How this works
You stay in control. Before manufacturing begins.
Once your order is placed, we don't go straight into manufacturing. The atelier first prepares everything you need to be sure — and nothing is made until you approve it.
A full CAD design
A precise 3D render showing the exact piece we will make for you.
The complete specifications
Stones, metals, sizes, settings and finish — set out clearly so nothing is left to interpretation.
Photographs of the actual stones
And, where useful, short videos — so you see the exact stones we will set, not stock images.
Manufacturing only begins after you have reviewed all of this and confirmed you are happy. Your piece is made on your approval, not before.
Worldwide delivery
Crafted in London. Sent wherever you are.
We work from our atelier in Hatton Garden — but the stones, the metals, the inspiration and the craftsmanship behind each piece can come together from all over the world. In a way, the piece you wear carries a little of the world with it.
Secure, insured delivery
Every order is sent fully insured by carriers we trust, with tracking from the moment your piece leaves the atelier — so you know exactly where it is, every step of the way.
A note on local taxes
For deliveries outside the UK, import duty, customs charges or local VAT may apply at the destination. These are set by the country you're in and are the customer's responsibility — but we'll happily guide you through what to expect, and our delivery partner will help with the formalities so nothing comes as a surprise.
About this piece
A bold interplay of form and colour defines this made-to-order cocktail ring, where a marquise-cut lab-grown diamond in a striking deep forest-green is set at a deliberate tilt within a split, asymmetric platinum cradle. The hammered rose gold band provides warmth and texture, rising asymmetrically to cradle the stone. Along the lower arc, a row of micro-bezel-set tsavorites accentuates the diamond’s silhouette, leaving the upper half in open negative space for a sense of lift and lightness. Concealed within the interior gallery, three icy white baguette diamonds are set horizontally—an intimate detail known only to the wearer. This architectural design balances drama with refined craftsmanship, offering a distinctive statement for evening occasions.

The story of this design
We began with a line, not a stone: the sharp, deliberate sweep of a marquise cut, and asked what it would take to house that drama honestly. Platinum gave us the cool, exacting frame The Architect demands; rose gold answered with warmth, a quiet argument between structure and softness that we didn't want resolved. The forest-green tsavorite arrived as punctuation, not decoration, catching light the way a well-placed window catches evening sun. We textured the surfaces so the piece would feel considered under the fingertip, not merely admired at a distance. This ring is built for the moment a room notices you before you speak — for evenings that ask for presence, and for the particular confidence of wearing something asymmetric on purpose, deliberately unresolved, entirely yours.
Metals & stones in this piece
Platinum is a naturally white, dense precious metal prized for its exceptional durability and hypoallergenic properties. Its high density makes it extremely resistant to wear, meaning it holds its shape and security for stones superbly over a lifetime. The rose gold component is an alloy of gold, copper, and silver, giving it its warm pink hue. Its colour is stable, though like all golds, it can develop a soft patina with daily wear. The lab-grown diamond is physically, chemically, and optically identical to a mined diamond, offering the same supreme hardness (10 on the Mohs scale) and brilliant fire. A textured finish on the metal will highlight the material's character; this satin or brushed effect will soften very gradually with time but retains its distinctive look beautifully.
Caring for this piece
Clean your platinum and rose gold jewellery with a soft brush, warm water, and a drop of mild washing-up liquid. Rinse thoroughly and pat dry with a soft, lint-free cloth. For the lab-grown diamond, you can use the same method; its hardness makes it resistant to scratches. Store pieces separately in a soft pouch or box to prevent the textured finish from being rubbed by other items. Avoid exposing rose gold to harsh chemicals like chlorine, which can affect its alloyed metals. Remove jewellery during strenuous activities, gardening, or household cleaning to protect the textured finish from knocks and abrasion.
