No harm no foul for Christie's, as a formerly "French" "19th century" "claret jug" is properly reclassified as a thousand-year-old Fatimid ewer. Now it's worth a heckuva lot more, as Reuters reports:
A 1,000-year-old carved rock crystal ewer, one of only seven known surviving examples, fetched 3.2 million pounds at auction on Tuesday, Christie's said.
The ewer is the same one that came up for auction in Britain in January this year, when it was catalogued as a 19th century French claret jug and valued at 100-200 pounds.
In fact experts now believe it is an extremely rare ewer from the Fatimid dynasty which ruled parts of northern Africa and the Middle East in the 10th-12th centuries.
