Sotheby's auction house will now hold the world's largest yellow diamond's auction next month, which is expected to bag $25 million.

The rock, one of the world's largest cut diamonds of any colour, is mounted as a ring and sparkles with "extraordinary fire and brilliance," the auction house said Wednesday.
The asking price for the privately-owned gem is $15-25 million (11-18 million euros), but if recent auctions are any guide it could fetch more.
When the world's largest orange diamond went under the hammer last November at Christie's in Geneva, it raked in $35.5 million compared to its $17-20 million price tag.
And a Sotheby's auction the next day saw the world's largest pink diamond, known as the Pink Star, fetch $83 million -- $23 million above the asking price.
The auction house was, however, forced last month to take back the Pink Star after the buyer defaulted on the payment.
