11th C Fatimid Rock Crystal auction after misidentification

A rare Islamic rock crystal ewer is reclassified after being sold as post-industrial French antique for about UK£200. It will auction at Christie's London this October for more than UK£3 million. It is one of eight known extant rock crystal ewers from the period. (picture)

The Egyptian ewer, which dates to around 1000 C.E. featured two cheetahs. The original mouth and handle were broken and replaced with gold ones from a later time period.
