A couple from Granite Bay, California went to Crater of Diamonds State Park in Arkansas a couple weeks ago. It’s the only diamond mine in the U.S. that’s open to the public. And in just 40 minutes, they struck it rich. They discovered a 4.38-carat yellow diamond, and they don’t know how much it’s worth yet. It’s the largest gemstone discovered at the site this year. The park allows visitors to keep anything they find! Does this entice you to head to the park?
