Located on one of the world’s most prestigious shopping streets, our Madison Avenue store is our home away from home. Set across two floors of a beautiful Beaux-Arts building established in 1879, our Madison Avenue store is home to the complete collection of signature JM pieces, as well as our Exceptional Stones, exclusive to the New York store.


Echoing the distinctive style of our London boutiques, the space showcases a carefully curated multi-disciplinary art collection. Paintings, photography, antiques, and objets are displayed alongside the jewels, creating an inspiring and immersive experience for every guest.
From custom fireplace tiles, by Petra Palumbo, to a hand painted mural by Kreh Mellick on the entrance wall, the Madison Avenue store interiors create an environment that is truly unique to Jessica McCormack. From a Black Forest bench which plays music on opening, through to a velvet dog bed
for furry visitors and bespoke tulipieres – the store interiors are as eclectic as they are welcoming.
I am very excited to be opening our first international store in New York. We have seen such enthusiasm and interest from our US clients, so it feels great to finally have a space for them to visit us, closer to home. I have always loved Manhattan and to be opening on one of its most iconic shopping streets is the perfect opportunity to reach more people, while welcoming old and new clients.
Jessica McCormack, Founder and Creative Director
