The Ziwiye hoard


The Ziwiye hoard was uncovered on the south shore of Lake Urmia in Ziwiyeh, Kurdistan Province, Iran, in 1947.


The Iranian plateau was the crossroads of a cultural highway as well as a physical one ... on the "Silk Road" of the ancient world. The hoard contains objects of four distinct styles: Assyrian, Scythian, proto-Achaemenid, and the locals.


The hoard contains gold, silver and ivory objects of exquisite workmanship and are dated to around 700 B.C.

Christie's auctions 101.74 ct Perfect Diamond

(Reuters) - A pear-shaped colorless diamond that is the largest ever offered at auction sold for a record of nearly $27 million in a Geneva auction, where records were also set for the prices of pearls and sapphires, auctioneer Christie's said.

The 101.73 carat "Winston Legacy" diamond, the centerpiece of the Magnificent Jewels auction, was bought by jewelry and watch firm Harry Winston for 25.9 million Swiss francs ($26.7 million) on Wednesday.

"Harry Winston acquired the most perfect diamond ever offered for sale at auction," said Rahul Kadakia, head of Jewelry, Christie's Switzerland and Americas,

Sotheby's also sold a 74.53-carat fancy yellow diamond that once belonged to Ahmad Shah Qajar, the shah of Persia from 1909 to 1925 and the last ruler of the Qajar dynasty. Its sale for nearly $3 million set both an auction record and a record price per carat — an eye-popping $40,061 per carat — for a fancy yellow diamond.
