|An 18.04 carat Colombian emerald once owned by the Rockefeller family appears at Christie's Magnificent Jewel auction. John D. Rockefeller Jr. acquired the octagonal step-cut emerald in 1930. The American Gemological Laboratories (AGL) describes the jewel as "exceptional," adding that it's an "unusual combination of size, provenance, absence of treatment and quality factors [that contribute] favorably to its rarity and desirability."|
The emerald was expected to sell for between $4 million and $6 million.
