Sotheby’s Geneva will auction, next month, the 100.09-carat Graff Vivid Yellow, one of the largest fancy vivid yellow diamonds in the world.

The Graff Vivid Yellow, the colour of a daffodil and weighing 100.09 carats, figures among a wide range of pieces for sale at Sotheby’s spring Magnificent Jewels and Nobel Jewels auction in the Swiss city on May 13.

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 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 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.

Sotheby’s still holds the world record price for a diamond sale, even after the default. In November 2010 it sold another pink diamond — the 24.78-carat “Graff Pink” — for $46 million in another auction in Geneva.
