Rahul Kadakia is the International Head of Jewellery at Christie's, the London-headquartered auction house, with global responsibility for the firm's jewellery department across its New York, Geneva, Hong Kong, and London salerooms. Kadakia has led Christie's jewellery practice through a sustained period of market expansion since the early 2010s, presiding over major collection sales that have established several of the highest prices ever paid at auction for jewellery, signed pieces, and individual coloured gemstones.

Career

Kadakia joined Christie's in 1995 and rose through the New York jewellery department, becoming Head of Jewellery for the Americas in the early 2000s and International Head of Jewellery in 2014. His career sits within the small specialist community of senior jewellery auction-house personnel, alongside François Curiel (his predecessor at Christie's) and the corresponding leadership at Sotheby's, Bonhams, and Phillips. The role combines cataloguing and valuation expertise, client relationships across a global high-net-worth clientele, and the public-facing function of presenting major lots in the saleroom and the press.

Kadakia is recognised in the trade for the breadth of his jewellery knowledge — across signed period jewellery, exceptional coloured gemstones, and contemporary high jewellery — and for the diplomatic and discreet handling required of single-owner collection sales of estates and major collectors.

The Elizabeth Taylor collection

The defining sale of Kadakia's career to date is the December 2011 auction of the jewellery, fashion, and decorative arts of Dame Elizabeth Taylor at Christie's New York. The jewellery component alone realised approximately $116 million across two evening sales and an online sale, setting numerous individual records including the highest price per carat for a colourless diamond at the time and the highest total for a single-owner jewellery collection. The Taylor sale included pieces of historic significance — La Peregrina pearl, the Krupp Diamond (renamed the Elizabeth Taylor Diamond after the sale), the Taylor-Burton Diamond — and demonstrated the contemporary auction market's appetite for jewellery with documented historical and celebrity provenance.

The Taylor sale was a watershed for jewellery auction marketing. The cataloguing, the international touring exhibition that preceded the sale, and the public communication around the lots set a template that subsequent major collection sales — the Bunny Mellon collection in 2014, the Rockefeller collection in 2018 — have followed.

Coloured-gemstone records

Kadakia has overseen sales setting records for major coloured gemstones, including the Sunrise Ruby (a 25.59-carat Burmese ruby that sold for $30.42 million at Christie's Geneva in May 2015) and significant fancy-colour diamonds. The Christie's jewellery department under his leadership has been particularly active in the upper end of the Burmese ruby and Kashmir sapphire markets, where laboratory-confirmed origin and minimal-treatment status drive auction premiums.

Kadakia is a frequent commentator on the international jewellery market, both within the trade and in the broader business and luxury press. His public appearances around major sales serve the dual function of educating the wider market on the lots' significance and reinforcing Christie's position relative to its principal competitor Sotheby's in the high-end jewellery category.

Major sales beyond Taylor

Beyond the Taylor sale, Kadakia has led a series of significant single-owner and themed jewellery auctions: the Magnificent Jewels sales held twice yearly in Geneva and New York, periodic Hong Kong jewellery auctions, and selected estate sales. The Magnificent Jewels format has become the principal vehicle through which auction-grade jewellery — major signed pieces from Cartier, Bulgari, Van Cleef & Arpels, Harry Winston, JAR, and others, along with exceptional coloured gemstones and major fancy-colour diamonds — reaches the secondary market.

Christie's under Kadakia's leadership has also pursued strategic growth in markets adjacent to traditional jewellery: signed contemporary high jewellery from JAR, Wallace Chan, and Viren Bhagat has commanded substantial premiums in his sales, and the auction-house treatment of these pieces has helped establish a secondary market for living designers comparable to that for established historical houses.

In the trade

Within the international trade, the role of International Head of Jewellery at one of the two principal auction houses is one of the most influential positions in the secondary market for fine jewellery. Decisions about cataloguing, estimate-setting, marketing, and selection of pieces for major sales shape the public perception of value across signed jewellery, period pieces, and exceptional coloured gemstones. Kadakia's tenure has coincided with significant growth in the Asian (particularly Hong Kong-based) jewellery auction market, the rise of online-only jewellery sales, and the increasing premiums attached to laboratory-confirmed exceptional provenance and treatment status.

Auction-house jewellery specialists at Kadakia's level work closely with the major coloured-stone laboratories — Gübelin, SSEF, AGL, GIA, and Lotus — whose reports underwrite the value of high-end coloured-gemstone lots. Decisions about which laboratory reports to commission for major lots, and how the resulting reports are presented in the catalogue, are part of the cataloguing craft that distinguishes a senior auction-house specialist from a generalist.

Provenance and the contemporary auction market

One of the principal features of the auction market under Kadakia's tenure has been the steady premium commanded by documented historical provenance. The Taylor sale was the most visible expression of this trend, but it has continued through subsequent auctions — pieces from the collections of the Duchess of Windsor (resold from their original 1987 disposal), Maria Callas, the Maharajas of Indore and Patiala, and other documented historical figures consistently outperform comparable unprovenanced pieces. Kadakia and the Christie's jewellery team have been instrumental in researching and presenting the documentary evidence that underpins these provenance claims, and the cataloguing for such sales typically includes substantial historical scholarship alongside the standard gemmological and stylistic analysis.

The trade has also seen growing attention to ethical and disclosure issues — Kimberley Process compliance for diamonds, treatment disclosure for coloured gemstones, and increasingly scrutiny of pre-1970 acquisition documentation for jewellery containing pieces of cultural patrimony. Auction houses operating at Kadakia's level have developed internal review processes and documentation standards reflecting these requirements, and the senior specialist's role includes the diplomatic management of consignments where provenance, restitution, or disclosure questions arise.
