The Sotheby's auction house in New York is about to auction off a very valuable necklace from David Morris (a famed London jeweler). Link:
David Morris An Exceptional Sapphire and Diamond Necklace
Sotheby's gave it an estimated value of 3,000,000 - 5,000,000 USD. This market resolves YES if the final sale price listed on the Sotheby's website is >$5,000,000.
Resolution details:
Example from a past auction: this unmounted diamond lists "Lot Sold
3,871,500 CHF" on the Sotheby's website. This is the equivalent number I will use.
Note that this final listed sale price typically includes the buyer's premium.
If the lot is withdrawn before the auction, or it fails to sell, this market resolves NO. It only resolves YES with a listed sale price from this auction of >$5 million.
