The Miss Independent hitmaker purchased the gold and turquoise antique at a sale in the UK in July, but her request to take it back to her native America was turned down by officials.
She told the Daily Star: "I got up at 4am to start bidding on the auction. We put in an export request but I can't take it out of the UK as they've named it a national treasure."
Clarkson admits she is a huge fan of British culture, and even took time out of her busy touring schedule to visit the historic buildings featured in 2005 film Pride & Prejudice, based on the 1813 novel by Austen.
She added: "I had my sister with me and we went to Derbyshire to see where the version of Pride And Prejudice featuring Kiera Knightley was filmed. Y'all (you all) live in such a beautiful place.
"When I'm here (in Britain) there's so much to see as I'm a really big history nerd. All I've done for the past decade is see the tour bus so we thought we'd do something different."
