Engagement rings

Each engagement ring is uniquely made to order in our London based atelier - crafted from scratch and tailored to your story. We are a small (and young) jewellery house that simply wants to share in a journey that brings us such joy.

Unique & Personal

Bespoke engagement rings crafted in London

Our bespoke portfolio provides a curated selection of pieces created previously. We take great joy in pushing creative boundaries and exploring the undiscovered and will delight in designing a piece tailored to your story.

Creating bespoke jewellery and engagement rings is deeply embedded in our roots and is the very founding of our journey. Unconstrained by a set collection, each bespoke engagement ring is made to order, designed and crafted in our London atelier. With an ethos centred on "stone led design", a theme of elegant proportions, intricate details and a contemporary finish flows through each piece.

Sustainability & ethical sourcing

Expedition sourced gemstones

We are proud of the advances we are making in pursuit of pioneering a new era of responsible luxury. We aren't here to say we are perfect, we simply want to explain our approach, the positive practices we adopt and highlight our continual pursuit of perfection...
 

This all starts with our expeditions. With expeditions to far flung corners of the earth in search of precious gems, we want to immerse you in our world. We are building long term personal relationships to create a sustainable future for the industry we love.
