The stone, named "The Sky Blue Diamond", weighs 8.01 carats
and is mounted on a ring by jeweler Cartier. It will be sold at
Sotheby's Nov. 16 "Magnificent Jewels and Noble Jewels" in
Geneva, with a pre-sale estimate of $15 million-$25 million.
"It really is the color of a summer sky with this beautiful
brilliance and subtlety about the stone," said David Bennett,
worldwide chairman of Sotheby's International jeweler division.
