Trillion forest-green diamond cocktail ring in platinum and rose gold
A trillion-cut forest-green lab-grown diamond, tension-set in platinum, unfurls into rose gold filaments that spiral like fern fronds down the band. Flush-set baguette tsavorites and garnets deepen the green spectrum, while satin platinum contrasts with polished rose gold—crafted as a quiet statement for the hand.

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 studio-approved cocktail ring is a celebration of sculptural form and botanical detail. At its heart, a trillion-cut fancy vivid forest-green lab-grown diamond is tension-suspended within an open platinum crown, its three prongs tapering into rose gold filaments that spiral gracefully down the band like unfurling fern fronds. The satin-finished platinum body is accented by polished rose gold vines, while baguette-cut tsavorites are flush-set into the rose gold shoulder channels, intensifying the green gradient. Garnet accents add a subtle warmth, creating a dynamic interplay of colour and elevation across the piece. Crafted to order, each detail is reviewed by our studio before production, ensuring a truly considered and original statement ring.

The story of this design
We began with the trillion cut itself—that stark triangular geometry—and wondered what it might feel like softened, worn as something closer to a held breath than a declaration. The forest-green diamond has a depth that shifts with candlelight and streetlight alike, so we set it in platinum for its cool, unshowy strength, then let rose gold move around it, warming the edges where sculpture meets skin. Garnet accents were chosen to echo that same undertone of red-warmth-within-dark, small anchors of colour that keep the eye moving rather than resting. The satin finish quiets the drama just enough. This is a ring for evenings that matter to you alone—for The Romantic who wants to feel dressed in feeling, not just adorned. We made it to be worn boldly, and thought about tenderly.
Metals & stones in this piece
Platinum is a prestigious metal cherished for its rarity, density, and naturally white lustre, which does not fade or tarnish over time. Its remarkable durability makes it ideal for everyday wear, though its softness relative to other precious metals means it develops a patina—a subtle sheen from daily use—that many find appealing as it tells the story of the piece. Yellow gold, alloyed with metals like copper and zinc, offers a warm, timeless hue and is highly durable, though slightly softer than platinum. Over time, gold may show light scratches, but these can often be polished out, restoring its original brilliance. Lab-grown diamonds share the same physical, chemical, and optical properties as mined diamonds, offering exceptional hardness (10 on the Mohs scale) and durability. Their brilliance remains intact with proper care, though they can accumulate oils and dirt that dull their sparkle. A satin finish, with its soft, brushed appearance, is less prone to showing scratches than a high-polish surface, making it a practical choice for pieces worn daily. Over time, the satin finish may gently smooth out but can be professionally retextured if desired.
Caring for this piece
To maintain the beauty of your platinum, yellow gold, and lab-grown diamond jewellery, clean it regularly with a soft-bristled brush and a mild solution of warm water and dish soap. Gently scrub the piece, paying attention to the setting and any intricate details where dirt may accumulate. Rinse thoroughly and dry with a soft, lint-free cloth. Store your jewellery separately in a fabric-lined box or pouch to prevent scratches, particularly when travelling. Avoid exposing your pieces to harsh chemicals, such as chlorine, bleach, or household cleaners, as these can damage both the metals and the diamond. Remove your jewellery before swimming, showering, or engaging in activities that may subject it to hard knocks or abrasions. For satin-finished pieces, avoid using polishing cloths designed for high-polish surfaces, as these can alter the texture. If your jewellery requires professional attention, such as retexturing or deep cleaning, consult your jeweller for expert care.
