Jessica McCormack is one of the most influential jewellery designers working in London today, recognised for a style that draws on Georgian and Victorian precedents while remaining unmistakably modern. From a townhouse atelier on Carlos Place in Mayfair, she has built a global practice that supplies private clients with bespoke and ready-to-wear pieces grounded in vintage diamond cuts, blackened gold, and the visual language of nineteenth-century mourning and sentimental jewellery, restaged for the present.

Background

McCormack was born in New Zealand into a family with a long-standing involvement in the antiques trade. She trained at the Royal College of Art in London, where her postgraduate work focused on the technical traditions of diamond setting and the historical study of period jewellery. After graduation she worked with auction houses and private dealers in the secondary market, building a working knowledge of Georgian, Victorian, and Edwardian goldsmithing that would later define her aesthetic.

Studio and House Style

The house was founded in 2006 and moved to its present Mayfair townhouse a few years later. The studio occupies multiple floors of a Georgian building, with workshop, design, and showroom under one roof, an arrangement deliberately modelled on the older trade convention of the bespoke house. The signature device is the button-back setting, in which an old-cut diamond is mounted in yellow gold that is blackened on its visible reverse, then closed with a domed back plate that recalls the construction of antique cluster rings. The technique compresses light into the stone and gives finished pieces a depth that flat-back modern settings do not produce.

Other recurring devices include cushion-cut and old European-cut diamonds rather than modern brilliants, hand-engraved gold, gypsy-set diamonds in heavy yellow gold bands, and ear furniture inspired by Georgian girandoles and pendeloques. McCormack works extensively with antique stones recut sympathetically, a position that aligns the house with the wider trade conversation about the carbon and provenance footprint of newly mined goods.

Clientele and Reception

The house has been the subject of features in The Financial Times, Vogue, and the trade press, and its private client list extends across Europe, North America, and East Asia. Collaborations with the Natural History Museum and ongoing engagement with the auction trade have reinforced McCormack's position at the intersection of contemporary design and historical scholarship. Notable commissions include engagement and wedding pieces for figures in fashion, film, and music, often executed in collaboration with the client over a series of bench appointments rather than from a fixed catalogue.

Trade Position

Within the contemporary fine jewellery sector McCormack occupies a specific niche: an independent house with an explicit historical vocabulary, working at couture price points without diluting into accessories or licensed lines. The studio model, anchored by an in-house workshop and a single physical address, has remained consistent since its founding and is sometimes cited in the trade as a counter-example to the corporate model that dominates the maison segment.
