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
The Obsidian Interval Chain is a studio-approved design built around weight, rhythm and quiet tension. Its 6mm platinum curb links are deliberately substantial, with every sixth link interrupted by an integral sculptural medallion rather than a suspended pendant, keeping the silhouette clean, masculine and engineered.
At the centre of the design is a flush-set 2.50ct cushion fancy vivid teal blue lab-grown diamond, chosen as the focal point for its saturated colour and strong cut shape. Jet black baguette onyx is channel-set as a linear side feature, framing the diamond with a sharp architectural contrast while remaining secondary to the teal centre stone.
The shown configuration pairs brushed platinum with controlled polished black rhodium detailing, creating depth without excessive brightness. Made to order as a Studio Product, the piece is reviewed by our studio before production so the chain length, clasp engineering, stone layout and finishing balance can be refined for the final wearer.

Metals & stones in this piece
Platinum, a strong and durable metal, is perfectly complemented by the warm, elegant tones of rose gold. The brushed finish on these metals will gradually wear to a soft sheen over time, developing a beautiful patina that reflects the piece's history. Lab-grown diamonds, with their exceptional brilliance and fire, are a stunning match for these metals. They possess the same physical and optical properties as natural diamonds but are more environmentally friendly. The combination of platinum, rose gold, and lab-grown diamonds results in a piece of jewellery that is not only visually striking but also remarkably resilient, capable of withstanding the tests of daily wear with minimal maintenance. As the brushed finish matures, it will continue to exude a sense of sophistication and timeless style.
Caring for this piece
To keep your platinum and rose gold jewellery with lab-grown diamonds looking its best, clean it regularly with mild soap and warm water. A soft-bristled toothbrush can be used to gently remove any debris. Avoid exposing your jewellery to harsh chemicals or extreme temperatures. When not worn, store your piece separately in a soft pouch or box to prevent scratching. Regular polishing by a professional jeweller can help maintain the brushed finish, ensuring your jewellery remains a treasured possession for years to come.
