When the owner of this beautiful ring bought it, she thought it was a cubic zirconia (which was acceptable, given the $30 she paid for it). After discovering some hallmarks and doing a little research, however, she discovered that she may have gotten more than she bargained for! After taking the ring to Antiques Roadshow to get it appraised, her suspicions were confirmed: it was actually a French Art Deco diamond ring from 1930, worth 25-30,000 dollars!
