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
This made-to-order Studio Product is a bold statement ring, expertly crafted in polished platinum with sculptural rose gold accents. At its heart, a marquise-cut lab-grown diamond in vivid electric-blue draws the eye, while asymmetrical pear-shaped morganites in soft peach-pink embrace the centre, echoing the fluidity of water. Sapphire pavé accents trace the platinum band, offering a refined contrast and reinforcing the aquatic motif. The under-gallery is thoughtfully textured to suggest rippling movement, ensuring the design feels dynamic from every angle. Each element is carefully balanced, resulting in a contemporary piece that feels intimate, dramatic, and unmistakably original. The shown configuration is reviewed by our studio before production, ensuring every detail meets our highest standards.

The story of this design
We began with the marquise itself, that long, deliberate point of light, and let it dictate the ring's temper: sculptural, unhurried, made for evening. Platinum carries the diamonds because it is quiet and exacting, holding their brilliance without competing for it, while rose gold moves beneath in warmer counterpoint, the way memory warms fact. The sapphire accent arrived almost as punctuation, an electric-blue breath against the polished ripple of stones, giving the eye somewhere unexpected to rest.
This is a piece for the moment before a room notices you, the pause before a door opens. We imagine it on a hand that has already decided something, worn not to ask for attention but to meet it squarely. In our workshop it stands as a small act of drama held in careful metal, made for those who wear certainty lightly.
Metals & stones in this piece
Platinum is a prestigious and naturally white metal, prized for its rarity, density, and enduring lustre. Unlike other precious metals, it does not tarnish or discolour with time, maintaining its cool, luminous sheen. Its remarkable durability—resistant to wear and corrosion—makes it an ideal choice for daily wear, though its softness relative to hardness means it develops a gentle patina over years of use, a characteristic many cherish as a sign of authenticity and lived-in elegance. Lab-grown diamonds, chemically and optically identical to mined diamonds, offer exceptional brilliance and hardness (10 on the Mohs scale), ensuring they resist scratching and retain their fire for generations. A polished finish on platinum enhances its reflective quality, though this surface may soften subtly with wear, adding to the piece’s unique character rather than detracting from it.
Caring for this piece
To preserve your platinum and lab-grown diamond jewellery, clean it regularly with a soft-bristled brush and warm, soapy water, then rinse and pat dry with a lint-free cloth. Store pieces separately in a fabric-lined box or pouch to prevent scratches from other jewellery. Avoid exposing platinum to harsh chemicals, such as chlorine or bleach, which can weaken the metal over time, and remove your jewellery before swimming, gardening, or engaging in physical activities that may subject it to knocks or abrasions. While platinum is highly durable, its polished surface may develop a natural patina; if you prefer a high-shine finish, a jeweller can repolish it for you. Handle your pieces with care to maintain their beauty for years to come.
