With a focus on redefning the boundaries of corporate chic, Rush Hour introduces new styles, that compliment an energy that is spirited and bold. Using timeless materials – white and yellow gold, pearls and diamonds – in combination with curvaceous forms, the collection plays with the balance between classic and contemporary design. Each piece has been realised with a sense of strength and fuidity, aiming to embody these characteristics, inspiring and empowering their wearer round the clock, while remaining silently ftted to the body.

Diamonds ‘Til Late
The Rush Hour collection has a cast of show-stopping diamonds, whether acting as a fickering full stop on a ‘Til Late Earring or the sparkling centre piece of the Oval Diamond Double Take Ring, these diamonds have been hand selected for their unequivocal quality and unique character. The diamonds are positioned to compliment the concept of the ‘curve’ throughout the collection, which is an awareness to the movements and shapes of the body, that means to ensure the comfort of the wearer.
The design of the ‘Til Late Diamond Torque intentionally places the 8.01ct oval-shaped diamond underneath one collarbone and elegantly undulates around the other.
Similarly, the range of ‘Til Late Earrings subtly loop under the earlobe. The collection sees the return of our signature use of blackening which, when paired with the elevated glow of gold, creates a beautiful contrast that intensifes the dazzle of the diamond pave it surrounds.
























Balanced Pearls
Pearls have been woven into our Rush Hour collection in multiple shapes and sizes, transforming the classic motif of the pearl into a modern jewellery essential. Pieces such as the ‘Til Late Pearl Torque exhibit the symmetry between the sculptural curvature of the white gold and the natural shape of the pearl which sits, as if balancing, below the collar bone.















High Polish
The Rush Hour collection sees the introduction of a new JM design feature, showcasing pieces with a highly polished and refective fnish. While all the pieces in the collection are complete with ‘high polish’, none boast it better than the range of ‘Til Late Yellow Gold pieces. The large surface areas of these voluminous pieces ofer plenty of room for lustre, proudly showing of the highly polished fnish. Whether complimented by the sparkle of an eight-carat diamond or the soft iridescence of a pearl, the high polish is unapologetically striking.














Mixed Metals
Although Rush Hour takes on a new level of contemporary style, Jessica’s love of antique jewellery techniques is subtly embedded into the technical excellence of this collection. The classic Victorian ‘doublé’ technique sees the joining of white and yellow gold, and our goldsmiths have made these meetings seamless. Pieces such as the Double Take Rings appear as one continuous form that fows so gracefully around the fnger that the wearer would never know where one gold starts, and the other begins, if it weren’t for the colour. Maintaining the JM approach to prioritising comfort, the ‘doublé’ pieces are hollow to reduce their weight on the body yet crafted with a thick interior wall to completely prevent the possibility of misshaping.
