On ANTIQUES ROADSHOW, an appraisal is usually the final word—but what happens when a guest brings her own receipts? In 2011, an Atlanta guest presented a brilliant royal blue enamel egg she hoped was a Fabergé masterpiece. Appraiser Sebastian Clarke wasn’t convinced, labeling the treasure, acquired by the guest for $15,000, a “Faux-berge” fake. The matter seemed closed until a second, conflicting appraisal was revealed. Was Sebastian right all along or had he made a "royal blunder"? Join host Adam Monahan as he dives into the chaos of the Russian Revolution, tracks down a world leading Fabergé expert, and cracks the case of this irksome egg.
