The Rockefeller Emerald, an 18.04 ct. “exceptional” Colombian gem, will highlight Christie’s June 20 Magnificent Jewels sale in New York City.
The step-cut stone, mounted with diamonds in a piece by designer Raymond C. Yard, is considered one of the finest emeralds ever to be auctioned. It carries a $4,000,000 to $6,000,000 estimate.
Yard designed the piece for David Rockefeller following the death of his mother, Abby Aldrich Rockefeller, in 1948. It is being put up for sale by an American collector.
American Gemological Laboratories describes the stone as “exceptional” with “an unusual combination of size, provenance, absence of treatment, and quality factors.”
