The Rockefeller Sapphire — A Burmese Cushion of Documented Provenance
The Rockefeller Sapphire — A Burmese Cushion of Documented Provenance
A 62.02-carat royal-blue Burma stone that has changed hands at auction four times
The Rockefeller Sapphire is a 62.02-carat cushion-cut Burmese sapphire of intense royal-blue colour, mounted as a ring by Raymond Yard. The stone is one of the most thoroughly documented coloured-stone provenances in twentieth-century American collecting, having been acquired in 1934 by John D. Rockefeller Jr. from the estate of an Indian maharaja, retained in the family until 1971, and offered subsequently at multiple auctions, most recently at Christie's New York. Its combination of size, Burmese origin, documented historical provenance, and Yard mounting make it a reference example for the auction premium attached to top-tier Burma corundum.
Provenance and ownership history
John D. Rockefeller Jr. acquired the sapphire in 1934 from the estate of the Nizam of Hyderabad, one of the great gem-collecting Indian princely households of the late colonial period. The stone was originally part of a brooch and was subsequently reset by Raymond Yard, who created a series of Art Deco-influenced platinum-and-diamond mounts for Rockefeller-family stones. The Rockefeller Sapphire was reset by Yard at least twice over the course of its time in family ownership.
The stone was sold by the family in 1971. It re-emerged at Sotheby's in 1980, returning to auction at Christie's New York in 1988 and 2001. Each appearance set or approached the price-per-carat benchmark for Burmese sapphire of comparable size at the date of sale. The most recent Christie's sale was reported with the stone in a Yard-style cushion-cut mount flanked by triangular shield-shape diamonds.
Stone characteristics
The Rockefeller Sapphire weighs 62.02 carats and is cut as a cushion. The colour is described in laboratory and auction documentation as a deeply saturated, slightly violetish royal blue, the canonical "Burma blue" associated with Mogok-region production. Clarity is high for the species and origin, with the velvety transparency that fine Burmese sapphire commonly displays in well-cut large stones.
Origin opinions accompanying the stone at successive auctions have consistently confirmed Burma. Heat treatment status has been the subject of greater interrogation across the stone's auction history; the most recent reports describe the sapphire as showing characteristics consistent with no thermal enhancement, a property that, in a stone of this size, materially elevates value.
Why Burmese origin matters
Burmese sapphire from the Mogok region commands the highest per-carat premium of any sapphire origin at the top of the market, alongside Kashmir. The colour character — a saturated, slightly violetish royal blue with notable velvety transparency under varied lighting — is the reference benchmark against which other origins are evaluated. Mogok production has historically been irregular and is currently subject to significant trade restriction, which compounds the rarity of large fine Burma stones.
Stones of the Rockefeller Sapphire's calibre — above 50 carats, fine colour, Burma, no heat — appear at auction perhaps once every several years. Their prices reflect this scarcity rather than the linear-per-carat scaling typical of more abundant material.
The Yard mount
Raymond Yard founded his New York firm in 1922 and worked extensively for the Rockefeller family from the 1920s onwards. Yard's stylistic vocabulary drew on Art Deco geometry softened by jewellery sensibility, and the Yard mount on the Rockefeller Sapphire — flanking diamonds in shield or triangular shapes — is consistent with the firm's signature treatment of important coloured-stone centres. The Yard provenance contributes a documented designer-attribution premium to the stone's auction value.
In the trade
The Rockefeller Sapphire is one of a small group of named historical Burma sapphires whose auction history establishes per-carat reference points for the top of the species. Buyers and consignors evaluating very fine large Burmese sapphires use the Rockefeller result as a reference for the high end of the price distribution, alongside the Bismarck Sapphire, the Hill Sapphire, and recent Mogok-origin lots from Christie's, Sotheby's, and Bonhams.
