Fancy Vivid Blue Diamond Ring to Be Auctioned By Christie’s

The Bulgari Blue Diamond—a two-stone diamond ring designed
by the legendary house of Bulgari in the 1970s—will be auctioned as part of
Christie’s New York Jewels sale Oct. 20.

The ring features a triangular, colorless diamond of 9.87
cts. paired with a triangular Fancy Vivid blue diamond of 10.95 ct.—the largest
Fancy Vivid blue diamond of this cut ever to be offered at auction. Only one in
about 10 million will possess a color pure enough to qualify as Fancy Vivid,
the auction house notes.

The ring is expected to fetch more than $12 million, Christie’s
says.
