Rockefeller’s rock is headed to auction

A 18.04-carat Colombian emerald known as the Rockefeller Emerald is headed to auction next week and it’s expected to fetch between $4 million and $6 million.

The emerald has been owned by the Rockefeller family since in 1930, when John D. Rockefeller Jr. bought the brooch that originally held the gem for his wife Abby. When she died, the brooch was broken down and the stones were distributed amongst her children. The late David Rockefeller, her youngest son, was the recipient of the stone and he had it — along with some diamonds — turned into a ring.

It’ll hit the auction block at Christie’s Magnificent Jewels auction in New York. The listing notes that the gem is described by the American Gemological Laboratories as “exceptional,” and that it “possesses what the AGL calls an “unusual combination of size, provenance, absence of treatment and quality factors [that contribute] favorably to its rarity and desirability.””

David died in March, and since, an assortment of his belongings and property has been making its was to sale. Last week, his 40-foot-wide townhouse at 146 East 65th Street hit the market asking $32.5 million, and next year Christie’s will be selling some 2,000 pieces of his art and furniture at auction.
