The Story


Jessica McCormack grew up in New Zealand among the treasures and curiosities of her father’s auction house, igniting a love of exploring an object’s past. A year in the jewellery department at Sotheby’s in London cemented her passion for fine jewellery. Jessica’s designs are centred on storytelling and nostalgia, weaving together emotion and history.

Jessica has two business partners. Michael Rosenfeld is a diamantaire and art collector who sources the best diamonds in the world for Jessica’s designs. Rachel Slack is a businesswoman and a member of the Oppenheimer family which has long and celebrated links with diamonds. All three have the same approach to fine jewellery, preserving the values of beauty and craftsmanship and providing the dedicated service of the old-fashioned family jeweller.

Jessica, Rachel and Michael came together because of their shared passion for diamonds and a belief that they hold special meaning in people’s lives. For them diamonds express love, relationships, families, moments that deserve to be marked.

The House


In the heart of Mayfair, 7 Carlos Place was built in the 19th century as a grand townhouse. It is where Jessica’s jewellery is designed, made and showcased. Everyone is invited to visit – it’s open six days a week and there’s no need for an appointment.

Jessica has personally curated every detail – the jewellery displays, the contemporary art and the collection of rare and unusual objects. The house is a beautiful and intimate place to select jewellery or to sit and discuss bespoke pieces with Jessica and her team.

A spirit of inspired irreverence infuses everything Jessica McCormack creates. She designs jewels to be worn now and forever, to be handed down through generations and to make new memories.

The Bespoke Jeweller

Commissioning a bespoke piece from Jessica McCormack is a highly personal experience that results in the creation of an heirloom to be passed down to future generations.

From a single ring to a major suite of jewels, Jessica McCormack personally designs each piece. Created using traditional jewellery techniques, the pieces might involve a Georgian cut-down diamond setting or the painstaking process favoured by Jessica of layering white gold over yellow gold.

The Collection

In the boutique at Carlos Place, clients can see and try Jessica’s much-loved jewellery collections. The names of these iconic collections include Tattoo, Jewels of the Urban Night, Messenger of the Gods and Perfect Storm, giving away something of their flavour and variety.

All jewels are hand-crafted using the traditional techniques that help define the house’s unique aesthetic.

The Bridal Collection

This is a highly personal experience in a warm and welcoming environment. There is a beautiful range of engagement rings to choose from, including large cushion-cut diamonds set minimally in yellow gold bands, through to Jessica’s iconic Wings of Desire and her avant-garde Tetris designs, all engagement rings that capture Jessica’s unique style.

Alternatively, clients can commission
a bespoke ring.
