length and the winner gets a $25 in store gift certificate that can be used for anything. Will mail if you don’t live near by and you can purchase directly off our website at andersonjewelers.com What is considered to be the oldest mineral mined today for gemstones?
