Your Perfect Engagement Ring does not exist...


Exclusive, Custom Made

Engagement Rings.


The anti-standard.


Lydia McCarthy-Keen takes commissions for exclusive, ethical and British made luxury jewellery.

These bespoke creations are timeless in design, and conceptualised in close conversation with the client to reflect their needs and aesthetic.

Each piece is individually designed and hand painted before a to scale model is first printed in 3D for client approval.


''An exciting, unexpected, and beautiful experience.''
