Woman Bought $13 Diamond Ring At Flea Market That Sold For Over $800K At Auction.

About 30 years ago, a woman found a huge ring while visiting a flea market in London. She picked it up and assumed it was a costume ring, so she bought it. And it never left her finger for all the years that followed. Then, one day, she had it appraised. She never could have imagined just how much that ring was going to alter her life forever.
