Schlumberger Bird on a Rock
Schlumberger Bird on a Rock
The signature Tiffany brooch design that placed a diamond bird atop a coloured gemstone
Bird on a Rock is a signature brooch design by Jean Schlumberger for Tiffany & Co., first executed in 1965 and continuously produced in variations across the decades since. The conceit is straightforward: a stylised bird in pavé-set diamonds and yellow-gold accents perches on top of a large faceted or cabochon gemstone, the so-called rock, which forms the body of the piece. The design has appeared in scores of variations — different birds, different rocks, different gemstone accents — and remains in active production within the contemporary Tiffany Schlumberger collection alongside its mid-century antecedents at auction.
The original design conceit
The 1965 commission that produced the canonical Bird on a Rock was driven by Tiffany's wish to find a permanent display mount for the 128.54-carat Tiffany Yellow Diamond, the cushion brilliant Charles Lewis Tiffany had acquired in 1878 and which George Frederick Kunz had cut to George Kunz's specifications. The diamond was too large for any conventional setting, and Schlumberger's design — the bird perched atop the stone, gripping it with its talons rather than enclosing it — solved the display problem while creating a distinctive piece in its own right. The diamond reads as the dominant feature, the bird as a bright, vivid figure standing on top of it.
The bird itself is a small object, perhaps an inch or so from beak to tail-feather, with the body in pavé-set white diamond on platinum and the beak, eye, and feet picked out in yellow gold or coloured-stone accents. The posture is forward-leaning and alert rather than symmetrically poised, which gives the piece its characteristic liveliness even at small scale.
The variations
Beyond the iconic Tiffany Yellow Diamond version, Bird on a Rock pieces have been produced with citrine, kunzite, tanzanite, turquoise, aquamarine, morganite, beryl, tourmaline, sapphire, ruby, and emerald rocks. Each variation is essentially bespoke; even contemporary production within the Tiffany Schlumberger collection involves significant individual variation in the bird's posture, the cut of the rock, the colour treatment of the accents, and the proportional relationship between bird and stone. Some pieces use the rock as a faceted brilliant; others as a cabochon or fancy cut; the design is permissive.
The mid-century examples — those produced during Schlumberger's lifetime, before his death in 1987 — are particularly pursued by collectors. Vintage Birds with original construction, complete signatures, and good rock material routinely realise five- and six-figure prices at the major auction houses, with the precise figure depending on the rock species, the size and quality of the rock, the integrity of the bird's pavé, and any provenance footnote.
Diana Vreeland and the cultural footprint
Diana Vreeland, the editor-in-chief of Vogue in the 1960s, is one of several mid-century cultural figures associated with the Bird on a Rock and with Schlumberger more broadly. The pieces appeared in editorial photography, on the cover of catalogues, and on the lapels of sufficiently prominent clients that the design became a shorthand for a particular kind of New York high-jewellery sensibility. The Tiffany flagship store on Fifth Avenue continues to display the Tiffany Yellow Diamond on a Bird on a Rock mount as a brand fixture, and the design has appeared in promotional photography for major store anniversaries and for film tie-ins, including the Audrey Hepburn images associated with Breakfast at Tiffany's.
Hallmarks and authentication
Authentic Bird on a Rock pieces carry both the Schlumberger maker's mark and the Tiffany & Co. retailer's stamp, the standard Schlumberger double signature. Vintage examples produced or finished in Paris may also carry French assay marks. Authentication of unsigned or partially signed pieces — and reproductions and unauthorised copies have appeared in the secondary market — requires examination by a Schlumberger or Tiffany specialist, ideally with reference to the firm's archival records.
The construction tells: the talons should grip the rock convincingly, with proportional relationship to the stone's crown facets; the pavé on the bird's body should be tight, regular, and well-finished; the gold accents should sit cleanly without solder shadow. Loose, lazy, or sloppy construction is a strong indicator that a piece is either unauthorised or a heavily restored vintage example.
Position in the market
The Bird on a Rock is one of the most recognisable pieces of twentieth-century high jewellery. It is reproduced in trade publications, displayed in major museums in connection with Schlumberger retrospectives, and pursued by serious collectors as an entry point or pillar of a Schlumberger collection. The contemporary Tiffany Schlumberger collection prices new pieces from the high five figures into the multi-million-dollar range for examples with exceptional rocks. The vintage market for signed mid-century examples runs in parallel and trades on different fundamentals — provenance, originality, and market sentiment for mid-century signed jewellery in general.
In the trade
For estate-jewellery dealers and collectors, the Bird on a Rock is the most identifiable Schlumberger piece and the most reliable point of entry into the Schlumberger market. Buyers acquiring a vintage example should expect to pay for completeness, condition, and provenance, in that order; sellers offering pieces should expect to provide complete signatures, original receipts where available, and either Tiffany archive confirmation or specialist authentication for any piece offered above standard secondary-market prices.
